Title: TOUCH CONTROL FORCE DETECTION METHOD, TOUCH CONTROL FORCE DETECTION DEVICE, TOUCH CONTROL PANEL AND DISPLAY DEVICE
Abstract:
Provided are a touch control force detection method, a touch control force detection device, a touch control panel and a display device. The touch control force detection method comprises: step S1, obtaining the number of touch control points N of a panel to be detected, where N is an integer greater than or equal to 1; step S2, randomly selecting M test positions on the panel to be detected, where M is an integer greater than or equal to N, and obtaining the capacitance variation amount of each of the test positions, wherein the capacitance variation amount is a variation amount in the capacitance between a sensing electrode and a reference electrode of the panel to be detected at a test position when the panel to be detected is touched; step S3, obtaining a panel deformation amount of each of the test positions according to the capacitance variation amount at each of the test positions; and step S4, calculating a touch control force at the touch control point according to a correlation between the panel deformation amount and the touch control force. The touch control force detection method can detect the touch control force of a single finger or a plurality of fingers.
