Process and structure for adhering electronic paper and touch screen

Abstract

The invention discloses a process for adhering electronic paper and a touch screen. The process comprises the steps of (1) adhering: adhering and fixing an electronic paper body and the touch screen by using a COF adhesive; (2) vacuum heating and adhering: heating and adhering the adhered product in step (1) under the vacuum environment; (3) ultraviolent curing: performing ultraviolent curing on the vacuum heated product. According to the process for adhering the electronic paper and the touch screen, the COF adhesive is taken as the adhesive, so that the clarity and the highlight degree are high, the adhesive power is high, and the water resistance and high-temperature resistance are excellent; the weather resistance is excellent, and the adhered product is not yellowed after being used for a long term; the electronic products are adhered by the COF adhesive, so that the problems that the water resistance of an adhered product is not up to standard after glue is squeezed out, and the electronic paper adhered by an OCA adhesive generates white points can be completely solved; furthermore, the adhesive membrane can be removed any time; the yield is high, and the adhering process is simple; the process is not only suitable for adhering the electronic paper and the touch screen, but also suitable for adhering the electronic paper and other electronic elements.

Description

technical field [0001] The invention relates to an electronic paper bonding process that can improve the bonding yield of electronic paper and TP. In addition, the invention also relates to an electronic paper bonding structure obtained through the electronic paper bonding process, which belongs to the field of electronic display technology . Background technique [0002] With the rapid development of technology and the increasing pressure of environmental protection, people are more and more eager for a medium that combines the dual advantages of traditional paper and modern digital technology. Therefore, electronic paper technology has emerged and developed vigorously. However, in the existing electronic paper products, most of the bonding between the electronic paper body and the TP (Touch Panel, touch screen) uses water glue or OCA optical glue (Optically Clear Adhesive). Since the frame of the electronic paper product is very narrow, Moreover, a certain width must be r...

Problems solved by technology

However, in the existing electronic paper products, most of the bonding between the electronic paper body and the TP (Touch Panel, touch screen) uses water glue or OCA optical glue (Optically Clear Adhesive). Since the frame of the electronic paper product is very narrow, Moreover, a certain width must be reserved around it to seal the waterproof glue. When using water glue for lamination, glue overflow often occurs, so water glue cannot meet the bonding process requirements of electronic paper. For OCA optical glue, due to its It is easy to produce white spots after laminating and baking, which affects the quality of the product
