  • Patent number: 7394508
    Abstract: A display device includes a display panel, a driving circuit and a repair line. The display panel has a display region and a peripheral circuit region adjacent to the display region. The peripheral circuit region has a driving circuit bonding region and a plurality of conductive wires extending from the display region into the driving circuit bonding region. The driving circuit is electrically connected to the display region through the driving circuit bonding region and the conductive wires. The repair line is distributed in the peripheral circuit region and the driving circuit, wherein the repair line has a repair portion located between the driving circuit bonding region and the display region. As described above, the repair process of the display device provided by the present invention is simpler so as to save the cost and time of the successive processes.

  • Patent number: 7352429
    Abstract: A display panel includes lower and upper glass substrates. The lower glass substrate includes a pixel array having a plurality of pixel units formed thereon, wherein each pixel unit includes a transparent domain and an opaque domain surrounding the transparent domain, and an upward projection is formed in the opaque domain on the lower glass substrate. The upper glass substrate, mounted on the lower glass substrate, has a spacer formed therebeneath and protruded downwarly therefrom for keeping a cell gap between the upper and lower glass substrates, wherein the spacer is fallen in the opaque domain and has a lateral side in collision with the projection on the lower glass substrate to prevent relative displacement between the lower and upper glass substrates.

  • Publication number: 20080042949
    Abstract: A liquid crystal display includes a gate driver, a source driver, a plurality of scan lines, a plurality of data lines, and a plurality of pixel units arranged in an array. The gate driver is used for generating scan signals. The scan signals include a first voltage level, a second voltage level greater than the first voltage level, and a third voltage level less than the first voltage level. The source driver is used for generating data signals. The plurality of scan lines includes a first scan line, a second scan line, and a third scan line, for delivering the scan signals. The plurality of data lines includes a first data line for delivering the data signals. Each pixel unit includes a first pixel electrode, a first transistor, a second pixel electrode, a second transistor, and a level adjustment unit. The first transistor is used for conducting the data signals from the first data line to the first pixel electrode when the scan signal from the second scan line is at the second voltage level.

  • Publication number: 20070229427
    Abstract: A pixel driving method applied to a flat panel display is provided. In a first time period, an Nth scan line provides a first scan voltage to a pixel row to conduct the corresponding thin film transistors (TFT). Also, an N+1th scan line provides a second scan voltage through the conducted TFTs to the corresponding first switches to conduct the first switches, and then a number of first data voltages of the corresponding data lines are outputted to the corresponding first pixel electrodes. The absolute value of the difference between the first scan voltage and the second scan voltage is not smaller than a threshold voltage of each TFTs.

  • Publication number: 20070222736
    Abstract: A method of driving a liquid crystal display panel is provided. The liquid crystal display panel includes a first scan line, a second scan line, a data line, a first pixel and a second pixel. The first pixel has a first switch, a second switch and a first pixel electrode. The second pixel has a third switch and a second pixel electrode. The driving method includes the following steps. At first, during a first time period, the first scan line and the second scan line are enabled at the same time, a first pixel voltage is inputted to the data line. Then, during a second time period, the first scan line is enabled, the second scan line is disabled, and a second pixel voltage is inputted to the data line. The second time period is shorter than the first time period.
