A green OLED display with ITO/NPB(50 nm)/Alq3(60 nm)/Al(100 nm) structure was developed by using NPB as hole transport material and Alq3 as electron transport and light-emitting material. STM32f103c8t6 singlechip module, HC-06 bluetooth module, clock circuit module, reset circuit module and power module were used to constitute the wireless bluetooth control system, the OLED display was introduced as the human-machine interface display module of information transmission, and the information to be released by the user was transmitted to the display panel of the system through the way of mobile APP editing and bluetooth transmission. The bluetooth control system of the panel consisted of three sub modules: the first sub module was the information processing core based on 51 single chip microcomputer; the second sub module was the bluetooth module; the third sub module was the Android smartphone APP part. The whole system had many advantages: (1) OLED display had self illumination, high contrast, thin thickness, wide viewing angle and fast reaction speed; (2) if the content of OLED display needs to be modified, it could be modified in real time and wirelessly only by connecting OLED display with mobile phone software.
