— This work combines a very simple resolution rescaling method, a well‐known RGB‐to‐YUV converting technique and a detection strategy into an optimized switchable mechanism in order to eliminate the problems of obvious zigzag profiles caused by the special layouts of transflective t RGB‐ t/r W TFT‐LCDs and the poor reflective gray‐level contrast ratio effected by the minimum white data in the transmissive RGB‐W + subpixel rendering algorithms. Finally, a transflective t RGB‐ t/r W TFT‐LCD is revealed not only to have no visible zigzag profiles and high visibility of reflective gray‐level contrast ratio, but also to have extreme reflectance and transmittance. The excellent optical performance of the proposed system makes it particularly suitable for single‐panel applications that need both high‐transmissive main displays and high‐reflective subdisplays.
