  • 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: 8377517
    Abstract: A method of forming transflective LCD panel includes forming a compensation material having reactive liquid crystal monomers, thermal initiators and a solvent on a first substrate. Then, a first heating process is performed on the compensation material to remove parts of the solvent and then a photo-polymerizing process is performed, and parts of the compensation material disposed in a reflective region are turned into birefringent zones. Moreover, a second heating process is performed, in which the first substrate is kept in a predetermined temperature for a predetermined time, and thereafter nitrogen gas flows in to the chamber to form a non-oxygen condition. Accordingly, parts of the compensation material disposed in a transmission region are turned into isotropic zones. The predetermined temperature of the second heating process is higher than the clearing point of the reactive liquid crystal monomers.
