Problems solved by technology

[0005] The foldable flexible display device can fold the screen in half, fold it into a mobile phone, and unfold it into a tablet computer (Pad), but the flexible display screen will be subjected to stress such as tension stress during the folding and bending process of the foldable flexible display device , leading to tensile and compressive deformation, unevenness of the wave (Waving) when the flexible display is folded and bent, and even damage to the internal array substrate circuit and light-emitting devices, resulting in electrical, optical and other adverse phenomena. Therefore, it is necessary to The corresponding folding mechanism is set in the folding flexible display device to compensate the deformation of the flexible display during the folding and bending process, so that the flexible display has no stress during the folding process or the stress is within a safe range

Embodiment Construction

[0023] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0024] see figure 1 , the present invention provides a foldable flexible display device, comprising: a bottom case 1, a sliding mechanism 2, a sliding plate 3, an array of elastic materials 4, a frame 5, and a flexible display 6;

[0025] Wherein, the bottom shell 1 includes: two bottom plates 11 arranged at intervals, and a bending area 12 connecting the two bottom plates 11;

[0026] Each bottom plate 11 is provided with a sliding plate 3, the flexible display screen 6 is fixedly connected with the two sliding plates 3, and a sliding mechanism 2 is arranged between each sliding plate 3 and the bottom plate 11 where it is located. The sliding mechanism 2 Fixed on the bottom plate 11, the sliding plate 3 can slide along the first direction th...

Abstract

The invention provides a folding flexible display device. The device comprises a bottom shell, a sliding mechanism, a sliding plate, an elastic material array, a frame and a flexible display screen. Asliding mechanism is arranged between the sliding plate and the bottom shell. The flexible display screen is arranged on the sliding plate so that when the flexible display screen is bent, the sliding plate can correspondingly slide along with bending of the flexible display screen, meanwhile, an elastic material array is driven to be compressed or stretched, the deformation amount of the flexible display screen in the folding and bending process can be compensated for in real time, the flexible display screen can be naturally recovered to the original length after being unfolded, the phenomenon that the flexible display screen is damaged by force in the folding and unfolding process is avoided, and it is ensured that the flexible display screen is not stressed or the stress of the flexible display screen is within the safety range in the folding process.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a foldable flexible display device. Background technique [0002] With the development of display technology, people have higher and higher requirements for terminal display screens, and flexible display screens have gained people's love and pursuit. Display technologies that can be applied to flexible display screens include liquid crystal display technology, organic light-emitting diode (organic light-emitting diode, OLED) display technology, electrophoretic display technology, electrochromism (electrochromism, EC) display technology, and the like. [0003] Among them, flexible organic light-emitting diode (FOLED) displays have more advantages than other flexible displays, such as self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response, and easy to use. Wide temperature range, simple structure and manufacturing proces...
