Example Embodiment

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the optical clear glue and the preparation method of the optical clear glue provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0031] The embodiment of the present invention provides an optical transparent glue, which combines figure 1 with figure 2 As shown, the optical clear adhesive includes an optical clear adhesive layer 1 and a first release film 2. The first release film 2 is pressed on one side of the optical clear adhesive layer 1 (ie, the first surface 11), and the first release film A first protrusion 3 is provided on the side of the molded film 2 adjacent to the optically transparent adhesive layer 1, and a first groove 4 is formed at a position corresponding to the optically transparent adhesive layer 1 and the first protrusion 3.

[0032] Specifically, the optically transparent adhesiv...

Abstract

The invention provides an optical transparent adhesive tape and a preparation method for the optical transparent adhesive tape. The optical transparent adhesive tape comprises an optical transparent adhesive tape layer and a first release film, wherein the first release film is pressed on one side of the optical transparent adhesive tape layer; a first bulge is arranged on one side of the first release film adjacent to the optical transparent adhesive tape layer; a first groove, the shape of which is as same as the shape of the first bulge, is formed on one side of the optical transparent adhesive tape layer; when the side of the optical transparent adhesive tape layer with the first groove is adhered to a display panel, air between the optical transparent adhesive tape layer and the display panel can flow along the first groove, so that air can be conveniently exhausted, the air bubbles between the optical transparent adhesive tape layer and the display panel can be correspondingly reduced and the optical performance of the display module can be promoted. After the optical transparent adhesive tape layer is bonded with the display panel, the optical transparent adhesive tape layer has certain liquidity and the optical transparent adhesive tape layer can be conformed to the surface of the display panel, so that the optical performance of the display module can be further promoted.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical transparent adhesive and a preparation method of the optical transparent adhesive. Background technique [0002] Optical Clear Adhesive (OCA) has the advantages of high light transmittance, high bonding strength, can be cured at room temperature, and has small curing shrinkage, so it is widely used in the bonding of touch panels and display panels. combine. The optically transparent adhesive includes an optically transparent adhesive layer, a first release film and a second release film, and the first release film and the second release film are respectively pressed on both sides of the optically transparent adhesive layer. In the bonding process of the panels, the first release film is first peeled off from the optically transparent adhesive layer, and then the display panel is bonded to the optically transparent adhesive layer, and then the second release film is p...
