新型大屏幕运动型显示屏显示技术研究

Display techology for motile display screen of new big screen

针对制约运动型发光二极管显示屏发展的主要因素——使用发光二级管的数量多而引起成本高的问题,对其时空分割原理和总体设计方案做了简单的阐述,重点介绍了用FPGA设计的运动型显示屏的电子线路及显示部分中各部分的功能和工作原理,及将视频信号转换为发光二极管显示的过程。通过运动的方式,使1个发光二极管代替几个发光二极管发光,利用人的视觉暂留达到显示信息的目的。实验结果证明该方法制造的运动型显示屏能正确显示传送的信息内容的同时,节省大量的发光二极管,使总体造价大大降低。

LED used in a mobile LED display screen increases the cost, which is a reason why mobile LED display screen develops slowly. A simple introduction of the theory of space-time segmentation and the overall design solution are presented, focusing on the function and working theory of the motile display screen＇s electronic circuitry and display part with FPGA. The procedure of how the LED displays screen transfers the video signals into LED display is also introduced . Through the mobile way, one LED could play the role of several LEDs. And because the signals last a period of time in the vision of human beings, the information could display to the readers. The results show mobile LED display by this method could display information correctly, as well as save lots of LEDs thus lower the cost tremendously.
