文章分析了目前应用于LED平板显示中的一种分辨率提升方法——亚像素复用技术，针对目前常见的三灯、四灯两种典型排布，通过软件仿真分析，指出亚像素复用技术可改善显示内容的锯齿状边界，同时使部分画面模糊。

The subpixel multiplexing technique for improving resolution in LED display currently was analyzed. Aiming at the two common arrangements, three lights arrangement and four lights arrangement, simulations and analyses were done to point out that the subpixel multiplexing technique could weaken jagged edges of displaying images, and cause obvious decline in some part of displaying images.
