Embodiment 1

[0086] Such as Figure 5 to Figure 8 As shown, the cross section of the second chute 121 of the second support member 120 of the support device 100 is an inverted “T” shape; correspondingly, the cross section of the first slider 111 of the first support member 110 is the same Matching inverted "T" glyph.

[0087] In other embodiments, the cross-sectional shapes of the chute and the slider of the first support member 110 and the second support member 120 may also be interchanged. For example, the cross-section of the first chute provided on the first support member 110 of the support device 100 is “T”-shaped; "T" shape.

Embodiment 2

[0089] Such as Figure 9 to Figure 11 As shown, the cross-section of the second chute 121 provided by the second support member 120 of the support device 100 is dovetail-shaped; correspondingly, the cross-section of the first slider provided by the first support member 110 is matched Swallowtail.

[0090] In other embodiments, the cross-sectional shapes of the chute and the slider of the first support member 110 and the second support member 120 may also be interchanged. I won't repeat them here.

[0091] As an optional implementation, such as Figure 6 and Figure 9 As shown, the gap between the first sliding slot and the second sliding block is 0.1 mm˜0.2 mm; or, the gap between the first sliding block 111 and the second sliding slot 121 is 0.1 mm˜0.2 mm.

[0092] In this embodiment, in order to avoid the self-locking phenomenon of the relative sliding between the first support member 110 and the second support member 120, the gap between the first sliding groove and the...

Embodiment 3

[0096] Such as Figure 12 As shown, the first supporting member 110 of the supporting device 100 is provided with a first sliding block 111, and the second supporting member 120 is provided with a second sliding groove 121, and each edge of the first sliding block 111 and the second sliding groove 121 is set to be inverted. horn. Compared with the embodiment in which the edges of the first slider 111 and the second chute 121 are at right angles, when the first slider 111 and the second chute 121 slide relative to each other in the first direction, the first slider 111 and the second chute 121 can avoid the first The right-angled edges of the slider 111 and the second chute 121 are locked and locked to each other, and the flexible display screen 200 is bent and / or flattened when the first slider 111 and the second chute 121 slide relative to each other in the first direction. The displacement difference of the chain 300 relative to the flexible display 200 is compensated. Sin...

Abstract

The invention discloses a display device, and the device comprises a flexible display screen which comprises a bending region and a non-bending region; the supporting device comprises a first supporting piece and a second supporting piece, the first supporting piece is connected with the non-display surface of the bending area of the flexible display screen, and the side, away from the flexible display screen, of the first supporting piece is in sliding connection with the second supporting piece; the chain is connected with the side, away from the first supporting piece, of the second supporting piece, and the length direction of the chain is perpendicular to the bending shaft of the bending area; the rotating shaft is connected with the chain, the rotating shaft is parallel to the bending shaft, and the chain can be unfolded or bent around the rotating shaft; wherein the sliding direction of the first supporting piece relative to the second supporting piece is the same as the displacement direction of the flexible display screen relative to the chain when the flexible display screen is bent and / or flattened. According to the display device, the displacement of the flexible display screen relative to the chain in the bending and / or flattening process is compensated by utilizing the fact that the first supporting piece can slide in the first direction relative to the second supporting piece, and creases or arches are avoided.

Description

technical field [0001] The present application belongs to the technical field of flexible display, and in particular relates to a display device. Background technique [0002] Flexible displays are often designed to be foldable to meet different usage needs. The flexible display generally adopts the solution of the outer folding shaft to realize the foldable function of the flexible display, such as image 3 As shown, the flexible display screen includes a bending area and a non-bending area, and a chain and a rotating shaft are arranged in the bending area, and the chain is bonded and fixed on the non-display surface of the bending area through an adhesive material, and the chain is realized through the adhesive material. The function of fixing and supporting the bending area; the chain is bent around the rotating shaft to realize the bending function of the bending area. However, due to the small fixed area between the chain and the bending area, it cannot provide suffici...
