微型OLED屏的显示控制技术研究
摘要
在消费类电子产品功能越来越丰富的条件下,显示器作为人机交互的界面已经变的越来越重要。随着科技的飞速发展,电路集成度的不断提高,人们对产品的多功能化,低功耗,便携等性能的要求也越来越高。微型OLED凭借自己出众独特的显示性能,在超便携多媒体设备,车载设备显示等领域成为理想的后端显示。本文设计了OLED微显示的一个通用模块,能够方便的集成到各种便携器件,顺应器件小型化,多功能化的发展趋势,为轻型热瞄具系统提供显示的参考方案。
本文首先比较了现在主流显示技术的优劣,介绍了微型OLED的一些基本概念和显示驱动原理,其中重点介绍了系统使用的EMA—-100080型的微型OLED屏的特性和工作方式,为后端驱动微型OLED显示屏提供理论依据。其次设计了系统硬件电路板,硬件电路以Altera公司的CycloneⅢ系列的FPGA为主要视频处理芯片,结合视频的A/D转换和数据的存储器实现对视频信号的处理。除此之外,系统硬件上还添加了三个RS-232串口接口,串口接口可以与不同的外接设备连接,外接设备通过串口与FPGA通信实现数据处理,增加了系统的多功能性和兼容性。最后详细介绍了PAL制式到SVGA制式的视屏转换方案,通过在FPGA上模拟12C总线,实现串转并,隔行变逐行,分辨率转换等视频转换操作,将前端的PAL制式视频信号转换成合适的SVGA信号在微型OLED显示屏上显示,更高分辨率的SVGA显示制式能够带来更优秀的显示效果。与此同时,外接设备GPS接收机和激光测距传感器通过串口与FPGA通信,在后端视频图像显示的固定位置叠加所需要的GPS定位信息和距离信息,在同一个显示器上能够多方位的观察周围的情况,对周围环境进行更精确的掌握。本文理论与实验相结合,在系统功能实现的前提下,尽可能的节省存储资源,为系统后续的功能增强提供便利条件。最后,协同系统的软硬件调试,在微型OLED显示芯片上实现了预期的显示效果。
In consumer electronics products more and more feature-rich conditions,Monitor as human-computer interaction interface has become increasingly important.With the rapid development of science and technology,the increase in density of circuit,customer has higher and higher requirement on the product of multifunctional,low power and protability.In this conditions,micro OLED with its exceptional unique display performance,becomes the ideal monitor in the portable multimedia equipment,on-board equipment display and other areas. This paper designs a common module of micro OLED display.The module can easily integrated into a portable device which complies with the device development trend for miniaturization and multi-functionality and provides the display reference scheme for light thermal weapon.
First of all,this paper compares the advantages and disadvantages of the present mainstream display technology,some basic concepts and display driving principle of micro OLED are introduced,and it puts emphasis on features and working function of EMA-100080 micro OLED display that using in the system, the theory basis are provided for driving micro OLED display.Then the system hardware circuit board designed,hardware circuit uses the FPGA IC chip of the Altera CycloneⅢseries as the main video processing chip,and combines with the A/D conversion and data storage to realize the video processing.In addition. The system adds three serial interface that can be connected to the external device which through the serial port to communicate with FPGA.In this way, the system increases more functional and compatibility. Finally in detail introduced the video conversion plan of PAL format to SVGA format.Through the FPGA to simulation I2C Bus,serial to parallel convert,conversion from interlaced scan to progressive scan,resolution conversion and so on to realize the video format conversion.High resolution SVGA display format can bring more excellent display effect.In the meantime the GPS receiver and laser distance-measuring sensor communication with FPGA through a serial port,at the fixed location of the video image display overlay location and distance information.So in the same monitor can have multiple observed around the situation and more accurate control to surrounding environment.In this paper,combining theory and experiment, as far as possible to save the memory resources under the precondition that the system function realization,providing convenient conditions for enhancement of follow-up system function.At last,after system of hardware and software debugging and then realizes the prospective effect in micro OLED display chip.
