摘　　要：驱动控制电路是展示显示屏优良特性的重要部分,可编程逻辑器件FPGA具有功能灵活性,适合于高性能的视频和图像应用。文章利用液晶驱动芯片,模拟视频解码芯片和Altera公司的低成本CycloneFPGA器件,设计了一种新的针对13.2cm(5.2in)(320×3×240)彩色有源OLED屏的视频显示驱动控制系统,可以实现各子像素64级灰度显示。详细介绍了系统组成和FPGA各逻辑模块工作原理,并在QuartusⅡ软件开发环境下对各模块进行设计和仿真,仿真结果表明该系统可以实现彩色AMOLED屏的驱动控制。由于FPGA的可编程特性,可方便地设计用于更高分辨率显示屏的驱动控制电路。该系统可作为一种测试OLED显示屏特性的平台。Driving and control circuit is an important part of display system. FPGA is versatile and suitable for video display. A new driving and control system for 13.2 cm（5. 2 in） （320 × 3 × 240） color AMOLED video display is designed. The system uses LCD driving chips, video decoder, and Altera＇s low-cost Cyclone FPGA device. It can implement a 64-level gray scale display. The composing of the system and the operating principle of each module in FPGA are represented in detail. The design and simulation of FPGA modules are constructed in the Quartus Ⅱ software development environment, which demonstrate that the design is realizable. With the programmable characteristic of FPGA device, driving and control circuit for higher resolution display can be easily designed. This system can be used as a performance-test platform for OLED display.
