Problems solved by technology

However, the OCA optical tapes that are common in the market mostly use PET, tissue paper, etc. as the base material, so two coatings are required to complete the production of OCA optical tapes, which not only consumes more man-hours and production costs; especially, the relative increase Possible contamination of the tape

Embodiment Construction

[0036] As shown in the enlarged schematic view of the structure of the substrate-less optical tape of the present invention in Figure 1, the substrate-free optical tape of the present invention is covered with a first release film 20 with a predetermined thickness on both sides of an optical film 10 with a predetermined thickness, and A second release film 30 with a predetermined thickness. Wherein, the optical film 10 is formed by curing a pre-synthesized adhesive material and a film-forming formula of a predetermined weight percentage by UV light; Joint agent, and antioxidant composition.

[0037] As for, the film-forming formulation may have a predetermined weight percentage of photoinitiator. The first release film can be a heavy release film with a thickness of 125 mic; the second release film is a light release film with a thickness of 50 mic, so that the overall substrate-free optical adhesive tape can achieve better structural strength , and can be stored at room tem...

Abstract

The invention provides a base material-free optical adhesive tape and its manufacturing method. The method consists of: firstly adding a film-forming ingredient into a pre-synthetic adhesive material, conducting stirring to obtain a liquid optical adhesive, also providing a first release film transferred at a predetermined speed, when the first release film moves, coating a liquid optical adhesive with a predetermined thickness on the first release film at the same time, then carrying out UV illumination curing and maturation processing on the liquid optical adhesive on the first release film in order so as to form an optical film with a predetermined thickness, then providing a second release film and using it to cover the cured optical film, thus obtaining the base material-free optical adhesive tape that has a predetermined thickness optical film with both sides covered by the first release film and the second release film respectively.

Description

technical field [0001] The present invention relates to an optical adhesive tape, and aims to provide a substrate-less optical adhesive tape and a related manufacturing method thereof. Background technique [0002] In today's information age, human beings are increasingly dependent on electronic products. Electronic products such as notebook computers, mobile phones, personal digital assistants (PDAs), and digital walkmans have become indispensable in modern people's life and work. Indispensable application tools. In addition to having a display, the above-mentioned electronic products must also provide a man-machine interface for the user to communicate with the internal system of the electronic product. [0003] With the user's requirements for the display quality, convenience and friendliness of the display, a touch panel is installed on the display panel, and the traditional input device such as a button or a mouse is replaced by the touch panel, which provides A way f...
