Abstract
(EN)
The present invention relates to the technical field of display, and provides a foldable display apparatus and a control method therefor. The foldable display apparatus comprises a display screen (1); the display screen (1) comprises a first half screen (11) and a second half screen (12), and further comprises a control module and at least one group of angle detection modules (2); each group of angle detection modules (2) are provided on the same surface of the display screen (1), and comprise a transmitter (21) and multiple receivers (22); the transmitter (21) and the first half screen (11) are obliquely provided at a set angle, and the transmitter faces the second half screen (12) and is used for transmitting collimated infrared light; each receiver (22) and the second half screen (12) are obliquely provided at another set angle, and the receiver is in signal connection with the control module and is used for transmitting an electrical signal to the control module when receiving the collimated infrared light; the control module is in signal connection with the display screen (1), and is used for determining a bending angle according to the angle information of the receiver (22) corresponding to the received electrical signal, and controlling the display screen (1) to be switched to the display state of the bending angle. By providing the receivers (22), the present invention detects the bending angle, achieves the change of the display state, and improves user experience.
