摘要: 介绍了一款全彩无源OLED模块的驱动接口电路及驱动程序的设计。系统采用ARM7系列的LPC2138为控制核心，分别设计了电源电路、下载电路、复位电路和接口电路，并向全彩无源OLED模块提供数据信号和控制信号，从而实现了分辨力为128128，65103色的动态全彩图片显示。设计了基于ARM7内核的OLED驱动电路实验系统，可显示红、绿、蓝单色以及全彩图片，为中小尺寸OLED提供了一种低成本、低功耗的单芯片解决方案。Abstract: The paper introduces the design of driving circuit, reset circuit, download circuit, interface circuit and driving programs of the full-color passive OLED(organic light emitting device) module in the display system. The system adopts the LPC2138, family of ARM7-core, to control the OLED module. The data and control signals are provided by LPC2138 in order to realize a resolution of 128128, 65103 dynamic full-color display. Experiment results show that the system can display red, green, blue and full-color pictures, provide a low-cost, low-power and single-chip solution for small sized OLEDs.
