Abstract: A driving circuit for a touch control panel, that selectively operates in a display mode or a touch mode, includes a display data generating circuit and a touch control circuit. When the driving circuit operates in the display mode, the display data generating circuit transmits display data to multiple data lines of a pixel array of the touch display panel. When the driving circuit operates in the touch mode, the touch control circuit transmits a touch driving signal to the multiple data lines, and performs touch detection by detecting capacitance changes on the multiple data lines.

Abstract: A noise compensating touch panel includes a touch module and a signal compensating module. The touch module includes transmission electrodes and sensing electrodes. The signal compensating module has a first input, a second input and an output. The signal compensating module couples to the touch module. The transmission electrodes receive scanning voltage signals sequentially. When the scanning voltage signals sense the touching by object at crossover points of a first transmission electrode and the sensing electrodes, the sensing electrodes provide sensing signals. The sensing signals include the value of a first parasitical capacitor. The second transmission electrode senses the value of a second parasitical capacitor which the second transmission electrode isn't touched by object when the second transmission electrode receives the scanning voltage signals. Then the second transmission electrode provides compensating signals. Signal compensating module receives the sensing signals and the compensating signals separately.
