| 20100259520 | DISPLAY PANEL, DISPLAY APPARATUS HAVING THE SAME, AND METHOD OF MANUFACTURING THE SAME - A display panel including a first capacitor and a second capacitor is disclosed. The first and second capacitors boost a second driving voltage from a driving chip and apply the boosted second driving voltage to the driving chip. The driving chip receives the boosted second driving voltage and outputs a first driving voltage to drive the display panel. Thus, the display panel does not require any additional capacitor for boosting the second driving voltage, thereby reducing a thickness and a manufacturing cost of the display panel. | 10-14-2010 |

| 20090002336 | DISPLAY DEVICE INCLUDING INTEGRATED TOUCH SENSORS - A display device including a plurality of sensing units, a plurality of first sensing signal lines, a first output unit, a first sensing output line, and a sensing signal processor. The sensing units are arranged in a matrix and generate a detection signal according to user contact. The first sensing signal lines transfer the detection signal of the sensing unit arranged in a first direction. The second sensing signal lines transfer the detection signal of the sensing units arranged in a second direction that is perpendicular to the first direction. The first output unit sequentially outputs the detection signals of the first sensing signal lines. The first sensing output line extends in the second direction for transferring the detection signal of the first output unit. The sensing signal processor determines whether contact is made or not by processing the detection signals of the first sensing signal lines and the second sensing signal lines. The non-display area of the liquid crystal panel assembly can be reduced by sequentially outputting the sensing data signals of the row and column sensing signal lines through the small amount of wiring. Therefore, an IC can be reduced in size. | 01-01-2009 |
