Embodiment 1

[0043] like Figure 1a and Figure 1b The shown flexible display embodiment 1 of the embodiment of the present invention includes a bendable display body, and the display body includes a base substrate 1 made of a flexible material, and the base substrate 1 has two grooves 2 thereon. like Figure 1a As shown, the two grooves 2 are respectively located at the two ends of the display body in the non-bending direction (when the size of the flexible display is small, the groove 2 can only be provided at one end) and correspond to the non-display area of ​​the flexible display (that is, area outside the display area). In Embodiment 1, the base substrate 1 is, for example, a rectangle, and the bending direction of the flexible display refers to the direction along the long side of the rectangle, while the flexible display cannot be bent in the direction corresponding to the short side of the rectangle. A supporting body 3 is respectively arranged in the two grooves 2 . In order fo...

Embodiment 2

[0047] Embodiment 2 of the present invention provides a support body for a flexible display, such as figure 2 As shown, the support body is made of manganese steel and other spring materials used to make springs, and the whole is roughly in the shape of a strip-shaped sheet. The edge portion 91 of the support body in the width direction is configured to have a warp in the width direction. Curved and has a tendency to open in the length direction, the middle part 92 of the support body in the width direction is configured to have a tendency to crimp in the length direction (the curvature of the crimp can be set), so that it can be stretched in the length direction. Open can also be crimped, and can be warped in the width direction as well as unfolded, with the warping in the width direction and the crimping in the length direction being towards different sides of the sheet. Because the curvature of the crimping of the support body 3 in the length direction can be set, the supp...

Embodiment 3

[0051] like image 3 The flexible display embodiment 3 shown in the embodiment of the present invention is mainly different from the above-mentioned embodiment 1 in that five parallel grooves 2 are distributed on the base substrate 1, and the grooves 2 are arranged in parallel along the bending direction of the flexible substrate. The support body 3 is arranged in the groove 2, and there are multiple support bodies side by side. By arranging 5 support bodies, the force can be more uniform, and the recovery and ability of the display body to maintain opening and curling can be enhanced.

Abstract

The invention relates to a flexible display and a flexible display device. The flexible display comprises a flexible display body, and the flexible display body is provided with supporting bodies which can support the display body no matter the display body is in an unfolding state or a folding state. According to the flexible display and the flexible display device, a display substrate is prevented from being bent excessively by using the strength of the substrate, smoothness of the display substrate can be maintained automatically when the flexible display device is unfolded, and therefore the situation that the display substrate is damaged due to the fact that the display substrate is bent excessively can be avoided. The flexible display device can be put on the wrist conveniently.

Description

technical field [0001] The invention relates to the technical field of flexible display, in particular to a flexible display and a flexible display device. Background technique [0002] With the continuous development of flat panel display (FPD), it is necessary to realize the curved display of a large panel that pursues a realistic sense of presence, and the flexibility of a roll-up mobile terminal that pursues portability and convenience. Substrates with both flexibility and impact resistance have become indispensable. Materials such as glass substrates and polyimide resins are widely used as substrates for FPDs. However, flexible substrates are prone to breakage and damage due to excessive bending or cause internal devices to fall off, which affects performance life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flexible display for the above-mentioned deficiencies in the prior art, which can prevent exc...
