摘　　要：本文介绍了一种针对彩色CRT型的背投影电视墙单元亮度均匀性的电路校正方法,并讲述了电路的实现方法及原理,解决了对于CRT投影电视墙亮度均匀性差的问题。本方案的优点在于不损失CRT电视墙总亮度的同时,电路较为简单并容易实现,对于不同的CRT背投电视墙可以实现自适应的校正过程。In the article, a circuit correct method is introduced that how to improve illumination distribution for single unit ofcolor CRT projector video-wall, and the problem of the poor of illumination distribution is resolved fairly. The advantage of thisplan is thatthe total illumination of CRT projector video-wall will not loss, and the circuit is enough easy to achieve it. Moreover, auto-adjustment can be accomplished for different CRT projector video-wall.
