Key Matrix Design Based on OLED Display Technology

In order to realize the hardware universal design of key matrix, function software custom settings and the number of keys can be expanded in the human-computer interaction scenario. The OLED display technology are studied, and the key matrix based on OLED display technology is designed. According to study the driving principle of OLED display keys, the circuit schematic diagram of LPC1788 controller, realizes the configurability of the software for displaying text and pictures. The key matrix design based on OLED display technology is stable, reliable, clear, versatile, beautiful in appearance, friendly in man-machine interface, and can be widely used in man-machine interaction system for keyboard requirements of vehicle, ship and airborne.
