After 3.5mm earphone jack, usb type-A becomes frequently used computer jack in daily office work since 1996. But from this year the usb type-A would be gradually replaced by usb type-C in the future. Now the leading company, Intel, is making efforts toward this end.
USB type-C connector is much smaller than usb type-A connector.
On American time May 24th, Intel announced that they would promote the usage of usb-C in market. They decide to free enable technology of Thunderbolt 3 for people. The usb jack will be changed to usb type-C standard for their brand computer and other external equipment in the near future.
What are the advantages for usb type-C?
- Faster data transmission speed
Intel would adopt Thunderbolt 3 technology for usb type-C. That is why the transmission speed is 4 times faster than old usb type-A.
- More convenient to connect device
We can forecast that usb type-C jack will be the trend for consumer electronics in the future. People can connect all device via only one usb type-C cable. For example, we need to use hdmi cable to connect our computer to TV. Maybe one usb type-C cable can connect computer and TV in the future.
- No need to distinguish which side for plug in
Because two sides of usb type-C can be used. For usb type-A you must plug into right way otherwise it can not work.
USB type-C jack and related products are popular now
USB type-C jack becomes more and more popular. At the beginning of this year, Apple Inc. and Google Inc. both launched new products with type C usb jack. Many companies like Dell, Lenovo etc voice support for type C device and solution.
Micro-USB, although most widely used for smart-phone charging, are not simply limited to smart-phones. With just about any current device that requires charging (like cameras and GPS devices for starters), you’ll find that they utilize micro-USBs for charging as well.
When plugged into a source of power, whether that be a wall outlet or your computer (and usually you’ll have an adapter that plugs into a wall outlet and has a USB-A port for the micro-USB cord to plug into), power is transferred through the micro-USB cord to charge your device. In the case of computers, this also connects your device to a desktop or laptop, giving you the ability to perform some different actions for your device straight from your desktop — in addition to charging, that can include viewing photos, files and more.
Fast charging and micro-USB
Charging your devices to full battery is no small feat. Especially with more advanced devices that have larger batteries, this can take a pretty long time, which you don’t have if you’ve got to be out the door in five minutes because you forgot to charge your phone overnight. As such, many different quick charging technologies have risen up
If you’ve purchased a new, current phone over the past couple of years, chances are you were notified of quick charging when you first plugged it in with your unique charger. It’s a genius idea, but just make sure you’re using a legitimate, certified quick-charge charger (the one that came with your phone is your best bet!), because lower quality quick-charge chargers can actually be damaging to your phone.
As you can see, micro-USB is a very interesting technology. Not only is it used for charging up your devices, but it’s also used for the transferring of data. By plugging in the micro-USB end of the cable into your phone and the USB-A side in your laptop, you’ll be able to transfer all sorts of data, whether that be photos, video, apps and regular everyday files.
We hope we helped you understand a little bit more about micro-USB and how we interact with it on a day-to-day basis on our devices. It really is an interesting technology, despite slowly being replaced by the much more advanced USB Type-C technology (similar in terms of size, but better in almost every way).
We’re all pretty familiar with micro-USB ports. They’re often found at the bottom of our smartphones and tablets for charging up the battery. They’re also found on a myriad of other devices and hardware in the market. But, many people don’t actually know what micro-USB charging actually does, particularly when it comes to fast charging.
Follow along below as we show you a high-level overview of what micro-USB is and how it works. We break it down into layman’s terms so anyone can understand it.
What is micro-USB?
To fully grasp what exactly a micro-USB is, you’ve got to first understand the name “USB.” USB stands for a Universal Serial Bus, and you may very well be more familiar with USB-A ports, which are the USB ports that come standard on many laptops and computers. A micro-USB is a miniature USB, and most likely (if you have an Android phone at least),you have one at the end of your smartphone or tablet charging cord. This is the piece that plugs into the micro-USB port on your smartphone or tablet.
Now, simply saying referring to a “micro-USB” is kind of a general term, as there are currently three different kinds of micro-USBs: micro-A, micro-B, and Type-C. Each of these have slight differences, like shape, inner workings, and the speed that each can perform at. Out of the three, Type-C is probably the most different, and is the direction most hardware manufacturers are heading in.
