  • Patent number: 7061555
    Abstract: A dual mode liquid crystal display device comprising an upper substrate, a lower substrate and a liquid crystal layer between the upper and the lower substrate is provided. The lower substrate further includes a first thin film transistor, a second thin film transistor, a reflective electrode connected to the first thin film transistor, and a regional light-emitting source connected to the second thin film transistor. The first thin film transistor and its electrically connected reflective electrode and the second thin film transistor and its electrically connected light-emitting diode can be positioned inside two separate pixel regions or inside a single pixel region.

  • Publication number: 20040141106
    Abstract: A reflective liquid crystal display, having a liquid crystal display panel and a regional light source. The liquid crystal display panel has a plurality of pixels, and each of the pixels has a plurality of corresponding color blocks. The regional light source is directly incident on the liquid crystal display panel, such that the light generated thereby is impinging on a reflection layer of the liquid crystal display panel to cause reflection. The allocation of the regional light source includes scattered dots distributed over the color blocks corresponding to the liquid crystal display panel. Alternatively, the regional light source is allocated at an edge of each of the color blocks, or with an arrangement allowing the light to be incident uniformly.

  • Patent number: 6760087
    Abstract: A multi-domain vertical alignment liquid crystal display, having a substrate with a color filter, a liquid crystal layer and a thin-film transistor array substrate. The thin-film transistor array substrate has an array of thin-film transistors and pixel electrodes. The pixel electrodes have a plurality of protrusions and slits, and a dielectric layer with a planarized surface covering the pixel electrodes. Therefore, the dielectric layer on the protrusion is thinner. Or alternatively, the protrusions are exposed. The exposed protrusions being alternately arranged with the slits and the dielectric layer result in a planarization effect, and have the function of twisting the electric field generated by the pixel electrodes. The liquid crystal molecules are thus inclined towards different directions to divide the liquid crystal layer of the same pixel electrode into multi-domains.

  • Publication number: 20030222310
    Abstract: A method of fabricating a thin film transistor array substrate of a reflective liquid crystal display includes providing a substrate, forming a gate electrode on the substrate, and then forming a gate-insulating layer covering over the substrate. The method further includes forming a channel layer above the gate, forming a source/drain electrode layer and a reflective electrode over the substrate using one photolithography process. A protection layer is formed over the substrate.
