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

Due to having such excellent characteristics

self-illumination

without backlighting

high contrast

thin thickness

wide viewing angle

fast response

organic light-emitting diode (OLED) can be used for flexural property panel. At the same time

OLED is considered as emerging application technology of the next generation of flat panel display because of wide temperature range and relatively simple structure and process. At present

the OLED driver is mostly based on STM series of ARM chips and traditional FPGA chip. In order to meet the human-computer interaction requirement of "Zynq"

the latest platform developed by Xilinx

and a kind of method about OLED driver design based on the Zynq is put forward. In this paper

the characteristics of OLED and SPI control mode are introduced

and the design process and the hardware circuit diagram are given. The OLED driver's IP core is completed at the aid of the Zynq's PL part

and the OLED driver design is implemented at the aid of the Zynq's PS part. The communication between PL and PS is realized by AIX bus. Finally

the real-time display of letters

numbers and bitmap image are realized by the test program. It resolved engineering technology of human-computer interaction based on Zynq device in radio and television equipment and electrical instrument

with high integration

strong portability and versatility

etc.
