数据压缩技术在LED大屏幕中的应用

APPLICATION OF DATA COMPRESSION TECHNIQUE IN LED DISPLAY

ＬＥＤ大屏幕作为一种较新的数字图象显示设备，随着其技术的发展，现在已出现了全彩色ＬＥＤ大屏幕．但随之而来的便是图象数据量的增加，给数据传输带来的很大压力．此文根据数据压缩技术的发展，结合ＬＥＤ大屏幕的特点。

With the rapid development of display technique, as a new digital image display device, LED display s color is being more and more opulent. Now there is the full color LED display which displaying color is as good as CRT, but this display s image data increases much. The increasing of data gives more pressure on the circuit of LED display , especially on the data transfer. Common solution is parallel transfer or increasing the transfer frequency. In this paper the application of data compression technoique in different LED displays was studied. Basde on the development of date compression technique and the features of LED display.
