  • Publication number: 20100134427
    Abstract: A display panel with multi-touch function includes a display area and a non-display area. The display area includes a data line, a gate line, a first sensing line, a second sensing line, and a sensing unit. The sensing unit electrically connects the first and second sensing lines according to a touch signal or electrically isolates the first sensing line from the second sensing line. The non-display area includes a gate driver, a first switch and a second switch. The first switch provides a path for charging the second sensing line according to a scan signal, and the second switch provides a path for discharging the second sensing line according to a reset signal.

  • Publication number: 20100039405
    Abstract: A projective capacitive touch apparatus and a method for identifying multi-touched positions are provided. The multi-touched positions are touched on a projective capacitive touch panel. The method comprises the following steps: generating a first set of reference values according to the first touch position; generating a plurality of second sets of reference values according to a second touch position, and filtering out at least one ghost second set of reference values from the second sets of reference values. Furthermore, the plurality of second sets of reference values comprise a real second set of reference value and at least one ghost second set of reference values, while the ghost second set of reference values comprises parts of the first set of reference values.

  • Publication number: 20100001965
    Abstract: An electroluminescent display touch panel includes a base substrate and an encapsulating substrate. The base substrate includes a pixel switching device, a readout device, an electroluminescent device, and a sensing pad. The pixel switching device and the electroluminescent device are disposed in a display region. The readout device and the sensing pad are disposed in a non-display region. The encapsulating substrate includes a first spacer, a sensing spacer, and a conductive layer. The first spacer is disposed on the surface of the encapsulating substrate facing the base substrate, maintaining a cell gap between the base substrate and the encapsulating substrate. The sensing spacer is disposed on the surface of the encapsulating substrate facing the base substrate and corresponding to the sensing pad. The conductive layer is formed on the surface of the sensing spacer facing the sensing pad.

  • Publication number: 20090009461
    Abstract: An over-driving device is provided. In a first frame, a compression circuit compresses a first image signal to generate a first compression image signal, and a buffer temporarily stores the first compression image signal. In a following second frame, the compression circuit compresses a second image signal to generate a second compression image signal, and the buffer outputs the first compression image signal to serve as a first buffer image signal. A comparison circuit compares the second compression image signal and the first buffer image signal and generates an enable signal according comparison result. A decompression circuit decompresses the first buffer image signal to generate a previous image signal. An over-driving unit receives the second image signal to serve to a current image signal and receives the previous image signal and the enable signal. The over-driving unit over drives the display device or not according to the enable signal.
