大面阵显示器装表系统的设计与实现

Design and Realization of superposition system of large-area display

介绍了一种基于EP2C8视频装表系统的硬件设计与软件实现的方法,提出了一种新的系统装表方案,在简化了装表系统的硬件电路和软件设计的同时,提高了系统的可靠性,降低了功耗;并根据背景灰度值的不同,可以手动调节大面阵显示器的亮度,以适合全天候使用。本系统具有灵活性强、体积小、功耗低等特点。

The thesis presents a new type of hardware design and software realization based on EP2C8 video superposition system.The insufficiency of special-purpose superposition chip or compound superposition video system can be overcome.In this system,aiming-line and the information of distance and position which have been installed to the large-area display can move in single pixel;and besides,according to the different gray values of the background,it can alter automatically the gray value of itself to make a stark contrast.All this is what the existed systems cann＇t achieve.This system has the characteristics of high flexibility,small size and low power consumption.
