Title:
BENDING DETECTION DEVICE AND FLEXIBLE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/133277
Kind Code:
A1
Abstract:
A bending detection device (FD), comprising a bending detection module (10) and a bending recognition circuit (12) for detecting the bending state of a flexible display screen body (FB). The bending detection module (10) comprises an elastic sensing element (100), a first conductive assembly (104) and a second conductive assembly (105). The first conductive assembly (104) and the second conductive assembly (105) are disposed opposite to each other and constitute a sensing capacitor (Cx). The elastic sensing element (100) is used for sensing a bending state of the flexible display screen body (FB), and driving the first conductive assembly (104) to generate relative movement relative to the second conductive assembly (105), so as to change a capacitance value of the sensing capacitor (Cx). The bending recognition circuit (12) is electrically connected to the sensing capacitor (Cx), and is used for detecting a change amount of a capacitance value of the sensing capacitor (Cx) and identifying a bending state of the flexible display screen body (FB) according to the change amount of the capacitance value.
