Laminating method and laminating device

Abstract

The invention discloses a laminating method, which is used for laminating a flexible display panel and a cover plate, and comprises the following steps of: arranging the cover plate on one side of theflexible display panel; carrying out plane fitting on the flexible display panel and the cover plate; softening the preset position of the cover plate; arranging a first jig on one side, deviating from the cover plate, of the flexible display panel, and arranging a second jig on the side, away from the flexible display panel, of the cover plate, wherein the projection of the first jig on the flexible display panel corresponds to the projection of the second jig on the cover plate, and a curved surface structure is formed on one side of the first jig; and driving the second jig to be bent around the softened preset position in the direction close to the first jig, so that the cover plate is controlled to form a bent area matched with the curved surface structure, and the first jig is contained in the bent area. According to the invention, the product yield and the display effect are improved.

Description

technical field [0001] The invention relates to the field of display technology. More specifically, it relates to a bonding method and a bonding device. Background technique [0002] With the development of science and technology, curved screens are becoming more and more popular. Curved screens generally include a cover and a flexible display panel that fits the cover. The cover can be a cover with both ends bent inward. plate, and the flexible display panel is attached to the inner side of the cover plate. [0003] In the related art, the flexible display panel and one side of the cover are pre-formed with a bending area. The bonding machine draws the gap between the flexible display panel and the cover to be hollow to realize the lamination of the flexible display panel and the cover. In the process of laminating the flexible display panel and the cover, the following two methods are generally used: : [0004] (1) if figure 1 As shown, the scroll wheel 400 is used to...

Problems solved by technology

[0004] (1) if figure 1 As shown, the scroll wheel 400 is used to scroll along the surface of the flexible display panel 100 (in figure 1 In the example, the roller 400 rolls along the X direction) to compress the flexible display panel 100 and the cover plate 200, but because the inner space formed by the bending area 201 of the flexible display panel 100 is narrow, thus The diameter of the restricting roller 400 is small, resulting in insufficient pressure on the roller 400, which may cause local compaction failure;

[0005] (2) if figure 2 As shown, the lamination is carried out by using a profiling jig, for example: using the slider 500 to slide on the surface of the flexible display panel 100 to compact the bending area 201 of the flexible display panel 100 (in the figure 2 In the example, the slider 500 slides along the X direction), and at the same time, the support block 600 matching the curved surface of the flexible display panel 100 is used to compact the non-bending area of ​​the flexible display panel (in figure 2 In the example shown above, the support block 600 compresses the flexible display panel 100 along the Y direction), but the design of the mechanism is complicated, and it is difficult to control during the bonding process, and the slider 500 is prone to cause flexibility during the sliding process. Problems such as cracks on the display screen 100 and air bubbles between the flexible display panel 100 and the cover plate 200 affect the product yield and display effect of the curved screen
