基于ARM的OLED显示系统设计

The Design of Display System for OLED Based on ARM

由于传统的LCD具有显示角度过小等缺点,设计了OLED(有机电致发光显示器)显示控制电路,采用周立功开发的T2387I工控模块为处理器,加上外围电路对256×64点阵,具有16级灰度的单色OLED显示进行控制,并用可控的电源芯片实现对OLED的上下电顺序控制。通过字模提取软件提取所需显示汉字的字模数据,采用C语言编程实现OLED的显示。

A kind of display controlling circuit for OLED（Organic Light Emitting Diode display）is designed because of the display angle of LCD.The T2387I module,which is developed by Zhouligong Co.,Ltd,is used as the processor in this system.The system can control the OLED which contains 256×64 dots matrix and 16 gray scale levels.Furthermore,the power chip with enabled port is used to achieve control of OLED＇s power up/down sequence.The character die of Chinese Character can be get by a kind of making code software.C Language is used to write program to achieve OLED＇s display.
