Transflective Liquid Crystal Display

摘要

A pixel of a transflective liquid crystal display panel having a controllable backlight comprises an array of sub-pixels and a color substrate with an array of colors corresponding to the array of sub-pixels, the array of colors comprising transmissive colors and reflective colors. The color substrate transmits at least one wavelength of light corresponding to the transmissive colors in the array of colors when the controllable backlight emits a first predetermined light level and, from substantially the same area in the color substrate, reflects at least one wavelength of light corresponding to the reflective colors in the array of colors when the controllable backlight emits a second predetermined light level. The transmissive colors may be primary or secondary colors, and the reflective colors may be primary or secondary colors. The primary colors may form the top row of the array of sub-pixels and the secondary colors may form the bottom row of the array of sub-pixels, or at least one of the primary colors and at least one of the secondary colors may form the top row of the array of sub-pixels, and at least one of the primary colors and at least one of the secondary colors may form the bottom row of the array of sub-pixels.

主权项

1. A pixel of a transflective liquid crystal display panel, the display panel having a controllable backlight, comprising:
an array of sub-pixels; a color substrate with an array of colors corresponding to the array of sub-pixels, the array of colors comprising transmissive colors and reflective colors, the reflective colors being the complement of the transmissive colors, the color substrate transmitting at least one wavelength of light corresponding to the transmissive colors in the array of colors when the controllable backlight emits a first predetermined light level and, from substantially the same area in the color substrate, reflecting at least one wavelength of light corresponding to the reflective colors in the array of colors when the controllable backlight emits a second predetermined light level; and wherein the transmissive colors are primary or secondary colors and the reflective colors are primary or secondary colors.
