一种高清数字视频近眼立体显示系统设计
|
摘要
根据微型AM-OLED显示器的技术原理,提出了以双HDMI接口为视频输入接口、PIC16F1825为MCU控制芯片,以及双微型AM-OLED为显示器的立体显示系统的电路设计方案,主控芯片通过IIC串行总线对各模块寄存器进行配置。利用人眼的双目视差成像原理,通过配置HDMI解码芯片ADV7611和AM-OLED微显芯片的寄存器,使交错隔列立体视频源的奇数列和偶数列分离,视频源的奇数列和偶数列分别显示在左右眼相对应的AM-OLED显示器上,最终实现了立体显示。经测试,验证了系统方案的有效性。
According to the principle of AM-OLED micro display technology,we propose a circuit scheme of three-dimensional display system with dual HDMI interface as the video input,PIC16F1825 as the MCU and dual AM-OLED as the micro display.The register of each module is configured through the IIC serial bus by master controller.Stereo display is realized by using the binocular parallax principle of the human eye.By configuring the controls parameter of ADV7611 and SVGA050micro display,the odd and even column of stagger stereo video source is separated.The odd and even column of stereo video source is displayed on left and right AM-OLED micro display,which is corresponding for left and right eyes.Finally,the stereo display is realized.The development of the stereo display system measurement verifies the effectiveness of the proposed scheme.
