Background technology

Press, trend along with volume-diminishedization, computing and image processing real time implementation, internal memory high capacity and the transmission speed high speed of computer, cathode-ray tube display is substituted gradually and eliminates, display from giant displays such as desktop monitors to the portable terminating machine, all adopt LCD now, and because LCD can reach high brightness, low consumption electrically, requirement such as high-resolution, make it be expected to combine closely, become some indispensable in the daily life with the human lives.

Secondly, just with the present general specification of display interface on the market, the VGA joint of Cai Yonging (D-Sub just the most widely, DB-15), the VGA joint is the signal transmission means of a kind of simulation (AnAlog) in fact, and must convert to earlier analog signal after, can be presented on the LCD, and in the signal transfer process, can cause the depletion and the distortion of signal easily, and along with the progress of hardware technology, pursuit for pure digi-tal constantly promotes, so-called DVI (Digital Visual Interface) specification so develop again on the market, and with the transmission means of total digitalization, though signal from display card with digital mode send after, LCD also can directly receive with digital mode, minused transfer process once, nature has had a greatest lifting qualitatively what show.

On the other hand, in the past few years up to date, possessed the appearance of the LCD of screen sizes, then must need also big frequency range, high resolution could should be repaid, also new rate with more than color, at this moment, because the frequency range of DVI interface is limited, also thereby run into the bottleneck of development, so the formulation of new spec launches again thus, wherein the most key technology is exactly HDMI (High-Definition Multimedial Intergface) specification, improved at the shortcoming of display interface in the past, not only can directly transmit various unpressed image data, even also can transmit the data of sound, mainly be used in box on the machine, DVD player, Digital Television, monitor and projector etc., can transmit data mutually by this HDMI interface, and make video-audio data in transmission, all can present with the highest resolution, and frequency range can reach 5GBps, and the user can be viewed and admired with best quality.

In addition, with the present development of HDMI interface, also can be divided into two kinds of standard specifications of Type A and Type B, wherein Type A is 19-Pin, Type B is 29-Pin, and the specification of having only Type B could be carried voice data, the specification of its Type A 19-Pin, actual size is gone up some a little greatly than USB joint, but compared with VGA and DVI interface, sizable change has been arranged, and volume is little just to be meaned on its electronic product more than can being used in, and also can reduce the cost in the use relatively.
