  • Publication number: 20120081343
    Abstract: A display array organization used in a display panel is provided. The display array includes a data line, a first scan line, a second scan line, a first pixel electrode, a second pixel electrode, a front-end switch and an intermediary switch. The first pixel electrode is connected to the data line with the front-end switch, and the second pixel electrode is connected to the first pixel electrode with the intermediary switch. The operation of the front-end switch and intermediary switch are controlled by the first and second scan line respectively. When only the front-end switch is activated, the first pixel electrode can receive the data signal from the data line. When both the front-end and intermediary switches are activated, the second pixel electrode can receive a data signal from the data line.

  • Patent number: 6466281
    Abstract: An active cell for a thin-film transistor liquid crystal display, with integrated black matrix/color filter, includes a switching device, a data line, a scanning line, a planarization layer, a light shielding layer, a dielectric layer, a first electrode layer, a liquid crystal layer, a second electrode layer, and a counter plate. The switching device is formed on the substrate, wherein the data line supplies data signals to the switching device and the scanning line supplies controlling signals to the switching device. The planarization layer is formed on the switching device and has a contact opening which is extended down to a driven end of the switching device. The light shielding layer is on a portion of the planarization layer and the dielectric layer is on the light shielding layer and a top planar region of the planarization layer.

  • Publication number: 20010050745
    Abstract: An in-plane switching liquid crystal displaying device comprises a common electrode main line; a plurality of common electrodes connecting to the common electrode main line; a pixel electrode main line; a plurality of pixel electrodes connecting to the pixel electrode main line and overlapping the common electrodes; and a isolation layer disposed between the common electrodes and the pixel electrodes. The storage capacitance of the pixel device can be increased by using the additional capacitance generated from the overlaps of the pixel electrodes and the common electrodes. Therefore, the area required by the storage capacitor could be reduced to increase the aperture ratio. In addition, the present invention can be carried out with almost no increase in cost.

  • Patent number: 6163355
    Abstract: A process for manufacturing an in-plane switching array of a liquid crystal display. A thin-film transistor including a drain, a source and a data line as well as first and second electrodes are fabricated on a cleaned glass substrate. The source, the drain and the data line comprise the same conductive layer as the second electrode. The conductive layer includes a top aluminum layer and a bottom Cr layer. A photo-resist layer is coated and patterned to expose only the area of the second electrode. The top aluminum layer of the second electrode is then etched away to decrease the thickness. Because of the thinner second electrode, the rubbing process can be uniformly completed. The light leak near the edge of the electrode is reduced without increasing the resistance of the data line.
