  • Publication number: 20110122106
    Abstract: A liquid crystal display device includes a plurality of gate lines, a plurality of data lines, a pixel array, a gate driver, a timing controller, and an optimization circuit. Each pixel unit in the pixel array displays images according to the gate driving signal received from a corresponding gate line and the data driving signal received from a corresponding data line. According to an optimized reference value, the timing controller provides an output enable signal, based on which the gate driver outputs the gate driving signals. The optimization circuit receives a first grayscale data related to display images of a row of pixel units in a first driving period and a second grayscale data related to display images of the row of pixel units in a second driving period, and provides the optimized reference value according the difference between the first and second grayscale data.

  • Publication number: 20110096017
    Abstract: A capacitive touch display panel includes a first substrate, a second substrate, an opaque pattern, a plurality of transparent conductive sensor pads, and a plurality of non-transparent conductive patterns. The first substrate and the second substrate are disposed oppositely. The transparent conductive sensor pads are disposed on the second substrate. The non-transparent conductive patterns are disposed on the second substrate, and the non-transparent conductive patterns and the transparent conductive sensor pads are electrically connected and overlapping. The conductivity of the non-transparent conductive patterns is higher than that of the transparent conductive sensor pads, and the non-transparent conductive patterns are corresponding to the opaque pattern.

  • Publication number: 20110084283
    Abstract: A thin film transistor and a manufacturing method thereof are provided. An insulating pattern layer having at least one protrusion is formed on a substrate. Afterwards, at least one spacer and a plurality of amorphous semiconductor patterns separated from each other are formed on the insulating pattern layer. The spacer is formed at one side of the protrusion and connected between the amorphous semiconductor patterns. Later, the spacer and the amorphous semiconductor patterns are crystallized. Subsequently, the protrusion and the insulating pattern layer below the spacer are removed so that a beam structure having a plurality of corners is formed and suspended over the substrate. Then, a carrier tunneling layer, a carrier trapping layer and a carrier blocking layer are sequentially formed to compliantly wrap the corners of the beam structure. Hereafter, a gate is formed on the substrate to cover the beam structure and wrap the carrier blocking layer.

  • Patent number: 7466324
    Abstract: A method of adjusting the brightness of a display device is provided. The method includes providing a plurality of saturated level-adjust voltages to various level adjustments of the display device when the central brightness is saturated. Then, a computation of the saturated level-adjust voltage of each level adjustment is carried out to obtain a display voltage of each level adjustment. Thereafter, a computation of the saturated level-adjust voltage, a common voltage and the display voltage of each level adjustment is carried out to obtain a feed-through voltage for each level adjustment. After that, a computation of the feed-through voltage and the saturated level-adjust voltage of each level adjustment is carried out to obtain a liquid crystal capacitance value for each level adjustment. Finally, a simulation of the liquid crystal capacitance value of each level adjustment is carried out to obtain an optimized level-adjust voltage for each level adjustment.
