Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings but not all of them.

[0020] figure 1 It is a schematic structural diagram of a curved display device provided by an embodiment of the present invention. Such as figure 1 As shown, the curved display device provided in this embodiment includes: a curved display panel 110 and a plurality of stacked external components 120 on the curved display panel 110 . In this embodiment, two external components are stacked as an example for illustration. The curved display device is bent toward the external component side, that is, the corresponding curvat...

Abstract

The embodiment of the invention discloses a curved-surface display device. The curved-surface display device comprises a curved-surface display panel and multiple laminated external components which are located on the curved-surface display panel; the external components are bonded through adhesive layers, and the external components are bonded with the curved-surface display panel through adhesive layers; and elasticity modulus of the adhesive layers subjected to tensile stress is larger than that of the adhesive layer subjected to pressure stress, and/or adhesive force of the adhesive layers subjected to the pressure stress is larger than that of the adhesive layers subjected to the tensile stress. According to the curved-surface display device, stress damage of the curved-surface display device in the one-way bending process is effectively avoided, and the thickness of the curved-surface display device can be reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a curved display device. Background technique [0002] A curved display device refers to a flexible flat panel display device prepared on a flexible substrate such as plastic, metal sheet or glass sheet. The laminated structure of the curved display device is generally that the functional film layers are bonded together through adhesive layers. When bending in one direction, the functional film layers of the curved surface display device are bounded by the neutral plane of force, and the film layers pointing to the center of curvature along the neutral plane of force are subjected to compressive stress, and the film layers along the neutral plane of force are away from the center of curvature. The film layer is subjected to tensile stress. Due to the bending of the curved surface display device, the film layer in the state of compressive stress is prone to separation, while th...
