In the existing display screen button, a liquid crystal display screen is installed inside, and a light guide glass is placed on the upper end. When the user presses the light guide glass, the pressing function is realized through the cooperation of a spring, a ball, and a dome switch in terms of structure. Internally, the nodes are closed, thus forming a closed circuit. The closed circuit will form a flowing current. After the detection circuit senses the current, it will convert the button operation into a digital signal and then transmit it to the control circuit of the display for processing, thereby realizing functions such as controlling the screen switching through the SPI bus; online updating of internal stored pictures and other complex functions through the SPI bus.
