Abstract

The embodiment of the invention provides a curling display device, a method for controlling curling of a flexible display screen and electronic equipment. The curling display device comprises the flexible display screen, two reels, a driving device and a processor. The first reel is arranged on one side of the flexible display screen, and the second reel is arranged on the other side, opposite tothe first reel, of the flexible display screen; the processor is configured to send a control signal for controlling the reels to work to the driving device in response to the curling trigger signal;and the driving device is configured to drive the first reel and / or the second reel to roll towards the direction where the reel on the opposite side is located under the condition that the control signal is received so as to curl the flexible display screen. According to the embodiment of the invention, the reels are additionally arranged, so that the flexible display screen can be curled leftwards or rightwards, damage to the OCA caused by stress generated in a single direction is neutralized in a mode of controlling the two reels to alternately roll through the processor, and the service life of the flexible display screen is prolonged.

Description

technical field [0001] The present disclosure relates to the display field, and in particular to a curling display device, a method for controlling curling of a flexible display screen, and electronic equipment. Background technique [0002] With the development of display technology, the demand for different forms of display devices has been increasing, and bendable or foldable flexible display screens are widely used. The flexible display device includes a flexible display panel, a touch screen, a polarizer, a cover plate, an optical adhesive layer, and the like. [0003] For the flexible display, it can be set on a rollable display device. The curling radius of the display device is usually 5mm-15mm. When rolling, the cover plate is not limited to be close to the shaft end or away from the shaft end. The thickness of the flexible display screen is 50um -250um is not limited. Due to the thickness of the product itself, the flexible display can be curled from 1 circle to 5...
