  • Publication number: 20120013573
    Abstract: A pressure detectable touch device includes a first substrate, a conductive layer formed on the first substrate, a second substrate, a first electrode pattern, a second electrode pattern, and a microprocessor. When a user touches a touch operation surface of the touch device in such an extent that the conductive layer and the first electrode pattern are not put into physical contact with each other, the touch device is set in a capacitive touch position detection mode. When the user forcibly depresses the touch operation surface of the touch device or carries out a hand writing input operation on the touch operation surface of the touch device, the conductive layer is caused to physically engage the first electrode pattern, setting the touch device in a resistive touch position detection mode.

  • Publication number: 20080143663
    Abstract: A liquid crystal display panel and an active array substrate thereof are disclosed. The projected area of the pixel electrodes in each display sub-region is reduced gradually to decrease the parasitic capacitance, the liquid crystal capacitance, and/or the storage capacitance. Therefore, the total capacitance value of each pixel is decreased gradually also. The feed through voltage ?Vp is compensated by the capacitance to make the feed through voltage ?Vp around the liquid crystal display panel approach unity to improve the display quality.
