20080259235 | PIXEL CIRCUIT AND DRIVING METHOD THEREOF IN LIQUID CRYSTAL DISPLAY PANEL AND LIQUID CRYSTAL DISPLAY - A pixel circuit and a driving method thereof in a liquid crystal display (LCD) panel and an LCD are provided. One select line is added to the pixel circuit of the present invention. When the pixel circuit is in a holding state, a select signal is provided to the select line for pulling up the voltage level of the pixel electrode. Therefore, the insertion of the black frames into the images in the LCD panel and the LCD is completed by the present invention during one frame period. | 10-23-2008 |
20080278646 | PIXEL AND DRIVING METHOD THEREOF FOR OPTICALLY COMPENSATED BEND MODE LIQUID CRYSTAL DISPLAY - A pixel including a transistor, a liquid crystal capacitor, a storage capacitor and a coupling capacitor is provided. The first end of the transistor is connected to a data line, the liquid crystal capacitor and the storage capacitor are coupled between the second end of the transistor and a common voltage, and the coupling capacitor is connected between the second end of the transistor and a select line. After a driving voltage is outputted to the liquid crystal capacitor and the storage capacitor by the data line, the select line inputs a pulse signal to the liquid crystal capacitor through the coupling capacitor. The pulse signal is capable of increasing the ability of the electric field for driving the liquid crystal so that the liquid crystal can still display normally in the bend state even though the lowest pixel voltage is lower than the critical voltage. | 11-13-2008 |
20080297461 | DRIVING APPARATUS FOR DISPLAYER AND METHEOD THEREOF - A driving apparatus for a displayer and a method thereof are provided. The driving apparatus includes an image processing unit, a timing controller, and a backlight controller. The image processing unit divides a frame period into an image period and a dark state period. During the dark state period, black (or gray) insertion is performed to an image with a black (or gray) frame through a scan backlight technique. During the image period, the image data is displayed through a dynamic backlight technique. Thereby, the contrast of the displayer is improved and the power consumption thereof is reduced. | 12-04-2008 |

20120120083 | DISPLAY APPARATUS, AND DISPLAY CONTROLLER AND OPERATING METHOD THEREOF - A display apparatus, and a display controller and an operating method thereof are provided. The display controller includes a controller, a buffer, and a compression/decompression unit. The controller receives an original frame from a host. The controller controls a display module to display the original frame provided by the host in a non-still frame mode. The compression/decompression unit is coupled between the buffer and the controller. The controller compresses the original frame to the buffer through the compression/decompression unit. If the controller operates in a still frame mode, the controller decompresses a compressed frame in the buffer to obtain a decompressed frame through the compression/decompression unit, and controls the display module to display the decompressed frame. | 05-17-2012 |
