  • Publication number: 20120293429
    Abstract: A method for detecting touch signals of a touch screen device includes counting a first time slot and a second time slot of an on-off period of a pixel according to a period of a scan signal and a period of a clock signal, and detecting whether the pixel is touched during the second time slot. The first time slot is the time before a noise of the pixel drops to a predetermined value after the pixel is turned on. The second time slot is the time after the noise of the pixel drops to the predetermined value after the pixel is turned on.

  • Publication number: 20110187633
    Abstract: A display including a display panel and a compensation circuit is provided. The display panel includes a plurality of common lines for transmitting a common voltage; a plurality of scan lines; a plurality of data lines disposed substantially perpendicular to the scan lines; a plurality of pixels arranged in an array and each electrically connected to the corresponding data line, scan line, and common line; and a sensing line crossing over at least one first data line among the data lines. A parasitic capacitor is formed between the first data line and the sensing line. The compensation circuit is electrically connected to the sensing line and the common lines. The compensation circuit generates a compensation signal for the common lines according to a coupling signal induced by the parasitic capacitor between the first data line and the sensing line so as to restrain ripple of the common voltage.

  • Publication number: 20080062155
    Abstract: A display device capable of adjusting slew rate includes a display panel, a driving circuit, a storage unit, and a compensating circuit. The display panel includes a plurality of signal lines for signal transmission. The driving circuit is coupled to the display panel for generating driving signals to a signal line of the display panel based on a control signal and a corresponding compensating signal. Data related to each signal line and its corresponding compensating signal is stored in the storage unit. The compensating circuit, coupled to the storage unit and the driving circuit, receives the compensating signal from the storage unit and sends the compensating signal to the driving circuit.

  • Patent number: 7311432
    Abstract: Backlight modules. A backlight module for a flat display device includes a light guide element and a fluorescent lamp assembly. The fluorescent lamp assembly disposed on a first side of the light guide element includes a first fluorescent lamp and a second fluorescent lamp. The first fluorescent lamp comprises a first end, a second end and a first phosphor coating on an inner surface of the first fluorescent lamp, wherein the first phosphor near the first end is thicker than the second end. The second fluorescent lamp comprises a third end adjacent to the second end, a fourth end adjacent to the first end, and a second phosphor coating on an inner surface of the second fluorescent lamp, wherein the second phosphor near the third end is thicker than the fourth end.
