20100271327 | DISPLAY PANEL, DISPLAY APPARATUS HAVING THE SAME AND METHOD OF DRIVING THE DISPLAY APPARATUS - In a display panel, a display apparatus having the display panel, and a method of driving the display apparatus, a conductive spacer is interposed between an array substrate and an opposite substrate, and the conductive spacer electrically connects a pixel electrode and a common electrode when a touch event occurs for one or more embodiments. When a common voltage is applied to the pixel electrode by the touch event, an electric potential of a data line is lowered by the common voltage through a turned-on switching device. A signal reader periodically reads out the voltage of the data line and senses the touch event using the read-out voltage to detect a touch position at which the touch event occurs. Thus, the display panel having a touch screen function may be manufactured, and an aperture ratio in the display panel may be prevented from being deteriorated. | 10-28-2010 |
