Description

Toughened glass film suitable for ultrasonic fingerprint unlocking under screen

Technical Field

The utility model relates to the technical field of toughened films, in particular to a toughened glass film suitable for under-screen ultrasonic fingerprint unlocking.

Background

The existing mobile phone market screen fingerprint unlocking has various schemes, such as screen optical fingerprint unlocking, screen ultrasonic fingerprint unlocking and the like

The mobile phone unlocked by the optical fingerprint under the screen is easy to adapt to a toughened film or a protective film. Or the fingerprint unlocking effect cannot be influenced by pasting the mobile phone film or pasting the toughened film. The common protective film or the toughened glass film of the mobile phone can be normally used.

And another under-screen ultrasonic fingerprint unlocking technology is adopted by flagship models of some brands such as samsung S10 samsung S10+ at present, and the fingerprint unlocking function cannot be used when the mobile phones are attached with common toughened glass films. In the current market, the toughened glass film for the mobile phones does not solve the problem.

At present, through continuous attempts and verifications, the toughened glass film capable of solving the problem is developed.

The problem of fingerprint unlocking can be solved by the toughened glass film scheme of the ultrathin glass and the ultrathin AB glue.

Detailed Description

The following description is presented to disclose the utility model so as to enable any person skilled in the art to practice the utility model. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

In order to solve the technical problem that the traditional tempered film cannot identify fingerprints by adopting an ultrasonic fingerprint unlocking machine type, as shown in fig. 1 to 6, the following technical scheme is provided:

the utility model provides a toughened glass film of ultrasonic fingerprint unblock under suitable screen which characterized in that, includes AF coating film layer 1, toughened glass layer 2, adhesive layer 3 that top-down set up and leaves type rete 4, adhesive layer 3 is including the first adhesive layer 5 and the second adhesive layer 6 that top-down set up, first adhesive layer 5 and the laminating of toughened glass layer 2, second adhesive layer 6 with leave the laminating of type membrane.

Specifically, when needs use the tempering membrane, operating personnel will treat the cell-phone surface of pad pasting at first clean through burnishers such as alcohol, then take the tempering membrane and tear tempering membrane from type rete 4 with the second adhesive layer 6 of tempering membrane by the way, then be located the tempering membrane directly over the cell-phone, make the long limit of tempering membrane and minor face direction and the long limit and the minor face direction of treating the pad pasting collection be flush and parallel arrangement each other, at last with the tempering membrane attached to the cell-phone surface, thereby accomplish the attached work to the tempering membrane.

Further, in order to solve the technical problem of how to make the tempered glass layer 2 have a certain adhesion, as shown in fig. 4 and 5, the following technical solutions are provided:
