The Characteristics of HDMI and DP interfaces for Industrial Display

Industrial display is used in industrial scenarios, it has the same structure and display output interface as ordinary display. Such as the general commercial display with HDMI, DP, DVI, VGA and other interfaces, industrial display is also some, the following Symtrue will give you a brief introduction to HDMI, DP interface knowledge, I hope to help you.

HDMI(High Definition Multimedia Interface) is a recently emerged Interface, which transmits all digital signals just like DVI. The difference is that HDMI can not only transmit high-definition digital video signals, but also transmit high-quality audio signals at the same time. The HDMI interface has the following features:

• HDMI1.4 standard, support the transmission of 4Kx2K resolution of the signal, with Ethernet channel, audio back channel, support 3D functions.
• support 4K resolution output, for TV and industrial display hd video display provides the basis.
• Support 3D function, can meet the requirements of 3D TV display signal transmission.
• HDMI support more than 30 color gamut space, under different standards, industrial displays can display vivid and bright colors.

HDMI is a digital interface that allows all analog connections (such as component video or S-video) to be converted from analog to digital without loss, thus providing the best video quality for industrial displays. The difference between digital video and component video is reflected in high resolution, especially in 1080P resolution. Digital video is clearer than component video, eliminating the poor softness and image trailing phenomenon in component video. Small, high-contrast, detailed images like text show the difference. HDMI interface in the display field has been widely used, HDMI interface mainly Micro,mini HDMI and standard HDMI interface.

Second, DP is short for DisplayPort and the successor of DVI. DisplayPort interface and miniDP interface developed by Apple are two common interfaces. Compared with DVI, DP interface has improved a lot, with a qualitative leap in bandwidth and customizability. The DP interface has the following features:

• External connection distance of DP interface can reach 15m, speed can reach 10.8GB /S, support 2560×1600 resolution and 30/36bit color depth.
• DP interface allows audio and video signals to be transmitted by one cable, supporting a variety of high-quality digital audio and video.
• In addition to the four main transmission channels, DP interface also provides a powerful auxiliary channel with a bandwidth of 1Mbps and a high delay of only 500us, which can realize a variety of functions.
• Apple miniDP interface, more powerful, not only small interface, and interface compatibility is good, just need to add a adapter can be. At present, DP interface is 1.3 standard, the speed can reach 21.6Gb/s, resolution support 4K, mainly applied to PC, this is why the current 4K display all use DP interface.

HDMI has the advantage of supporting many interface products, which is relatively mainstream at present. HDMI has the disadvantage of poor compatibility with PC, which does not support 3 or 6 multi-screen output. DP interfaces support 3 – to 6-screen output on PCS, but are not as widely used as HDMI because DP came out late. In short, DP is theoretically stronger and more advanced, but it came out late, has narrow application scope, and leans towards PC domain.

An industrial display, including HDMI, DVI, VGA, DP and other display output interface, through the above introduction and early introduction, I hope you have a new understanding and understanding of the industrial display interface. Only with a certain understanding of the display interface, we can buy suitable and satisfactory products when we choose and buy.
