  • LCD with alignment layer having multiple alignments depending on color
    Patent number: 7064800
    Abstract: A gamma correction LCD panel and a fabrication of the same are provided. In the method, a lower substrate is firstly painted with a photo-alignment material. An exposing step is then introduced to have the photo-alignment material absorbed different amounts of light exposure so as to create various photo-aligning effects with respect to RGB pixel devices. The lower substrate is then assembled with an upper substrate and has an LC layer inter-filled. Upon such an arrangement, the LC layers with respect to RGB illumination can be thus provided with various transparencies for further adjust the RGB gamma curves individually.