A Video Graphics Array (VGA) connector is a three-row 15-pin DE-15 connector. The 15-pin VGA connector was provided on many video cards, computer monitors, laptop computers, projectors, and high definition television sets. On laptop computers or other small devices, a mini-VGA port was sometimes used in place of the full-sized VGA connector.
Although many devices still include VGA connectors, and VGA generally coexisted with the DVI standard, VGA and DVI are both being rapidly phased out in favor of the newer and more compact HDMI and DisplayPort interface connectors.
The same VGA cable can be used with a variety of supported VGA resolutions, ranging from 640×350px @70 Hz (24 MHz of signal bandwidth) to 1280×1024px (SXGA) @85 Hz (160 MHz) and up to 2048×1536px (QXGA) @85 Hz (388 MHz). There are no standards defining the quality required for each resolution but higher-quality cables typically contain coaxial wiring and insulation that make them thicker. Shorter VGA cables are less likely to introduce significant signal degradation. A good-quality cable should not suffer from signal cross talk, whereby signals in one wire induce unwanted currents in adjacent wires, or ghosting. Ghosting occurs when impedance mismatches cause signals to be reflected. However, ghosting with long cables may be caused by equipment with incorrect signal termination or by passive cable splitters rather than the cables themselves.
There are DVI to VGA adapters and cables. As neither DVI nor VGA carry audio channels, a separate path for audio should be used, if needed.
To connect VGA to interfaces with different signaling and vice versa converters may be used. Most of them need an external power source to operate and are inherently lossy.
VGA to SCART converter that passes through color information is possible, because VGA — SCART RGB signals are electrically compatible, except for synchronization. Modern graphics adapters are able to widely modify their signal in software, including refresh rate, sync length, polarity and number of blank lines. Particular issues include whether or not interlacing is supported as well as if the resolution can be set to 720×576 in PAL countries. Under these strict conditions, a simple circuit to combine the VGA separate synchronization signals into SCART composite sync may suffice
A new connector has arrived for computers, peripherals and mobile devices.
USB –C, also be called as USB Type-C. It can consolidate the following functions over a single connector:
*Universal charging and power.
*External displays with display port.
*Other interface types, such as Thunderbolt.
The innovative USB -C connector can replace traditional usb normal connect port. Type-C is much more smaller, thinner and lighter. It can be plugged in no matter which way. It is more convenient for people and reduce chance of device port damage.
1. Locate the HDMI ports on all your devices. HDMI provides the best picture and audio quality out of all the different ways you can connect your devices. It is also the easiest way to connect devices, as you simply need to plug the cable into each device. If you have a receiver with enough HDMI input ports, and your TV has at least one HDMI input, you should be able to connect all of your devices to get the best possible quality from your home theater.
Most new receivers will have multiple HDMI inputs that allow you to connect all of your HDMI-capable devices, as well as an HDMI output for connecting to your TV.
2. Check what version of HDMI your TV supports. Check if your TV supports HDMI 1.4 ARC (Audio Return Channel). This allows the TV to send audio back to the receiver, which routes your TV sound through your home theater speakers. Most TVs made after 2009 support HDMI 1.4 and newer.
If your TV does not support HDMI 1.4, you will need to use a separate audio cable to connect the TV to the receiver. The best quality cable to use for this is a digital optical audio cable. Connect the digital optical cable from the TV output to the receiver input.
3. Connect your devices to your receiver inputs via HDMI. These could include DVD/Blu-ray players, game consoles, and more. If you have limited HDMI inputs, use HDMI cables for the most recent devices first, as they will benefit the most.
For example, if your receiver only has two HDMI inputs and you have a Roku, a PlayStation 4, and a DVD changer, plug the Roku and the PS4 in with HDMI, and use a component connection for the DVD player.
4.Connect the HDMI output on the receiver to the HDMI input on the TV. This allows the image from all the devices connected to your receiver appear on your TV. With HDMI 1.4 or newer, the audio signal from the TV will be sent back to the receiver, allowing the TV sound to be played through your surround sound system.
5. Use the receiver to switch between inputs. Ideally all of your devices will be routed through your receiver. This means that your TV can be set to the HDMI input that you plugged in from the receiver, and then you can switch between inputs using your receiver remote.
Since everything has been connected via HDMI, all the sound from your devices should go through your receiver’s speaker setup.
