Abstract

The invention provides a main control circuit board and a display device, the main control circuit board is used for the display device, and the main control circuit board comprises a first interface,a second interface, a first signal processing circuit and a second signal processing circuit; the first interface is connected with the first signal processing circuit, and the second interface is connected with the second signal processing circuit; and the first signal processing circuit is in communication connection with the second signal processing circuit. According to the technical scheme,transmission channels of 8K signals can be increased, and the cost of the display device is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a main control circuit board and a display device. Background technique [0002] The interface standards HDMI2.1 and DP1.4 supporting 8K (7680*4320) signals have been released, which shows that 8K TVs will soon be popularized in the homes of ordinary people. However, 8K TVs still have the following shortcomings: [0003] 1. Only supports single-channel DP1.4 interface to input 8K signal, does not support HDMI2.1 interface and other interfaces to input 8K signal; [0004] 2. The logic adapter board is required to complete the logical identification of 8K signals and 4K signals before the signals can be output to the 8K display for display. Contents of the invention [0005] The present invention provides a main control circuit board and a display device, aiming at increasing the transmission channel of 8K audio and video signals and reducing the cost of the display device. ...
