  • Publication number: 20090103026
    Abstract: The present invention discloses a transflective liquid crystal display panel, which includes a first substrate, a second substrate and a liquid crystal layer sandwiched between the first and second substrates, so as to constitute a plurality of pixels each divided into a transmission region and a reflective region. Within the reflective region, a first common electrode layer formed on the first substrate corresponds to both of a second common electrode layer and a pixel electrode layer formed on the second substrate, wherein the pixel electrode layer is exposed from a plurality of apertures formed on the second common electrode layer. This varies distribution of the electric lines so as to control tilts of the liquid crystals in the reflective region. By the tilts, a total retardation change value achieved in the reflective region can gradually reach consistent with a total retardation change value achieved in the transmission region.

  • Publication number: 20090084613
    Abstract: A capacitive touch panel and a display device using the capacitive touch panel are provided. The capacitive touch panel includes a plurality of first direction electrode strings and second direction electrode strings. Each first direction electrode string has a plurality of first electrodes while each second direction electrode has a plurality of second electrodes. In order to reduce the lateral capacitance between adjacent electrodes, width of the first electrode is reduced from the middle to two sides of the electrode along a second direction. In addition, the first electrode has a perimeter surrounding itself. Each quarter of the perimeter of the first electrode facing the adjacent second electrode has a first slope change rate and a different second slope change rate.

  • Publication number: 20090085885
    Abstract: A touch panel and a manufacturing method thereof are provided. The touch panel has a double-layered sensing pad structure or a single-layered sensing pad structure. In the double-layered sensing pad structure, the sensing pads in each layer have corresponding dummy sensing pads in the other layer for compensating the difference of transmittance. In the single-layered sensing pad structure, the sensing pads are coplanar so that the problem of color shift can be overcome and the visual effect of the touch panel can be improved.
