Panel and fitting method thereof

Abstract

The invention discloses a panel and a fitting method thereof. The fitting method of the above-mentioned panel includes the following steps of: (1) positioning the first end of the first side of a solid state optical film on one side of a first panel and pressing the first end of the second side of the solid state optical film with a roller; (2) rolling the roller at least once along the second side of the solid state optical film so that the solid-state optical film is attached to the first panel to form a first fit body; (3) positioning the first end of the first side of a second panel on thesecond side of the solid state optical film and pressing the first end of the second side of the second panel through the roller; (4) rolling the roller at least once along the second side of the second panel so that the second panel is attached to the solid state optical film to form a second fit body. With the panel fitting method, the prepared panel has the advantages of being capable reducinga mura phenomenon and bubble phenomenon, being suitable for large sizes, and having simple process, high yield and low cost.

Description

technical field [0001] The invention relates to the technical field of optical panels, in particular to a panel and a bonding method thereof. Background technique [0002] Optical panels usually need to connect two or more panels together by gluing. In the prior art, there are the following methods for panel bonding: [0003] The first is to place the optical adhesive flat on the panel, then place the panel on the SCA, perform high-temperature vacuum lamination at 60°C-90°C, and then defoam. Due to the large stress and large shrinkage of the optical adhesive, macular spots appear on the panel, and even various traces appear due to uneven brightness when the panel displays images, that is, the MURA phenomenon, and the bonding process is complicated, the yield rate is low, and the cost is high. [0004] The second method is to apply water glue on the panel and attach it in parallel. The glue leveling process takes a long time, the glue cost is high, the labor cost is high, an...

Problems solved by technology

Due to the large stress and large shrinkage of the optical adhesive, macular spots appear on the panel, and even various traces appear due to uneven brightness when the panel displays images, that is, the MURA phenomenon, and the bonding process is complicated, the yield rate is low, and the cost is high.

[0004] The second method is to put water glue on the panel and stick it in parallel. The glue leveling process takes a long time, the glue cost is high, the labor cost is high, and the efficiency is low.

[0005] The third is to attach the solid-state optical glue to the panel, and then put the panel and the panel with the solid-state optics into the vacuum for parallel lamination. When the product size is larger, the two surfaces cannot be bonded in parallel. Once there is non-parallel lamination, MURA phenomenon and air bubble phenomenon will appear. This lamination method requires high precision of the equipment, high difficulty in controlling the lamination process, high lamination cost, and limited size
