Embodiment Construction

[0026] In practical applications, in order to prevent the two sides of the flexible display from springing back after being folded, the two sides are usually connected mechanically. For example, a buckle is set on the frame of the flexible display so that the folded sides can pass through The buckle at the frame position is mechanically connected. However, the mechanical connection method increases the frame width and overall weight of the flexible display screen, and reduces the aesthetics of the flexible display screen.

[0027] In order to achieve the purpose of the present application, an embodiment of the present application provides a flexible display screen, in which a bending area, a first display area, a second display area, a chip and a power supply are provided, and the chip is configured to monitor bending The radius of curvature of the folding area, and when it is determined that the radius of curvature is less than or equal to the preset threshold, a power supply in...

Abstract

The invention discloses a flexible display screen and a display device. The flexible display screen comprises a bending area, a first display area, a second display area, a chip and a power source. The chip is used for monitoring a curvature radius of the bending area and sending power supply instructions to the power source when the curvature radius is smaller than or equal to a threshold. A first metal coil and a second metal coil are arranged in the first display area and the second display area respectively. The power source is used for providing currents in opposite directions for the first metal coil and the second metal coil to enable the first metal coil and the second metal coil to generate electromagnetic force enabling mutual attraction of the first display area and the second area when the power supply instructions are received. The flexible display screen and the display device have the advantage that resilience of two sides of the folded flexible display screen can be effectively avoided.

Description

Technical field [0001] This application relates to the field of flexible display technology, and in particular to a flexible display screen and a display device. Background technique [0002] Flexible display has the characteristics of light weight, not easy to break, bendable, etc., and has become the future development direction of the display industry. [0003] At present, in order to realize the portability and large-screen display of the flexible display screen, a foldable flexible display screen has appeared. The foldable flexible display screen can generally be reduced in size after being folded, and a large screen display can be realized after unfolding. However, the foldable flexible display screen in the prior art may rebound on both sides after being folded. figure 1 It is a schematic diagram of the rebound on both sides of the flexible display screen after folding in the prior art. Summary of the invention [0004] The embodiments of the present application provide a f...
