为了将PC机上的视频源在双AM-OLED微型显示器上实现立体显示,设计了立体视频显示接口电路。对该系统所采用的人眼的双目视差原理和SVGA050微显芯片立体显示功能进行研究。针对AM-OLED显示器的结构与特点,提出了双VGA接口为视频输入接口、PIC18LF2550为MCU控制芯片,双AM-OLED微型显示器的立体显示系统的电路设计方案;介绍了母版和OLED板的设计以及主控器利用ⅡC串行总线对各模块寄存器进行配置。介绍了立体显示功能实现的原理和配置SVGA050微显芯片的立体功能控制参数的方法。实验结果表明,通过对开发的立体显示系统进行左右格式的立体视频源播放测试,实现了视频源在双1.27 cm(0.5 in)、800600分辨率SVGA050微显芯片上的立体显示。最后验证了基于AM-OLED微型显示器的立体显示接口电路设计方案的有效性。
In order to realize the function of stereo display on dual AM-OLED micro displays by playing the video source from computer
stereo display interface circuit is designed. The binocular parallax principle of the human eye and the stereo display function of SVGA050 micro display are investigated and applied.First
this paper proposed a circuit scheme of three-dimensional display system with dual VGA interface as the video input
PIC18LF2550 as the MCU and dual AM-OLED as the micro display. Then the design of the motherboard and OLED panel is introduced
the register of each module that is configured though the ⅡC serial bus by master controller is analyzed in this scheme. Finally
the principle of stereo display function and the means of configuring the stereoscopic controls parameter of SVGA050 micro display are introduced.Stereo display system has been tested by playing the stereoscopic video source of the left and right sides format. Stereo display function has realized on the dual AM-OLED micro displays which size is 1.27 cm(0.5 in) and resolution is 800600.The effectiveness of the proposed scheme of stereoscopic display interface circuit based on AM-OLED is verified.
