蓝牙控制的OLED显示器件研制

Development of OLED display controlled by bluetooth

利用NPB为空穴传输材料,Alq3为电子传输和发光材料,研制成功结构为ITO/NPB(50 nm)/Alq3(60 nm)/Al(100 nm)的绿色发光OLED显示器件。运用STM32F103C8T6单片机模块、HC-06蓝牙模块、时钟电路模块、复位电路模块和电源模块构成无线蓝牙控制系统,引入OLED显示器件作为信息传输的人机界面显示模块,将用户要发布的信息通过手机APP编辑、蓝牙传输的方式传递到系统的显示面板。该面板的蓝牙控制系统由三个子模块组成:第一子模块是以51单片机为主的信息处理核心;第二子模块是蓝牙模块;第三子模块是安卓智能手机APP部分。整个系统具有多个优点:(1)OLED显示器件自发光、对比度高、厚度薄、广视角、反应速度快;(2)如果需要修改OLED显示器件需要显示的内容,只需要通过手机软件连接OLED显示器件,就能对其进行实时无线修改。

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.
