  • Patent number: 8552944
    Abstract: A pixel structure on a display panel comprises three sub-pixels where each sub-pixel can be arranged to a first transmissive region and a second transmissive region. The first transmissive region has a first transistor along with a first photo-resistant layer as well as the second transmissive region has a second transistor along with a second photo-resistant layer. The first photo-resistant layer and the second photo-resistant layer of different thickness or area are formed on a color filter. There exists a function relation between data signals received from the first transistor and the second transistor. Using these two data signals and combining the photo-resistant layers of different thickness or area will make each sub-pixel generate new level of brightness in gray scale and increase the number of displaying colors.

  • Patent number: 7636076
    Abstract: The pixel in a transflective color LCD panel of the present invention has an additional sub-pixel area. The pixel is divided into three or more color sub-pixels in R, G, B and at least one sub-pixel M. Each of the color sub-pixels is divided into a transmission area and a reflection area to display color image data. The sub-pixel M can be entirely reflective or partially reflective for displaying a further image data. Two or more algorithms are used to compute the further image data based on the color image data. A selector is used to select one of the algorithms for displaying the further image data. The algorithm selection can be used by a user or automatically selected according to the brightness of ambient light. The transflective LCD panel can be used in a reflective mode when the ambient light reaches a brightness level.

  • Patent number: 7564530
    Abstract: The pixel in a transflective color LCD panel of the present invention has an additional sub-pixel area. According to the present invention, a pixel is selectively divided into at least three color sub-pixels in R, G, B and a fourth sub-pixel M. Each of the color sub-pixels R, G and B is selectively divided into a transmission area and a reflection area. The fourth sub-pixel M can be entirely reflective or partially reflective. The color filter for use in the pixel comprises R, G, B color filter segments corresponding to the R, G, B color sub-pixels and a filter segment for the fourth sub-pixel. The filter segment for the fourth sub-pixel can be entirely colorless or partially colorless. Furthermore, one or more of the R, G, B color filer segments associated with the reflection area may have a colorless sub-segment.

  • Patent number: 7545467
    Abstract: A transflective liquid crystal display. A first substrate comprises a plurality of pixels, each pixel comprises a plurality of sub-pixels and each sub-pixel comprises at least one transmissive and at least one reflective regions. A second substrate is opposite to the first substrate, divided into a plurality of regions corresponding to the sub-pixels, and at least three of the regions are color regions and at least one of the regions is a fourth region. A first covering layer covers the first substrate, wherein the first covering layer in the transmissive region corresponding to the fourth region is substantially thicker than that corresponding to the three color regions, and the first covering layer in the reflective region corresponding to the fourth region has a thickness substantially equal to that corresponding to the three color regions. A liquid crystal layer is disposed between the first and second substrates.
