  • Publication number: 20090251646
    Abstract: An embodiment of the invention provides an array substrate for a liquid crystal display comprising a substrate and a gate scanning line, a thin film transistor, a data line, and a passivation layer on the substrate, the passivation layer covering the gate scanning line, the thin film transistor, the data line, and a through hole being formed in the passivation layer. A pixel electrode is formed on the passivation layer and comprises a transmissive part and a reflective part, the transmissive part comprises an amorphous-type indium tin oxide film and a poly-type indium tin oxide film below the amorphous-type indium tin oxide film, and the reflective part comprises the poly-type indium tin oxide film and a metal film covering the poly-type indium tin oxide film.

  • Publication number: 20090079351
    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.
