A new subpixel arrangement scheme called Checkerboard RB-G was proposed， which could further reduce the number of subpixels compared with most mainstream subpixel rendering schemes currently. Additionally， a subpixel rendering algorithm was proposed based on image binarization detection， which could solve the color deviation problem caused by Checkerboard RB-G. The test results showed that displays using the proposed scheme could achieve the same display resolution and similar display effects as those using traditional RGB stripe arrangement while reducing the number of sub pixels by 50%， significantly improving PPI and display quality.
