HDMI Connector have 5 types of connectors such as Type A, B, C, D, and E for different applications. HDMI ports come in different sizes, which include micro-HDMI and mini-HDMI.
HDMI ( High-Definition Multimedia Interface ) is a type of connector or cable capable of transmitting high-quality and higher bandwidth audio and video streams from a source. HD signal is the type most frequently used to transfer audio and video content from one device to another. When it comes to digital audio-video interface, it is never too hard for us to think of HDMI, a household port on every display device. To put it another way, you can easily find it in your daily life, such as Liquid Crystal Television, desktop, projector and even laptop, for all of these are always marked with the symbol of HDMI. Gradually, this port has become one of the most important and indispensable standards, and played a big role in transferring digital video signal. Have you ever used HDMI cable? And how much do you know about HDMI port? If you only have a vague notion of it, follow Elecife and figure out the whole aspects. Today, we will expound something about its types first.
Commonly-used HDMI port nowadays
Before that, although HDMI is well-known to everyone, it’s still necessary to make its basic concept clear. HDMI(High Definition Multimedia Interface), designed by HDMI Founders, is a kind of proprietary connector that can transfer audio and video signal simultaneously, which is mainly applied in the field of audio-visual devices and home appliances. Compared to the ordinary VGA interface, it is unparalleled, just like the telephone line broadband and optical fiber, whose data transmission ability is extremely different. Well, without further ado, it’s time to get down the business.
It is recognized that there are five types of HDMI Connector. In order to classify them clearly, HDMI Forum stipulates that Type A/ B are defined under the HDMI 1.0 Specification, Type C/ D are under the 1.3 Specification, and the rest two types are under the 1.4 Specification. Next, let’s have a close look at these five different types.
*Overview of HDMI connector types
HDMI Type A
It is so-called the standard HDMI connector that mostly can be seen on the market. Featured with 19 pins, HDMI Type A(male port) owns the width of 13.9mm and the thickness of 4.45mm. For female port, it’s 14mm*4.55m. It is obvious that HDMI Type A connector is a flat “D” type with a wide top and a narrow bottom. Importantly, Type A is allowed to carry several ranges including Standard-definition, Enhanced-definition, High-definition, Ultra-high-definition and 4K. Due to its wide application, you can notice in a breeze that this type is often used in 99% existing display devices, like TV, DVD player, and PC etc.
HDMI Type B
The second one turns to the most rare type, that is, HDMI Type B(also named dual-link or DVI-I connector). Compared with Type A, it has a bigger physical structure with the size of 21.2 mm×4.45 mm. But the basic shape does not change a lot. Accordingly, the number of pins increases to 29 and the transmission bandwidth is doubled. Based on these features, Type B is just available in some professional occasions for the use of super high-resolution displays(Wide Quad Ultra Extended Graphics Array 3840 × 2400 as an example). However, it is regrettable that this type is hardly used in any products on account of the limit of low-efficient Time Minimized Differential Signal.
HDMI Type C
Born for small devices, HDMI Type C is called Mini-HDMI(not an official name) as well. Though it has the same 19-pin structure as Type A, it is smaller and features with single row of pins. Type C can be said the reduced version of standard HDMI owing to the 10.42mm*2.42mm body. Therefore, its applicable scope is limited to the portable devices, such as Digital Still Camera, Portable Media Player and tablet. It is worth mentioning that Type C connector enables to be connected to Type A connector, which an extra Type A-to-C cable or adapter is needed.
HDMI Type D
With similar 19-pin configuration, HDMI Type D is narrowed to approximate size of micro USB, which measures 5.83mm*2.20mm and becomes much more smaller than Type C, so that it can be referred as Micro-HDMI connector. It is out of question that this type is generally adopted in the small mobile devices. Cellphones, MP4 and other devices with the pursuit of thin and light design are the common outcomes by applying HDMI Type D port. What’s more, Type D is able to bring the maximum 1080P resolution and 5GB transfer speed in the meanwhile.
HDMI Type E
This is the special type of all HDMI connectors. You can find HDMI Type E in the car and consider it as automotive connector. Likewise, it also has 19 pins, but the difference lies in a locking tap design that is added on the place where the cable is connected, so as to ensure the reliability of connectivity. Because of the instability of the environment of the vehicle, Type E functions well in automotive connection system with various powerful features, covering shock resistance, moisture resistance and large temperature tolerance range.
That’s all for HDMI connector types. Since you had a smattering of it right now, you must have confidence in absorbing other knowledge of HDMI port. Of course, more can’t-miss information is always in the next post. Keep focus on Elecife and get what you want to know in a flash.
