  • Publication number: 20120146960
    Abstract: A touch pen comprises a penholder, an electrically conducting core, a flexible covering and fabric covering. The electrically conducting core is coupled to the penholder. The electrically conducting core is ensheathed in the flexible covering, while the fabric covering wraps around the flexible covering, wherein either flexible covering or fabric covering has electrical conductivity. In the present invention, the flexible covering and the fabric covering are shaped under the pressure exerted by the electrically conducting core and a touch panel so as to increase the contact area between the touch pen and the touch panel and, meanwhile, the fabric covering is capable of reducing the friction between touch pen and the touch panel, thereby improving the sensitivity and touch effect.

  • Publication number: 20100289792
    Abstract: A method for driving a tri-gate TFT-LCD includes providing a polarity converting common voltage. When polarity of the common voltage is converted, a first gate line is turned on for a source line to charge a first sub-pixel for a first write in duration. When the first gate line is turned off, a second gate line is turned on for the source line to charge a second sub-pixel for a second write in duration. When the second gate line is turned off, a third gate line is turned on for the source line to charge a third sub-pixel for the second write in duration. By adjusting the first write in duration the first sub-pixel can be fully charged, consequently improving the color deviation of the displayed image.

  • Publication number: 20100265002
    Abstract: A driving circuit of LCD includes a common signal generator and a modulation circuit. The modulation circuit can generate a first frequency, a second frequency, and a third frequency. The common signal generator generates a swing common signal according to the first frequency, and modulates the frequency of the common signal in the frequency range between the second frequency and the third frequency.
