ABSTRACT:
A dual mode Liquid Crystal Display (LCD) capable of functioning in a dual mode, a monochrome reflective mode and a color transmissive mode. The present invention provides an LCD with color filters only over the transmissive part of a pixel, enabling readability in the ambient light. Yet another aspect of the present invention is the elimination of the black matrix mask used typically in color filter creation. Additionally, the present invention provides diagonal pixels to improve the resolution of the LCD in the color transmissive mode. Further, an aspect of the present invention enables the light to switch between two colors, while a third color (typically green) is always on, thereby, decreasing the required frame rate of the LCD, when used in the hybrid field sequential approach. Yet another aspect of the present invention is to create colors from the backlight, eliminating the need for color filters. Yet another aspect of the present invention is use of color filters over only the green pixels, eliminating the need for using additional masks for making the color filter array.
