基于单片机的全彩OLED驱动控制电路

Driving and Controlling Circuit for Full-color OLED Based on Single-chip Microcomputer

根据有机电致发光显示器件(OLED)的特性,以Philips单片机P89C51RD2为核心,集成了OLED驱动控制器SSD1338U2和外围电路,设计了一种OLED驱动控制电路。从系统硬件接口设计以及系统软件流程等方面介绍了该OLED驱动电路,结合硬件接口原理图,实现了分辨率为128×128、65 k色的全彩色图片显示。

Based on the characters of organic light emitting diode（OLED）, a kind of control circuits for OLED displays is designed. The single-chip microcomputer of the system is P89C51RD2 and the driver IC is SSD1338U2. The circuit is given by its hardware interface design and software flow, as well as hardware interface schematic. Using this circuit system, a resolution of 128X128, 65 k full-color image is displayed.
