Embodiment Construction

[0064] The present application will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0065] It should be noted that the orientation words such as "up", "down", "left", and "right" described in the embodiments of the present application are described from the angles shown in the drawings, and should not be interpreted as limiting the implementation of the present application. Example limitations. Furthermore, in this context, it also needs to be understood that when it is mentioned that an element is formed "on" or "under" another element, it can not only be directly formed "on" or "under" another element, but also be formed "on" or "under" another element. An element may be formed "on" or "under" another element indirectly through intervening elements.

[0066] Please refer to Figure 3a , Figure 3a A schematic diagram showing an embodiment of a display device in an unfolded state.

Abstract

The invention relates to a folding display screen and a display device. The folding display screen has a folded state and an unfolded state and comprises a first portion, a second portion, a flexible portion and bend guide portions. Under the folded state, the first portion is opposite to the second portion; the first portion is connected with the second portion through the flexible portion, the folding display screen is folded at the flexible portion, and the flexible portion comprises a first surface and a second surface in opposite arrangement along the thickness direction of the folding display screen. Each bend guide portion comprises an elastic layer and an additional layer, wherein the elastic layer and the additional layer are in laminated arrangement, the elastic layer is adhered to the first surface, and the additional layer is provided with gaps which extend towards the elastic layer from the surface, away from the elastic layer, of the additional layer. Under the folded state, the surface, away from each elastic layer, of the corresponding additional layer is open at the gap positions. By the scheme, the flexible portion can be guided to bend towards a set direction, damages of the folding display screen are reduced, and the service life of the folding display screen is prolonged.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a foldable display screen and a display device. Background technique [0002] The foldable display can be unfolded when in use to realize a large-area display, and can be folded when not in use for easy storage and portability. Currently, foldable display screens have been applied to various electronic devices, such as mobile phones, notebook computers, digital media players, and so on. [0003] However, when the display screen is folded, since the bending direction of the display screen is uncertain, the flexible part of the display screen may bend in opposite directions. Such as figure 1 and figure 2 as shown, figure 1 A schematic diagram showing a bending in which the flexible part of the display screen is concave inward, figure 2 A schematic diagram showing the bending of the flexible portion of the display screen protruding outward. [0004] figure 1 The ...
