Embodiment 1

[0035] Such as image 3 , Figure 4 As shown, this embodiment provides a foldable display device 100 including a foldable module 1 , a sliding device 2 and a display panel 3 . The foldable display device 100 is provided with a non-foldable area 101 and a foldable area 102. In the foldable area 102, the foldable module 1 includes a first substrate 11, a second substrate 12 and 11 and the bending mechanism 4 between the second substrate 12; at least two of the sliding devices 2 are respectively arranged on the first substrate 11 and the second substrate 12; the display panel 3 is installed on the The sliding device 2, the display panel 3 includes a panel folding area 31 and a non-folding area 32, the panel folding area 31 is arranged opposite to the bending mechanism 4; when the display panel 3 is bent, the The display panel 3 can slide relative to the foldable module 1 through the sliding device 2 .

[0036] The display panel 3 is preferably a flexible display panel, which i...

Embodiment 2

[0046] Such as Image 6 As shown, this embodiment provides a foldable display device 100, which includes most of the technical features of Embodiment 1. The difference is that the upper surface of the foldable module 1 is provided with side walls 13 arranged in pairs. The pair of side walls 13 are arranged opposite to each other and their tops are closed together. The side walls 13 and the foldable module 1 are jointly arranged to enclose the guide rail groove 21 .

[0047] Such as Image 6 As shown, in this embodiment, the cross-section of the connecting bump 22 is I-shaped or convex-shaped, and the lower end of the connecting bump 22 is provided with a protruding portion 221, and the protruding portion 221 is clamped in the groove of the guide rail. Within 21.

[0048] After the first substrate 11 and the second substrate 12 are folded, the non-folding area 32 of the display panel 3 is located between the first substrate 11 and the second substrate 12; or the display panel...

Abstract

The invention provides a folding display device. The folding display device comprises a foldable module, sliding devices and a display panel. The foldable module comprises a first substrate, a secondsubstrate and a bending mechanism, wherein the first substrate and the second substrate are arranged oppositely, and the bending mechanism is arranged between the first substrate and the second substrate; the at least two sliding devices are arranged on the first substrate and the second substrate respectively; the display panel is mounted on the sliding devices; the display panel comprises a panel folding area and a non-folding area; the panel folding area is opposite to the bending mechanism; and when being bent, the display panel can slide relative to the foldable module through the slidingdevices. The folding display device solves the technical problem that breakage or wrinkling of the display panel is easily caused due to the fact that the stress of a bending area of the flexible display panel in the folding display device is excessively concentrated, so that the bending radius of the bending area is smaller.

Description

technical field [0001] The invention relates to the display field, in particular to a foldable display device. Background technique [0002] With the development of organic light-emitting display (OLED) technology, especially flexible display technology, foldable flexible display products are getting closer and closer to our life. [0003] Such as figure 1 As shown, it is a schematic plan view of a conventional foldable display device. The foldable display device 90 includes a foldable structure 91 and a display panel 92. The display panel 92 is a flexible display panel, partially or completely fixed on the non-folding structure 91. The folding area 911 and the folding area 912 . Since the different layers of the display panel 92 produce different stresses when they are bent, the smaller the bending radius, the greater the stress, which may easily cause the risk of peeling or breaking between different layers. Therefore, the bending radius of the folding structure 91 canno...
