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 present invention provides a curved display panel bonding device, which solves the technical problem of uneven distribution of curved surface bonding pressure, resulting in black spots on the display body or other poor display. The curved surface bonding device provided by the embodiment of the present invention adopts bonding rollers and at least one layer of supporting rollers to roll the display substrate and the curved surface cover to achieve bonding. When the curved surface cover is bonded to the display substrate, the supporting rollers The set and fitting rollers can carry greater fitting pressure without bending, thereby increasing the fitting pressure during the fitting process, so even if the diameter of the fitting roller is small, it can also ensure the tightness during the fitting process Fitting pressure is high. It can not only ensure a large bonding pressure during the bonding process, but also ensure that the diameter of the bonding roller is small, which improves the uniformity of pressure during the bonding process and avoids the display caused by uneven distribution of bonding pressure There are black spots or other poor display problems on the screen.

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...
