| 20080198122 | Display device and method of driving the same - A display device includes a gate driving part, a data driving part, a display panel and a kickback voltage compensating part. The gate driving part outputs a gate signal, and the data driving part outputs a data signal. The display panel displays an image in response to the gate signal and the data signal. A pixel voltage of the display panel is reduced by a kickback voltage varied based on a gray scale and induced when the gate signal falls. The kickback voltage compensating part compensates an image control signal externally provided to the kickback voltage compensating part for the kickback voltage to output a data control signal to the data driving part. | 08-21-2008 |
| 20080231779 | Display substrate and display apparatus having the same - A display substrate includes a pixel layer, a color filter layer and a pixel electrode. The pixel layer includes a first storage electrode, a second storage electrode and a third storage electrode respectively associated with a red pixel, a green pixel and a blue pixel. At least one of the first, second and third storage electrodes has a different area from a remainder of the storage electrodes. The color filter layer includes a red color filter, a green color filter and a blue color filter formed on the pixel layer. The red, green and blue color filters respectively correspond to the red pixel, the green pixel and the blue pixel. Pixel electrodes are formed on the color filter layer. The pixel electrodes correspond to the red, green and blue pixels. | 09-25-2008 |
| 20090096730 | DISPLAY SUBSTRATE, DISPLAY DEVICE HAVING THE SAME AND METHOD OF DRIVING THE SAME - A display substrate includes first and second storage electrodes, a pixel electrode and a direction control electrode. A slit is formed through the pixel electrode. The direction control electrode is positioned in a region aligned with the slit, and a level of a voltage applied to the direction control electrode is changed. The level of the voltage applied to the direction control electrode may be periodically changed. The voltage applied to the direction control electrode may be changed after substantially the same voltage is applied to the pixel electrode and the direction control electrode. A voltage difference between a reference voltage and the direction control voltage may be greater than a voltage difference between the reference voltage and the pixel voltage. The reference voltage may be a common voltage. | 04-16-2009 |
| 20090096950 | THIN FILM TRANSISTOR PANEL - A thin film transistor panel is provided. The thin film transistor panel includes: a substrate; gate lines formed on the substrate; data lines insulated from the gate lines and intersecting the gate lines; thin film transistors which are connected to the gate lines and the data lines and have drain electrodes; capacitive coupling electrodes connected to the drain electrodes; and pixel electrodes which are formed in the pixels surrounded by the gate lines and the data lines and include first pixel electrodes connected to the drain electrodes and second pixel electrodes which are separated from the first pixel electrodes and overlap with the capacitive coupling electrodes, wherein the first and second pixel electrodes of different pixel electrodes have a left-right symmetrical structure. | 04-16-2009 |
