Embodiment Construction

[0048] In the production process of the existing curved screen, the screen body is usually bonded to the cover plate by using a bonding device. When bonding, because the bonding device is in contact with the screen body, the pressure in the middle of the screen body is greater than that of the screen body. The pressure on the edge, the pressure on the edge of the screen body cannot meet the bonding requirements, that is, the bonding force between the screen body and the cover plate of the curved screen is uneven, which leads to black spots, bubbles and other bonding effects on the curved screen. Therefore, the existing display screen has the problem of poor bonding effect between the screen body and the cover plate.

[0049] In view of the above defects, the embodiment of the present invention provides an improved technical solution. In this technical solution, the curved screen bonding device includes a base, an elastic component, a backing plate and a flexible pressing mold. ...

Abstract

The invention provides a curved screen attaching device, and relates to the technical field of display. The curved screen attaching device comprises a base, an elastic assembly, a base plate and a flexible pressing die, wherein the base plate is arranged above the base; the elastic assembly is connected with the base plate and the base; the flexible pressing die covers the base plate; the top of the flexible pressing die is provided with an arc surface adaptive to the shape of a screen body; the base comprises a main body and two side beams connected to the two sides of the main body; the sidebeams are higher than the main body in the vertical direction; the side beams are provided with grooves and supporting parts in the length direction of the side beams; and the two sides of the flexible pressing die extend outwards to cover the supporting parts and extend into the grooves. The problem of poor attaching effect of the screen body and a cover plate in the prior art is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a curved screen bonding device. Background technique [0002] With the development of display technology, users have gradually diversified display requirements for display screens. In order to obtain a better visual experience, display screens will gradually develop in the direction of curved surfaces. During the manufacturing process of the curved screen, the screen body needs to be bonded to the cover plate. In the prior art, a bonding device is usually used to bond the screen body to the cover plate. [0003] Due to the uneven force applied to the screen body by the existing bonding device during bonding, the bonding force between the screen body and the cover plate is uneven, resulting in problems such as black spots and air bubbles on the curved screen. Therefore, the existing curved screen has the problem of poor bonding effect between the screen body and the cover plate....
