  • Patent number: 8842103
    Abstract: A method of driving liquid crystal display panel includes generating a plurality of eye data frames from a received frame of image data. A high data frame having a first liquid crystal rotating attribute and a low data frame having a lesser second liquid crystal rotating attribute are respectively generated from a respective two of the generated plurality of eye data frames. The high data frame and the low data frame are alternatingly used to drive the liquid crystal display panel according to a time division rate such that liquid crystal molecules are subjected to low and higher crystal rotating forces. In one embodiment, each pixel is space-divided into first and second sub areas having different distances between the first and second pixel electrodes, and the high data and the low data are time-divided and displayed on the pixel, enhancing visibility of the resulting image for different viewing angles.

  • Patent number: 8264778
    Abstract: A display substrate includes a base substrate, a reflection-polarization member, a first electrode, an insulation layer and a pixel wall. The reflection-polarization member is disposed on the base substrate to reflect and polarize incident light. The first electrode is disposed in a unit pixel area of the reflection-polarization member. The insulation layer is disposed on the first electrode. The pixel wall is disposed on the insulation layer and defines the unit pixel area. Therefore, the entire area of a unit pixel may be used as a reflective area or a transmissive area, and thus an aperture ratio may be improved in a reflection mode or a transmission mode.
