Embodiment Construction

[0020] As mentioned in the background art, in the prior art, the pressure distribution of curved surfaces is uneven, which leads to black spots on the display screen or other technical problems of poor display. The inventor found that the reason for this problem is that when the rollers are used in the lamination process, due to the existence of the curved angles, the compression and lamination of the rollers at the curved corners is not easy to achieve, that is, if the curved corners are bonded, it is necessary to The smaller the diameter of the roller, the better, but if the curved corner is pressed tightly, the greater the pressure that the roller exerts on the fitting place, the better, but the greater the pressure, the larger the diameter of the roller is required, so for the fitting of the curved corner, Both lamination and compression are required, and the diameters of the rollers that need to be used are contradictory. Therefore, in the prior art, it is impossible to sa...

Abstract

The embodiment of the invention provides a laminating device for a curved surface display panel. The laminating device solves the technical problems that black spots or other undesirable display appear on display screen bodies due to uneven distribution of curved surface laminating pressure. Laminating can be achieved by using a laminating roller and at least one layer of support roller group to roll and press a display substrate and a curved surface cover plate, when the curved surface cover plate and the display substrate are laminated, the at least one layer of support roller group and the laminating roller can bear a larger laminating pressure to avoid curving, so that the laminating pressure in the laminating process can be increased; even if the diameter of the laminating roller is smaller, the greater laminating pressure in the laminating process can also be ensured; and the laminating device not only can ensure that the laminating pressure in the laminating process is greater, but also can ensure that the diameter of the laminating roller is smaller, improves the pressure uniformity in the lamination process, and solves the problems that the black spots or other undesirable display appear on the display screen bodies due to uneven distribution of the curved surface laminating pressure.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a curved display panel bonding device. Background technique [0002] Flexible display panel technology is now the mainstream display panel technology. Flexible display panels on the market are mainly used in terminals with curved edges. In the current lamination method, the lamination pressure is unevenly distributed. During the lamination process, the display substrate and cover Bubbles are generated between the boards, causing black spots or other poor display problems on the display panel. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a curved display panel laminating device, which solves the technical problem of uneven distribution of curved surface laminating pressure, resulting in black spots on the display screen or other display defects. [0004] In order to make the purpose, technical means and advantages of the p...
