介绍了两种RGBW排列结构的子像素着色算法，既保证了与传统RGB传统排列一样的分辨率，又提高了图像的亮度。图像处理过程包含两个算法：RGB到RGBW的转化算法和RGBW的子像素着色算法。RGB到RGBW的转化算法使图像获得新的RGBW数据，可在保证原RGB排列图像的色彩饱和度的同时提高图像的亮度，RGBW的子像素着色算法使图像更加逼真柔和，减少锯齿感。仿真结果表明，所提出的RGBW排列及着色算法可明显提高图像亮度。

Two sub-pixel rendering algorithms of RGBW arrangement structure are proposed. The algorithms can keep the same resolution as traditional RGB arrangement, and improve the image brightness. The image processing includes two algorithms: mapping algorithm from RGB to RGBW and sub-pixel rendering algorithm of RGBW. The image receives new RGBW data from mapping algorithm of RGB to RGBW, and the algorithm improves the image brightness and keeps the color saturation. Sub-pixel rendering algorithm of RGBW makes the image realistic and soft, and it can reduce jagged sense. Simulation results show that the proposed RGBW arrangement and rendering algorithm can significantly improve the image brightness.
