【摘要】：OLED具备自发光、不需背光源、对比度高、厚度薄、视角广、反应速度快、可用于挠曲性面板、使用温度范围广、构造及制程较简单等优异特性,被认为是下一代的平面显示器新兴应用技术。目前OLED的驱动大部分都是基于STM系列ARM芯片和传统FPGA芯片。为适应Xilinx最新平台Zynq的人机交互需要,提出一种基于Zynq的OLED驱动设计方法。文章阐述了OLED的特性和SPI控制方式,给出了设计流程和硬件电路图。利用Zynq的PL部分完成了OLED驱动的IP核,利用Zynq的PS部分实现了OLED的驱动程序设计。通过AXI总线实现PL和PS的通信。最后通过测试程序,实现了字母、数字和点阵图像的实时显示。解决了基于Zynq器件在广电仪器和电力仪表仪器中人机交互的工程技术,具有集成度高、可移植性强和通用性好等优点。
[Abstract]:OLED has many excellent characteristics, such as self-luminous, no backlight, high contrast, thin thickness, wide angle of view and fast reaction speed, which can be used in flexible panel, wide temperature range, simple structure and process, etc., so it is considered to be a new application technology of the next generation planar display. At present, most of the drivers of OLED are based on STM series ARM chips and traditional FPGA chips. In order to meet the needs of human-computer interaction of Zynq, the latest Xilinx platform, a OLED driver design method based on Zynq is proposed. In this paper, the characteristics of OLED and SPI control mode are described, and the design flow and hardware circuit diagram are given. The IP core of OLED driver is completed by using the PL part of Zynq, and the driver design of OLED is realized by using the PS part of Zynq. The communication between PL and PS is realized by AXI bus. Finally, through the test program, the real-time display of letters, numbers and lattice images is realized. The engineering technology of human-computer interaction based on Zynq in radio, television and power instrument is solved, which has the advantages of high integration, strong portability and good generality.