Most devices should configure automatically when they detect the HDMI connection, though you may need to tweak some settings for certain devices.
6. Connect your devices directly to your TV. If you aren’t setting up a home theater system, you can still plug your HDMI devices directly into your TV and then control the inputs using your TV remote. Most modern TVs have at least two HDMI inputs.
If you have more HDMI-capable devices than you do input ports on your TV, you can purchase an HDMI switch that will expand the number of available HDMI ports.
7. Enable HDMI-CEC. This is a protocol that allows you to control your HDMI-connected devices using one HDMI remote. Typically, you’ll want to use your TV remote to control your other HDMI devices. HDMI-CEC is enabled in your device’s settings menu, and will need to be enabled for each device that you want to control.
HDMI-CEC is called different things by different companies, including Anynet+ (Samsung), Aquo Link (Sharp), Regza Link (Toshiba), SimpLink (LG), and more. Refer to your TV’s manual for more information.

USB 3.1 is based on the latest USB transmission specification. The new USB 3.1 interface will be make bandwidth doubled and speed improved to 10GBP,
At the same time the encoding rate also increase again.
While new USB 3.1 is use of 128b/132b encoding, but in the 132b data, only use 4bit as checking code, and the transmission loss rates have sharply fallen down 3%(4/132).so the USB 3.1 not only increase the bandwidth, but also the transmission efficiency also increased more. Compared to 5V/0.5A for USB 2.0.
USB 3.0 provides 5V/0.9A power. But people still hope can supply stronger power capacity. Therefore USB 3.1 let the highest standard for power supply increase to 20V/5A, and the power have reached 100W.
USB 3.1 is very good, but you also need to pay attention to the USB3.1 and USB Type C are two different things. Strictly speaking, USB 3.1 is a transmission standard, but the USB Type C is a kind of port standard. USB 3.1 total have three port standard. Respectively is a USB Type A, USB Type B(Micro USB) and the latest USB Type C.
USB 3.1 and USB Type C are no absolute relevance between them. You must Know that USB Type C port may not represent its support the USB 3.1 standard.
While USB 3.1 standard also may not is the USB Type C port.
Please must pay attention to it when you choose and buy them.
USB is an external bus standard for the specification of computer and external device connectivity and communications. USB interface support equipment features plug-and-play and hot-swappable.
USB interface can be used to connect as many as 127 kinds of peripherals, such as mouse, modem and keyboard. USB since the introduction in 1996, has been successfully alternative serial and parallel port, and today a large number of personal computers and intelligent devices will be assigned one of the interface.
- USB version
The first generation: USB 1.0/1.1 transfer rate for the maximum 12Mbps. Launched in 1996.
The second generation: USB 2.0 transfer rate up to the maximum 480Mbps. USB 1.0/1.1 and USB 2.0 interfaces are mutually compatible.
Third Generation: USB 3.0 maximum transfer rate of 5Gbps, downward compatible with USB 1.0/1.1/2.0
- USB applications:
With the rapid development of computer hardware, peripherals, more and more keyboards, mice, modems, printers, scanners already known to all, digital cameras, MP3 players one after another, so much equipment, how to access a personal computer? USB is generated based on this objective. USB is a computer peripheral device is connected so that the standardization of a single interface, the specifications are from Intel, NEC, Compaq, DEC, IBM, Microsoft, Northern Telecom established contact.
USB is the English acronym for Universal Serial BUS. It is not a new bus standard, but it is used for the PC field of application interface technology.
USB was jointly proposed in the end of 1994 by Intel, Compaq, IBM, Microsoft and other companies. But untill recently, it has been widely used.
From November 11, 1994 version of USB V0.7 released later, USB version has gone through years of development, up to now has been developed for the 2.0 version of the current expansion of the standard computer interface. At present, the main motherboard is USB2.0 and USB3.0.
