[0037] Currently, for the touch display screens of the OPi5 series main boards of the Orange Pi on the market, most of them mainly use HDMI interfaces. The display screens using HDMI interfaces need to connect at least two signal lines to the main board interface, one HDMI cable and one USB cable. The HDMI cable is used to transmit video signals, and the USB cable is used for power supply and transmission of touch data signals. Since the cable volumes of the HDMI cable and the USB cable are relatively large and the hardness is relatively high, it is difficult to design the product shell, which is not conducive to the miniaturized design of the product, resulting in the problem that it is difficult to integrate the touch display screen based on the Orange Pi. Therefore, the embodiment of this application provides a portable touch display screen based on the Orange Pi main board.
