  • Patent number: 8957420
    Abstract: A thin film transistor (TFT) array substrate with few processing steps and simple structure is provided, wherein merely two patterned metal layers are required and a patterned planarization layer is adopted to separate the two patterned metal layers from each other and thereby reduce power loading. In addition, the patterned planarization layer has slots to form height differences so as to separate scan lines from common electrodes to further reduce the power loading.

  • Patent number: 8178288
    Abstract: A method for fabricating a display substrate is provided. A substrate is provided first. After that, an alignment film coating and an alignment treatment are performed to the substrate, and a layer of photoreactive monomer material is coated on the surface of the substrate after the alignment treatment. Thereafter, the layer of photoreactive monomer material is selectively irradiated by UV light in an exposed region, and the layer of photoreactive monomer material in an unexposed region is removed for liquid crystal molecules to have different pretilt angles in the exposed region and the unexposed region.

  • Publication number: 20100128025
    Abstract: A method of manufacturing and driving an optically compensated birefringence (OCB) mode liquid crystal (LC) panel is provided. In the method, the OCB LC panel is applied which is characterized that a closed structure region with HAN, VA or Bend property is around a display region of the OCB LC panel. Thereafter, the OCB LC panel is driven by a mode of multistage voltage variation. The mode of multistage voltage variation includes applying a high voltage to LC molecules in the OCB LC panel for transferring them to a bend or a VA state, decaying the high voltage to a low voltage above a bend state holding voltage of the OCB LC panel, and turning off the voltage to zero so as to maintain the configuration of LC molecules in the OCB LC panel in a ?-twist state.
