Abstract
This application pertains to display technology, providing a display device and a touch control method. The display device includes a capacitive touchscreen, comprising multiple parallel signal transmission channels and multiple parallel signal reception channels. The signal transmission and reception channels are perpendicular to each other, forming multiple intersecting nodes. At each node, the signal transmission and reception channels are coupled to form a capacitor. A processor is configured to: control a receiving unit to scan the capacitor corresponding to a signal transmission channel, and control the receiving unit to send scan data of the capacitor corresponding to the previous signal transmission channel to the processor; upon acquiring the scan data of each capacitor, locate the touch point based on the scan data. This solution can improve the speed of the display device's touch response to the user based on the touch point, thereby enhancing the user experience.
