20150205429 | TOUCH DRIVER CIRCUIT, IN-CELL OPTICAL TOUCH PANEL AND DISPLAY DEVICE - The invention discloses a touch driver circuit, an in-cell optical touch panel and a display device. The touch driver circuit comprises a photosensor module, a data writing module, a driver module, and a control module. The data writing module transmits a scan signal at a scan signal terminal to the driver module under the control of the scan signal terminal. When the scan signal drives the driver module to turn on, the driver module outputs a touch sensing signal to the control module; the touch sensing signal decreases with the increase of an intensity of light irradiated on the photosensor module. Under the control of the control signal, the control module outputs the touch sensing signal output by the driver module to the touch signal sensing terminal, thereby realizing the touch sensing function. Compared with a conventional in-cell optical touch panel, the driver module transmits the touch sensing signal to the touch signal sensing terminal under the control of the control module, and in the case where touch signal sensing terminals of driver circuits of different stages are connected to the same touch signal sensing line, the cross-talk between the signals output at the touch signal sensing terminal of the driver circuits of different stages can be avoided. | 07-23-2015 |
