US 2019/0317609 A1 · FLEXIBLE DISPLAY SCREEN, METHOD AND DEVICE FOR DETECTING BENDING OF THE FLEXIBLE DISPLAY SCREEN

Abstract

A flexible display screen includes a first film layer and a second film layer. A first surface of the first film layer is configured with contacts arranged in a matrix. A first surface of the second film layer is configured with chip resistors arranged in a matrix. Resistance values of each chip resistor monotonically vary from a center to an outer edge. The first surface of the first film layer is fitted to the first surface of the second film layer. The contacts are in one-to-one correspondence with the chip resistors, and a detection point is formed by each of the contacts and corresponding chip resistors. Detection points are coupled to a processor configured to detect an intensity of an electrical signal passing through each of the detection points, and determine a bending area of the flexible display screen according to a change of the intensity of the electrical signal.
