The display module 3 is provided with a touch and display driver integrated chip 40 (TDDI, Touch and Display Driver Integration), which integrates the touch chip and the display chip into a single chip. The touch and display driver integrated chip 40 generates touch point reporting data based on the sensed user input information; the MCU module 20 is also used to receive the touch point reporting data, perform protocol transcoding, and output it to the host computer 1.

[0018] Here, the receiving module 10 specifically includes a low voltage differential signal interface LVDS RX, which has four built-in channels and can support VESA / JEIDA format and 8 or 6 bits mode. Correspondingly, the output module 30 specifically includes a mobile industry processor interface MIPI TX, which has four built-in channels and can support up to 1.2 Gbps / lane.

[0019] The user performs a touch operation on the display module 3, and the touch and display driver integrated chip 40 senses the user's touch operation and generates touch point reporting data according to the user's output information, and transmits the touch point reporting data to the SOC chip 2 for protocol transcoding and then outputs it to the host computer.

[0020] In the embodiment of the present application, LVDS is used to transmit display image data. After the display image data is received and internally processed by the SOC chip in the bridge-type image processing system, it is transmitted to the display module via MIPI to display the image. At the same time, the input information generated by the touch of the display module can also be transcoded and transmitted to the host computer via the SOC chip protocol to obtain user instructions.

The instruction signal here can be a control instruction for processing the video data. The serial peripheral interface 201 sends the instruction signal to the data path control module 202. The data path control module 202 processes the video data based on the instruction signal, and caches the processed first result in the first memory 203.
