In a flexible display panel and a flexible display device provided by the present application, a bending end of a support layer is configured inwardly to be shorter than a flexible display module to reduce a bending angle of the support layer. In this way, bending stress on the support layer can be reduced, thereby increasing attachment quality of the support layer and improving attachment reliability.

The present invention provides a backplate and a display device. The backplate is adapted for a display device, the display device includes a bending region, and the backplate includes a bonding region configured to bond to the bending region of the display device. The bonding region includes at least one cutout. When the bending region and the bonding region are bent, squeezing stress is applied to the bending region, the at least one cutout contracts inwardly to reduce the squeezing stress applied to the bending region.

A foldable display screen and an assembling method thereof, and a display apparatus are provided. The foldable display screen includes: a display panel; a touch sensing panel, located on a side of the display panel; a first optical adhesive layer, located on a side of the touch sensing panel away from the display panel; and a second optical adhesive layer, located between the display panel and the touch sensing panel; a thickness of the first optical adhesive layer and a thickness of the second optical adhesive layer are both 20 μm to 200 μm; and at a working temperature, an elastic modulus of the first optical adhesive layer and an elastic modulus of the second optical adhesive layer are both less than 1 Mpa.

A foldable display screen and a manufacturing method thereof, and a display apparatus are provided. The foldable display screen includes a display panel and an optically clear adhesive (OCA) layer. The display panel includes a bending region and a non-bending region; and the bending region is configured to be bent along an axis extending in a first direction, the non-bending region is on at least one side of the bending region in a second direction. The OCA layer includes a first portion and a second portion, the first portion is in the bending region, an edge of the first portion in the first direction overlaps with an edge of the bending region in the first direction, the second portion is located in the non-bending region, and a spacing is formed between the second portion and an edge of the non-bending region in the first direction.

A rollable display device having a normal display status and an expanded display status is disclosed. The rollable display device includes a display layer and an optical layer. The display layer has a greater display area when the rollable display device is in the expanded display status than in the normal display status. The optical layer is attached to the display layer through an adhesive, and the optical layer includes a base layer and a functional layer disposed between the base layer and the adhesive. The functional layer is in contact with the adhesive.

A shielding device for shielding against weather influences that includes a textile sheet material which is stretched two-dimensionally or can be rolled out and which forms a shield against weather influences, in particular, against solar radiation and/or rain. The textile material has warp threads and weft threads connected together in a lattice-like manner so as to form a fabric. A foam layer which has foam pores that are separated from one another by solid foam walls is applied onto the textile sheet material on at least one side of the textile sheet material.

Provided is a display device using an adhesion control layer, which has excellent scratch-resistance, easily discharges air bubbles, allows proper attachment and detachment, and is stably attached regardless of whether a surface is flat or curved. The device comprises: an adhesive member; an adherend member to which the adhesive member is attached; a detachable layer disposed on one of the adhesive member and the adherend member; and an adhesion control layer to which the detachable layer is detachably attached and which is disposed on one of the adhesive member and the adherend member. The adhesion control layer is disposed on one surface of one of the adhesive member and the adherend member and includes a flat layer covering the whole of the surface and a pattern layer disposed on the flat layer, and the flat layer and the pattern layer have different adhesive forces with respect to the detachable layer.

Optical bodies are described. In particular, optical bodies having a birefringent multilayer optical film and a continuous adhesive layer with a thickness less than 20 micrometers are described. Optical bodies described herein exhibit reduced occurrence and severity of a non-uniformity defect known as “orange peel.”
