Title:
FOLDABLE SCREEN DEVICE, ANGLE MEASUREMENT METHOD AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/007653
Kind Code:
A9
Abstract:
Provided in the present application are a foldable screen device, an angle measurement method and a storage medium. TP wires on two sides of a bending area of a display touch screen in the foldable screen device are connected to each other by means of a switch apparatus, so as to form two electrodes of a capacitive sensor. Different level signals are sent by means of an IC chip to control the switching on or off of the switch apparatus, and when the switch apparatus is switched on, a pulse signal is sent, such that the capacitive sensor, which is formed by means of connecting the TP wires, generates variable charges; and an angle measurement circuit can thus determine a corresponding capacitance value according to the charges, and then measure a folding angle of the display touch screen according to the magnitude of the capacitance value, without the need of a dual A+G apparatus. Therefore, the implementation cost is reduced, and the layout of a mainboard of the foldable screen device is also facilitated.
