IN-CELL TOUCH SCREEN AND A METHOD OF DRIVING THE SAME |
| 摘要 |
The present invention is directed to a method of driving an in-cell touch screen. A common voltage (VCOM) layer of the in-cell touch screen is divided into transmit (TX) electrodes and receive (RX) electrodes, the TX electrodes forming TX electrode lines in a first direction and the RX electrodes forming RX electrode lines in a second direction. The TX electrode lines are arranged into a plurality of groups. The groups of TX electrode lines are concurrently scanned in touch sensing mode. |
