Abstract

The invention provides a display device using millimeter-wave communication. The backplane is provided with a first millimeter-wave transceiver chip and the second millimeter-wave transceiver chip provided in the LED module is connected by a time-division multiplexing communication method. The function of the cable is replaced by the data exchange through the millimeter wave sending and receiving chip, so that the cable can be omitted. At the same time, the backplane and the LED module do not need to set the communication connection interface, which simplifies the structure setting of the backplane and the LED module; The output video interface circuit and the output audio separation circuit can realize the separate output of the audio signal and the video signal. It can be seen that the display device provided by this application can independently switch and separate the audio signal and the video signal, and also supports the audio and video fusion output. .

Description

technical field [0001] The invention relates to the field of display devices, in particular to a display device using millimeter wave communication. Background technique [0002] Existing display devices, such as picture splicer, also known as video wall control, video wall splicer, display wall splicer, etc., the main function is to divide a complete image signal into N blocks and then distribute them to N video display units (such as Rear projection unit) to complete a large-screen dynamic image display screen composed of multiple ordinary video units, which can support simultaneous access of multiple video devices. [0003] In the existing display device, the backplane and the display module are usually connected by communication lines, plus cables such as power lines and data lines, and usually one backplane is connected with multiple display modules, resulting in a lot of cables. The time is complicated, and the connector of the cable occupies a lot of space structure ...
