Abstract
A method and device for controlling in-plane interference of a liquid crystal touch screen and a display system are provided. By detecting a current image of a display panel of the liquid crystal touch screen in real time, and when the image that causes the in-plane interference of the liquid crystal touch screen is detected, inverting original polarities of data voltages input to at least a portion of data lines of the display panel, so that change directions of coupled voltages of adjacent two of the data lines with respect to a common electrode are opposite to each other, solving problems of in-plane interference for the liquid crystal touch screen.
