I believe that everyone from the era of CRT VGA interface to now LCD common HDMI, DP interface have some understanding. Today, based on the current situation of the interface, I guess the future trend of the display interface. Before we start, we should know that the higher the image quality and the finer the display of digital signal is, the higher the requirement for the interface bandwidth of the display. < p > < p > for example, when a 2K resolution and 165hz refresh rate E-sports display is connected with hdmi1.4 interface, the display can only display images with 2K resolution and 75Hz refresh rate in sRGB color space. < / P > < p > if you sacrifice the color of the picture, you can only bring a picture with a refresh rate of up to 2K resolution 144hz in ycbcr4:2:0 color space. In other words, due to the insufficient bandwidth of the display interface, the display panel performance cannot be fully utilized. < / P > < p > at present, 4K resolution displays have reached the price range of 1500, and the price is no longer an obstacle. The number of color displays has also greatly increased, and displays with color depth of 10bit can be found everywhere. In previous articles, we know that DVI-D interface has been replaced by HDMI and DP interface due to its weak compatibility, low transmission bandwidth and inconvenient use. There are two versions of HDMI interface at present. The bandwidth of HDMI 1.4 is low, which is only 10.2gdps, and only 30 frames of 4K video can be played. The bandwidth of HDMI 2.0 is higher, reaching 18gdps, and the playback frame rate of 4K video is increased to 60 frames. < p > < p > the ps5 and xboxseries x, which will be launched in the second half of this year, can output up to 4K / 120Hz pictures, while the RTX 3090 video card recently launched by NVIDIA can output 8K game pictures. HDMI 2.0 bandwidth alone can not meet these performance monsters, but these devices still choose HDMI interface. < / P > < p > due to the huge upgrade of HDMI 2.1, the bandwidth has been increased to 48Gbps, several times that of the previous generation. It can display images with 4K resolution and 120Hz refresh rate without pressure. < / P > < p > on the DP interface side, the highest dp1.4 currently has only 32.4gbps bandwidth, which cannot be compared with HDMI 2.1. Although the DP 2.0 standard supporting 80gbps bandwidth has been formulated, there is no product supporting DP 2.0. And DP interface is only used in the computer field. Compared with the HDMI used in flat panel TV, set-top box, game console and digital camera, the compatibility is very big. < / P > < p > from the current point of view, it seems that HDMI interface is in the lead in all aspects, quite dominating the interface market. But the winner is still unknown, because the DP interface still has a big trick to play. < / P > < p > at present, the type-C interface provided on the display is based on dp1.4 protocol. There are many functions of this interface, such as charging, data transmission, audio and video signal transmission. < / P > < p > electronic devices launched in recent two years, such as mobile phones, laptops, tablets, and even small items such as power banks and small fans, will carry this interface. It can be predicted that type-C will become the mainstream interface of electronic equipment in the future. < / P > < p > guess it boldly. If the form of DP interface becomes type-C in the future, only the display, motherboard and graphics card will be affected. And now DP interface computer dedicated this disadvantage, become the biggest advantage. In contrast, HDMI interface supports many devices, so it is not realistic to change the interface configuration easily. < / P > < p > although the devices that support the DP 2.0 standard have not yet come into the market, the standard has already been launched, and it is only a matter of time before the devices are launched. In addition, the type-C interface solves the problem of device compatibility, which seems to belong to DP interface in the future.
