An OLED (Organic Light-Emitting Diode), which is an organic light-emitting diode, is an organic electroluminescent device having a multilayer structure. Compared with the traditional LCD (Liquid Crystal Display) using the principle of liquid crystal and backlight module imaging, OLED display module uses its own power-on self-luminous principle and structural design, making it lighter and thinner, high brightness, low power consumption, fast response, high definition, good flexibility, high luminous efficiency, can meet the many new needs of consumers for display technology. Nowadays, OLED display modules have been widely used in various industries to replace traditional LCDs, such as industrial automation equipment, medical equipment, consumer electronics products such as mobile phones, tablets, wearable watches, notebook computers, VR devices, etc.

Similarly, with the rapid development of electric vehicles, while continuously improving the performance of vehicles, major car companies have added new OLED display devices to enhance the driving experience of users, such as 2K or even 4K high-definition display of display devices, and novel designs such as instrument, central control and entertainment triple screen of vehicle-mounted systems. Among them, the central control display panel has gradually increased the use of OLED display modules to greatly improve the display resolution. In the communication protocol between the vehicle display module and the host, the LVDS (Low-Voltage Differential Signaling) and eDP (Embedded Display Port) protocols are used most. Compared with the traditional LVDS communication protocol, the eDP communication protocol has the characteristics of high single channel rate, low power consumption, low EMI interference, strong anti-interference ability of data transmission, etc., and is widely used to improve the communication efficiency between the OLED display module and the host.
