Abstract

The invention discloses a three-dimensional force recognition sensor, its driving method and a display device. A first conductive layer and a second conductive layer are respectively arranged on both sides of a pressure-sensitive conductive layer, wherein the first conductive layer includes multiple A group of first electrode groups, and each first electrode group includes two first electrodes extending along the first direction, arranged side by side and insulated; the second conductive layer includes multiple groups of second electrode groups arranged side by side, and each second electrode group It includes two second electrodes extending along the second direction, arranged side by side and insulated. The resistance of the pressure-sensitive conductive layer changes when there is pressure, so the direction of the horizontal pressure can be judged by using the resistance change between the same electrode and a group of electrodes located on another conductive layer. And by using the capacitance between the first electrode group and the second electrode group will change when there is pressure, the magnitude of the vertical pressure can be judged. In this way, the identification and judgment of three-dimensional force can be realized.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a three-dimensional force recognition sensor, its driving method and a display device. Background technique [0002] With the continuous development of touch technology, the application of pressure touch detection greatly improves the user experience. At present, pressure recognition is mainly used to recognize the pressure pointing to the bottom of the screen, and there is a lack of applications for recognizing horizontal force. Among them, the application of horizontal direction force recognition is, for example, mobile games. During the game, moving up, down, left, and right is often operated by sliding the screen. By identifying the force in the horizontal direction, the movement trend of the finger in the horizontal direction can be determined, so as to improve user experience. [0003] Therefore, how to provide a sensor capable of recognizing three-dimensional force is a ...
