LIQUID CRYSTAL DISPLAY WITH SENSOR FUNCTION AND ITS METHOD OF DETECTING THE TOUCH Russian patent published in 2018 - IPC G09G3/36 G06F3/41 G02F1/1333 

FIELD: images forming devices.

SUBSTANCE: invention relates to liquid crystal displays with a sensory function and a touch detection method implemented therein. Liquid crystal display with a touch function contains a display module and a sensor module, and they use a common electrode whose voltage is stable. Display module comprises a gate drive signal generator and a data transmitter. Display module sequentially performs a variety of operations for generating the gate control signals and generating grayscale in each frame. Sensor module performs touch detection operations, while the display module performs the current operation to generate shutter control signals and generate grayscale. In this case, the sensor module performs touch detection operations, and the data transmitter generates gray grayscale signals.

EFFECT: technical result consists in reducing the mutual influence of the display signals and sensory signals in order to improve the quality of the display and the effectiveness of the sensory function.
