  • Patent number: 9557864
    Abstract: The present invention provides an array substrate, a liquid crystal display device comprising the same, and a method for forming the same. The array substrate comprises a gate line, a data line, a signal line and a pixel electrode formed thereon. The gate line intersects the data line to define a plurality of pixel regions in which the pixel electrodes are formed. Each of the pixel electrodes overlaps the signal line to form a first sensing capacitor and overlaps the gate line to form a second sensing capacitor.
    Type: Grant

  • Patent number: 8780019
    Abstract: The present invention relates to an electroluminescence display panel and a method of driving the same. The electroluminescence display panel comprises a plurality of pixels arranged in a matrix, each of the pixels including a red sub-pixel, a green sub-pixel and a blue sub-pixel. The blue sub-pixel includes at least a first blue sub-sub-pixel and a second blue sub-sub-pixel. In operation, the first blue sub-sub-pixel and the second blue sub-sub-pixel are alternately driven among frames.

  • Patent number: 7315339
    Abstract: A method for manufacturing an LCD includes the steps of providing a transparent substrate having a thin film transistor and a protective film successively formed thereon, positioning a shadow mask having a number of openings formed thereon to expose parts on which protrusions are to be formed on top of the substrate, forming protrusions by performing a sputtering process on the substrate using the shadow mask in such a manner that sputtering radicals pass through the openings and are selectively deposited on the protective film, removing the shadow mask, and forming a reflection electrode on the substrate including the protrusions.