The USB version of the USB plug with a 4-pin plug as standard, the form can be used to daisy chain all of the peripherals connect up to 127 can be connected to external equipment, and no loss of bandwidth. USB needs of the host hardware, operating systems and peripherals support the three will work. The current motherboard is generally used to support the USB function control chipsets, motherboards are also equipped with USB interface socket, the socket and back in addition to, the motherboard also has USB pins is reserved, can be received through the connection box USB interface as a front in front of the convenience of the users (note that in connection to the motherboard manual to read and plans to connect must not be wrong then the damage of equipment). And USB interface can also be connected through a special USB drive to achieve two-plane interconnection line and can be extended through the Hub’s interface more. USB has a faster transmission speed (USB1.1 is 12Mbps, USB2.0 is 480Mbps, USB3.0 is 5 Gbps), easy to use, support hot-swappable, connect flexible, independent power supply, etc., you can connect a mouse, keyboard, printer , scanners, camera, flash disk, MP3 machines, mobile phones, digital cameras, mobile hard drive, external floppy drive light, USB card, ADSL Modem, Cable Modem, etc., almost all of the external equipment.
VGA Cable is used for transmitting analogue video signals from a VGA enabled device such as a projector or computer to a monitor some high definition televisions use this type of cable as well.
VGA stands for video graphics array,and it was a graphics standard used by IBM in its early PCs sold in the 1980s.
It’s characterized by 15pins on the plug in three rows of five. The plug also has two screws, one either side of the pins, that secure it into place in the socket. These screws have ridged edges,meaning they can be tightened and loosened by hand rather than needing a screwdriver.
Now it is used for PC,CRT/LCD/LED Monitor Display,projector etc.
The meaning for each pin
Your cable influences the charging speed of your device so even if you have the latest fast charger you might still not be charging at the fastest possible speed.
（1）What is the difference in cables?
From the outside many cables all look the same but on the inside, the construction is different and many cables have a slow only design. It all comes down to the wires ability to carry a fast speed.
（2）Inside a USB cable are 4 wires
The inside diagram of a USB cable.
- The white and green are for data .
- The red and black are 5v and carry the power for charging, these determine charge speed.
The amount of power your cable can carry is determined by the size of the 2 5V wires inside, a standard cable is 28 gauge and is capable of about .5A, this is the standard charge rate. A faster charger cable has larger internal wires (mostly 24 gauge) that can carry larger currents of 2A or more.
The size difference between a 28 and 24 gauge wire, easy to see here on the chart, but difficult to distinguish once it is made into a USB cable.
The relationship between gauge and total current is basic electrical physics, a wire is limited in the amount of current it can transfer therefore a larger wire can carry more current. This effect is even worse if you buy really long USB charger cables, you get a longer cable at the price of charging speed. Cable makers can make a low gauge cable cheaper than a fast one, so that is why fast charger cables are usually more expensive as the wires inside are larger. As most devices now are fast compatible I expect to slowly see all third party cables become faster. Currently, there are mostly slow standard cables in the market so if you are ready for fast charging, be sure to check your cables are also ready for your latest device and charger.
1. It is recommended to shut down before plug the HDMI cable, do not hot-
swappable HDMI cable. For ensurence of 100% safety of using HDMI, we
recommended you make sure you shut down the TV player or the HD player
before you plug the HDMI cable. For this the HDMI cable and HD equipment is
more secure and can avoid accidents.
2. HDMI connect TV and HD Player
Some users encounter some problems when they first using HDMI connection and high-definition television machine : When they plug the HDMI cable and open the HD player, there’s no any video signal. When suffering this kind of situation, please don’t panic and just check if there’re more than one HDMI interface. If it is, please select the correct interface.
3. Using different specifications of the HDMI HD line Due to the differences of the HD equipment, we need to select the suitable HDMI cable. Especially nowadays more and more families connect their computer with their LCD TV to watch movies. If the computer graphics card is not HDMI interface, but a DVI interface, then use a HDMI-DVI HD Cable is workable.
One of the lesser talked-about features of HDMI is its re-working of CEC, which was sometimes called CEC 2.0. This stands for Consumer Electronics Control, and lets one device send remote control-style signals to another over HDMI.
It’s effectively a stand-in for a proper universal remote control system – something that would be handy but is yet to turn up. With HDMI 2.0 you can – in theory – control up to 15 devices with the one remote. It was around in HDMI 1.4 but now it’s better.
No need to splash much cash on one of those expensive Universal ones but just need one remote control? Yes. Opting for CEC is also more attractive – in one sense – than using a phone’s IR transmitter as a universal remote (a feature of higher-end phones) as there’s no lengthy setup involved.
