Sliding roll display device

Abstract

The embodiment of the invention discloses a sliding roll display device. The sliding roll display device comprises a sliding roll screen, a sliding roll driving mechanism, a light detector and a control module; the sliding roll screen comprises a flexible display screen and a supporting sheet which are arranged in a stacked mode, wherein the supporting sheet is located on the side, away from the light emitting side, of the flexible display screen; a plurality of hollow patterns are arranged on the supporting sheet; the light detector is used for collecting the light intensity change of the area where a hollowed-out pattern is located on the supporting sheet; the control module is used for determining the actual extension amount of a sliding roll screen according to the light intensity change of the area where the hollowed-out pattern is located collected by the light detector, and comparing the actual extension amount with a theoretical extension amount to calculate the deformation amount of the sliding roll screen; and the control module is also used for controlling the sliding roll driving mechanism to compensate the roll shrinkage amount of the sliding roll screen according to the deformation amount of the sliding roll screen. According to the sliding roll display device of the embodiment of the invention, the problem that a flexible screen is loosened due to the fact that an existing sliding roll screen is easy to wrinkle due to multiple times of sliding roll is solved; tension can be provided for the extending sliding roll screen, so that the sliding roll screen is in a tightened state, and smooth display of the extending sliding roll screen is ensured.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a scroll display device. Background technique [0002] Nowadays, flexible display panels have gradually entered the field of vision of consumers, and the rollability of the screen has greatly expanded the application in the display field. Compared with traditional screens, flexible screens have obvious advantages. Not only are they thinner and thinner in size, but they also consume less power than traditional devices, which helps to improve the battery life of devices. At the same time, based on the characteristics of bendability and flexibility, its durability is also much higher than that of traditional screens. [0003] When flexible screens are used in display devices, folding screens or sliding screens can generally be used. Among them, folding screens need to be folded by connecting components, such as connecting shafts or hinge structures at th...

[0004] However, the flexible screen in the slide-and-roll display is easily deformed by pulling due to multiple stretching and rolling processes. Therefore, the flexible screen is prone to wrinkle or wrinkle due to local deformation during the display process or after rolling. , resulting in uneven display and loose flexible screen
