多功能电视墙系统包括三个主要部分——微机控制部分、电源及驱动电路、多屏组合显示部分,本文详细介绍微机控制电路的设计方法。N×N电视墙微机控制部分的主要任务是将完整的活动画面实时分割成 2~N个块,由于活动视频图像变化很快,采样的数据很多以及超过60个特技功能,因此微机控制部分较复杂。其关键技术在于将数据图像信号以一定的方式适时地存入RAM及适时读出显示。
Multi-function video wall system consists of three main parts - computer control section, power and driver circuits, multi-screen combination display section, this article describes in detail the design of computer control circuit. N × N TV wall microcomputer control part of the main task is to complete the active screen is divided into real-time 2 ~ N blocks, the active video image changes rapidly, the sampling data and more than 60 special effects, so the computer control part of the more complex. Its key technology lies in the data image signal in a certain way in a timely manner into the RAM and timely read out the display.
