Problems solved by technology

In addition, process parameters such as the material and composition of the curved glass cover, and the thermoforming temperature may also destroy the stability of the curvature.
[0006] On the other hand, after the curved glass cover and the flat display module are bonded by Optically Clear Adhesive (OCA), the flat display module has a rebound force due to physical bending deformation, and this rebound force reacts on the curved surface through the OCA glue. The glass cover is also prone to instability in the shape and size of the curved glass cover

Embodiment Construction

[0028] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0029] Please also see figure 1 and figure 2 , the present invention firstly provides a curved glass cover, including a body 11 and at least one reinforcement 13 . The upper and lower surfaces of the body 11 are both curved surfaces with a certain curvature, and the reinforcing member 13 is fixed on the body 11 along the direction of curvature change of the body 11 to limit the plastic rebound of the body 11 in the direction of curvature change , to play a role in resisting the rebound of the body 11 .

[0030] Preferably, the number of the reinforcement 13 is two, and the two reinforcements 13 are respectively fixed on the two side edges of the body 11 along the direction of curvature change of the body 11 to jointly limit the plastic rebo...

Abstract

The present invention provides a curved glass cover plate and a curved liquid crystal display apparatus. The curved glass cover plate comprises a body (11) and at least one reinforcer (13), the reinforcers (13) are fixed on the body (11) in a curvature change direction of the body (11) and restrict plastic resilience of the body (11) in the curvature change direction, so that influence of internal stress can be eliminated, and the curved glass cover plate can be provided with stable curvature profile and dimension. According to the curved liquid crystal display apparatus, a liquid crystal display module group (5) is attached to the curved glass cover plate (1) having the reinforcers (13), the curved glass cover plate (1) and the liquid crystal display module group (5) have stable curvature profiles and dimensions under the effect of the reinforcers (13), so that requirements of curved display on product profile and dimension can be easily satisfied, an intelligent terminal product can be assembled stably, and the structure is reliable.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a curved glass cover plate and a curved liquid crystal display device. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or laptop screen, etc. [0003] With the development of display technology, more and more small and medium-sized smart terminal curved liquid crystal display devices appear. Generally speaking, a curved liquid crystal display device is a flat liquid crystal display module bonded to a curved glass cover with a certain curvature change on the upper and lower surfaces, and the flat liquid crystal display module adopts physical bending (bending) to form the curvature . [0004] The molding process of the curved glass cover plate gener...
