Abstract

The embodiment of the application provides a flexible display panel, a display device and a control method thereof. The flexible display panel comprises a display panel body and at least one capacitive sensor. The display panel body comprises a folding area and a non-folding area arranged outside the folding area, and the capacitive sensor for detecting any bending state of the folding area is arranged in the non-display area of the folding area; the capacitive sensor comprises a first electrode arranged in a first conductive layer, a second electrode arranged in a second conductive layer, andan insulating layer arranged between the first electrode and the second electrode. Each of the first electrode and the second electrode comprises a plurality of finger-shaped branches, the finger-shaped branches of the first electrode and the finger-shaped branches of the second electrode are alternately arranged, and the projection areas of the finger-shaped branches in the second electrode andthe projection areas of the finger-shaped branches in the first electrode are at least partially overlapped in any bending state of the folding area. The capacitive sensor is less affected by temperature, no additional temperature compensation circuit is needed, and the manufacturing cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of display devices, and in particular, the present application relates to a flexible display panel, a display device, and a control method for the display device. Background technique [0002] The current flexible display device is a display device formed by manufacturing an organic electroluminescence diode on a flexible base material, and then blocking water and oxygen through a thin film encapsulation layer. Compared with hard-screen display devices, flexible display devices have the characteristics of rollability, wide viewing angle, and portability. Therefore, flexible display devices have broad application prospects and good market potential in various fields related to display devices. [0003] Existing flexible display devices mostly use strain-resistive sensors to detect the bending angle of the screen, by collecting resistance value signals at different bending angles, or using Hall sensors...
