Abstract
A transflective liquid crystal display includes a plurality of pixels. Each pixel includes a plurality of primary color sub-pixels and a brightness-enhancing sub-pixel. The reflective region of the transflective liquid crystal display is formed only on the brightness-enhancing sub-pixel.
Claims22
A transflective liquid crystal display, comprising:
- a plurality of pixels, each of the pixels comprising multiple primary color sub-pixels and a brightness-enhancing sub-pixel, wherein the reflective region of the transflective liquid crystal display is formed only on the brightness-enhancing sub-pixel.
A transflective liquid crystal display, comprising:
- a first substrate on which light-filtering regions and transparent light-transmitting regions are formed, the light-filtering regions being spread with color filters having different colors, and the transparent light-transmitting regions containing no color filters;
- a second substrate opposite to the first substrate and divided into a first region overlapping with the light-filtering regions, a second region overlapping with the transparent light-transmitting regions, and a third region that is the remaining region of the second substrate except for the first and the second regions;
- and
- a liquid crystal layer interposed between the first and the second substrates;
- wherein the reflective region of the transflective liquid crystal display includes at least a portion of the second region and excludes the first region.
A driving method of a transflective liquid crystal display, the transflective liquid crystal display comprising a plurality of primary color sub-pixels and brightness-enhancing sub-pixels, wherein the reflective region of the transflective liquid crystal display is formed only on the brightness-enhancing sub-pixels, the driving method comprising the steps of:
- recognizing whether the display mode of the transflective liquid crystal display during operation is a reflective mode or a transmissive mode;
- and
- sending image data having a voltage smaller than the liquid crystal threshold voltage into the primary color sub-pixels when the display mode during operation is the reflective mode.
