摘要
介绍了一种采用OLED技术的微型显示屏驱动接口电路的实现。根据实际系统性能要求与指标,从硬件和软件两个方面对驱动电路进行了设计,硬件电路体积为20mm×27mm,兼容NTSC和PAL制式,标称功耗为300mW;软件包实现显示初始化,软件IIC接口,组合键盘扫描等功能,同时可以方便地进行在线升级和维护。阐释了系统的硬件构成和软件流程图;最后介绍了实际的测试结果和应用。
A kind of display drive interface circuit for OLED microdisplays is introduced in detail. The circuit is configured in two aspects based on system performance demand： hardware and software system, hardware is sized by 20 mm×27 mm, compatible with NTSC and PAL mode, its nominal power is 300 mW; software initializes displays, simulates IIC interface, scans keys＇ matrix and so on. The structure of hardware and the flow chart of software are introduced in the paper. Finally, the results of experiment and its actual applications are given.