However, for it to really take off, the manufacturers of the boxes we’re going to control with CEC need to embrace the standard, and help people know it exists. Or we will never reach it at anywhere.
A lot of people got confused and were wondering if they suddenly needed to throw away their TVs in order to get on the latest tech trend when HDMI 2.0 was announced as a standard in late 2013.
As far as tech advancements go, HDMI 2.0 is a pretty friendly one. It’s as much a standard of software as hardware, and cables designed for HDMI 1.4 systems will work just fine with new HDMI 2.0 devices.
What you need to make sure is that both ends of your entertainment chain support the standard, for example, your TV and Blu-ray player. It’ll mean they’re geared up for the new standards we’ll dig into shortly. Some previously HDMI 1.4 hardware needs nothing more than a firmware update.
HDMI 2.0 itself isn’t really about resolution, but bandwidth. More bandwidth is what makes all of its new standards possible. HDMI 2.0 systems can transfer data at up to 18Gbps, up from 10.2Gbps in HDMI 1.4.
In terms we’re all more likely to get on with HDMI 2.0, 18Gbps is 2.250MB a second. Normal Blu-rays max out at 54Mbps, or 6.75MB per second.
With the arrival of HDMI 2.0, we’re one step closer to 4K Ultra HD
The High- Definition Multimedia Interface(HDMI) was originally launched 2002 to replace the ageing and bulky SCART connection.
HDMI has been through several iterations since then, the fifth of which is the newest version- HDMI 2.0. But what is it? What does it do that the current HDMI connections on the back of your HD telly dont’t?
What is HDMI 2.0？
Officially unveiled at IFA 2013 by the HDMI Forum, HDMI 2.0 is an improved standard for AV connectivity and the heir apparent to HDMI 1.4( released back in 2009). You’ll need an HDMI 2.3-compatible HD TV if you’re interested in watching the full range of 4K Ultra HD source material in the future.
Doesn’t HDMI 1.4 support 4K Ultra HD?
Yes. But there’s a problem. As its name suggests,”4K” is four times the resolution of 1080p Full HD and it actually requires more bandwidth than the current HDMI 1.4 spec can handle.
While HDMI 1.4 has a throughput of 10.2Gbps, it’s only enough to support a 4K resolution of 3840×2160 pixels at 24,25 and 30Hz or to display full 4K(4096×2160 pixels) at 24 Hz. The 2160p24 and 2160p30 formats might be good enough for movie playback, but they fall short of the 50/60Hz required for 4K TV broadcasts and future Ultra HD gaming.
HDMI 1.4 also only supports 8-bit color at 4K. HDMI 2.0 improves upon this, offering 10 to 12-bit colour depth at Ultra HD resolutions.
We can see a lot of cables in our life.They changed our life and help us link the colorful world tightly. These cables make our life more convenient quickly connect virtual world.
Let me take a example, one of the most common cable is HDMI cable.It needs only a HDMI line to transfer audio signals instead of so many wires. At the same time, as wireless digital/analog signal or analog/digital signal transfer can achieve a higher quality of video and audio transmission.
HDMI technology can not only provide clear picture quality, but also simplify the installation of a home theater system. Because it needs only one wire for both Audio and Video. HDMI Ethernet channel, audio return channel, HDMI 3D function, 4 k x 2 k video support, bring human more visual color space.
HDMI cable has been widely used in our life such as set-top box, DVD players, personal computers and TV game etc.
A HDMI cable has the following components:
1. Conductor: Because of the good conductivity of Copper, most of the cables use it as the conductor. So as HDMI cable. But because the cost of cooper is high, only High-end cables use silver plated or copper wire, common cables use tinned copper.
2.Shield: Woven tinned wire woth production equipment, shielding efficiency of high-grade cables can reach 95%, while general cables can only reach 80%.
3. Twisted: HDMI cable twisted process is mainly for preventing interference. There are some special processes, such as: twisted, total twist, wings of aluminum foil,ect.
4. Insulation: Including insulation of the copper wire and the external insulation (outer jacket). Copper wires insulating material is common use FO-PE. and also use a special foam process.Outer jacket usually use PVC material.
5. Magnetic ring: Some HDMI cable will with a magnetic ring, but this is not a necessary part, neither not a standars to determine the quality of HDMI. Magnetic ring can reduce the interference to a certain extent, but if a HDMI is good enough, it is not necessary to use a magnetic ring.
