LIQUID CRYSTAL DISPLAY HAVING TOUCH INPUT SENSING AND TOUCH SENSING METHOD THEREOF |
摘要 |
A liquid crystal display having touch input sensing includes a display panel and sensing units integrated in the display panel. The display panel has scan lines for delivering scan signals and readout lines for delivering readout signals. The sensing unit resets a sensing voltage according to a low-level voltage of the scan signal. Further, the sensing unit pulls up the sensing voltage according to a high-level voltage of the scan signal and an increase of the sensing voltage is under the control of a touch event. The readout signal is generated by the sensing unit based on the sensing voltage and the high-level voltage of the scan signal.
