Embodiment Construction

[0055] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0056] The bonding method of the foldable display panel according to the present invention is to use the bonding device of the foldable display panel according to the present invention to bond the overlapping optical film layers in a bent state.

[0057] Specifically, as Figure 4A with Figure 4B As shown, the bonding device of the foldable display panel according to the present invention includes a first jig 100 and a second jig 200, the first jig 100 has a convex outer surface 110, and the second jig 200 Having a concave inner surface 210 , the outer surface 110 conforms to the inner surface 210 in shape.

[0058] The pasting device also includes a moving unit 300 . exist Figure 4A with Figure 4B In the illustrated embodiment, the second jig 200 can be moved by the moving unit 300 . Specifically, the fixing part 310 on the moving unit 300 is connected...

Abstract

The invention discloses a foldable display panel, and a laminating method and a laminating device thereof. The laminating device comprises: a first jig having a convex external surface and a second jig having a concave internal surface; an aid film, wherein a plurality of optical films can be pasted on the upper surface of the aid film; and fixing units used for detachably supporting and fixing the aid film. The fixing units can move relative to the first tool to make the lower surface of the aid film closely attached to the external surface of the first jig; and the first jig can move relative to the second jig to make the external surface of the first jig and the internal surface of the second jig aligned and mutually abutted against each other in order to laminate the plurality of optical films together. The plurality of optical films which are arranged in an overlapping manner are laminated in an overlapping manner in a bent state in the invention in order to reduce the stress accumulated by every optical film or avoid the accumulated stress.

Description

technical field [0001] The present invention relates to the field of flexible displays, in particular to a foldable display panel, a bonding method and a bonding device thereof. Background technique [0002] The existing foldable active matrix organic light-emitting diode panel (AMOLED) is usually stacked with a flexible cover (Cover film), touch screen panel (touch screen panel, TSP), circular polarizer (circular polarizer, CPOL), Display device (Panel), back film (Bottom Film) and other optical film layers, these optical film layers are laminated in a flat state. However, when the display panel is folded and unfolded many times, the stress distribution is caused by the difference in elastic modulus of the material forming each optical film layer and the difference in performance of the components included in each optical film layer. Not uniform, so each end of the foldable display panel strains to different degrees due to the accumulation of stress. When the display pane...
