Abstract

The invention provides a flexible touch panel. The flexible touch panel comprises a driving electrode layer, an insulating layer, an induction electrode layer, an IC detection circuit and a controller, The driving electrode layer, the insulating layer and the induction electrode layer form a plurality of latticed induction capacitor units; The induction capacitor units are distributed in an arraymode in the horizontal direction and the vertical direction. A lead of the induction capacitor unit is connected with the IC detection circuit; The capacitance detection unit is used for detecting a capacitance detection signal of the induction capacitance unit and sending the capacitance detection signal to the controller; The controller is used for calculating the capacitance change quantity ofthe induction capacitance units according to the capacitance detection signal and determining the bending position of the flexible touch panel according to the capacitance change quantity of the induction capacitance units in any two adjacent rows or any two adjacent columns; According to the flexible touch panel, no extra deformation sensing element needs to be added, the bending position detection method is simple, the bending effect is not affected, and meanwhile the manufacturing cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of flexible display devices, and in particular to a flexible touch panel, a display device and a bending region detection method thereof. Background technique [0002] With the continuous development of the flexible touch panel industry, flexible panels with touch display, bendable, flexible deformation and other functions are widely used in people's daily life and work. [0003] The existing technical solutions use deformation sensing elements attached to the flexible touch panel to detect the touch and bending position and degree information of the flexible panel, and then feed back to the touch panel. Make corresponding adjustments. [0004] To sum up, the deformation sensing element increases the overall thickness of the flexible touch panel, the detection method is complicated, and the bending effect is affected at the same time. Contents of the invention [0005] The invention provides a fl...