Sometimes we need to extend a external display for our HDTV or PC, so to know learly about the differences between VGA, DVI and HDMI is the precondition to purchase a suitable display.
1.VGA: 15pin video interface, mainly used for the old computer output. It output and transmit analog video signals, so when using VGA as a video interface, it needs to experience one time “digital to analog” and one time “analog to digital”. Signal loss, so the video would a little obscure.
2. DVI: There are 2 standards for DVI interface, 24+1 pin and 24+5 pin. Actually there’s no any difference between these two interfaces. DVI interface is a digital signal transmission, it can transfer large-resolution video signal and no need conversion when connect computer graphics to the display, so the signal not lost.
3.HDMI: HDMI transmit digital signals as well. Therefor for the quality of the video, it’s almost the same by using DVI and HDMI. HDMI interface can also transmit audio signals. So if the monitor is with a Audio in addition to the display function, HDMI interface can transfer both video and audio to it simultaneously. There have three types of HDMI connectors, A type, C type, and D type. They are with the same function, the only difference is the size of the interface.
The popularity of computers and the rapid development of science and technology make many computer peripherals out, and there’re a variety of ways to connect computer peripherals .Now let’s review the computer peripheral cables.
1. HDMI Cable: The cable that used for computer video output.Now almost all computer graphics card support HDMI inperface.
2.USB to Typr-C: A new generation of USB transmission interface, is a standard of USB3.0 and widely used in mobile phones and flat products.
3.DVI cable: DVI is a replacement of VGA, and has a higher resolution support and better imaging results than VGA.
4. VGA cable: the mainstream display video input interface currently. The current display video input cable, in addition to VGA, that is DVI.
5.Power Cord: For power supporting.
6.AV audio cable: mainly used for computer and computer peripherals connection , input audio to the audio equipment from computer.
AWG is the short of “American Wire Gauge”,the specification of the wires.
AWG is the way to indicate the diameter of the wire, it’s the function of the conductor thickness(inches).The diameter of 24AWG is about 0.511mm. The digital before AWG expresses the number of the holes that the conductor need to gone through before shaped, the bigger digital, the more holes, so the smaller diameter.
The thicker conductor has better physical strength and lower resistance. But as the conductor is thicker, it needs more Copper to make it, and will make the cable heavier, harder to install, so that the price will more expensive.
The challenge of cable design is to use wires with as small diameter conductor as possible (to reduce cost and installation complexity) while ensure maximum capacity of the wire under the necessary voltage and frequency at the same time.
HDMI high-definition engineering wires, according to the length of the wires, can be divided into different specification.If you want to learn more information about this pls contact us.
Firstly, although a HDMI Cable is usually thicker and harder than other cables, it should not be too hard. Because if it is too hard, it makes the cable hard to bend and may cause poor contact situation because of easy to slip or tilt when connecting. Also, almost all higher quality cables use BC material, that’s why it should not be a hard cable. Therefore, we should pay more attention to those HDMI Cables that look and touch hard.
Secondly, not only those hard HDMI cables are not good but also those too soft and too thin. If the cables are too soft and too thin, it certainly means the materials are reduced a lot when producing, and maybe the shield layer was lost as well, so that the transmission effect will be very poor for such a cable.
In addition to the wires quality, we should not ignored the connector of the HDMI cables when purchasing. For transmission effect, the best material, of course, is the gold, the next one is silver, and then is copper. But as a result of the high cost of gold and silver, there almost no pure gold and silver wires in the market.So that in order to strengthen the transmission effect of copper wires, people use gold-plated and silver-plated a lot. Especially the connector part, it may be inserted and pulled oftenly, so most of the excellent quality HDMI cable has a gold-plated connector.
Lastly, HDMI cable shielding and Anti-jamming processing is also very important. Generally, a HDMI cable with a better shielding, is a bit thicker and harder but flexible. In addition, if there’re two magnetic rings at the two ends of the cables, it helps the cables enhance the anti-interference. As for the woven mesh that covers over some of the cables, it’s not so important because it’s just the nylon material and only use to make the cables good-looking and wear resisting.
In short, we should choose a better HDMI cable from not only one point but from all associated information.
