Ultrathin double-sided nano-silver capacitive screen and preparation method thereof

Abstract

The invention relates to the field of capacitive screens, in particular to an ultrathin double-sided nano-silver capacitive screen and a preparation method thereof.The ultrathin double-sided nano-silver capacitive screen comprises a double-sided nano-silver film, an OCA adhesive layer and a glass cover plate, and the double-sided nano-silver film and the OCA adhesive layer are both single layers.The preparation method of the ultrathin double-sided nano-silver capacitive screen comprises the steps that the OCA adhesive layer is attached to the double-sided nano-silver film in a roll-to-roll mode, and the double-sided nano-silver film is covered with the glass cover plate. According to the ultrathin double-sided nano-silver capacitive screen, the technological process is simplified, the production period is short, mechanical work is set, the low yield caused by manual misoperation is reduced, and the overall cost is reduced. Meanwhile, the thickness of the capacitive screen is reduced,and the touch experience effect is improved.

Description

technical field [0001] The invention relates to the field of capacitive screens, in particular to an ultra-thin double-sided nano-silver capacitive screen and a preparation method thereof. Background technique [0002] The traditional nano-silver capacitive screen is generally set as a double-layer single-sided nano-silver film, such as figure 1 As shown, from bottom to top are the first single-sided nano-silver film 11, the first OCA adhesive layer 12, the second single-sided nano-silver film 13, the second OCA adhesive layer 14 and the glass cover plate 15, the double-layer nano-silver Film and OCA adhesive layer make the thickness of the capacitive screen too large, the touch sensitivity is low, and the experience is poor. In addition, in the preparation process of a capacitive screen containing a double-layer nano-silver film, the single-sided nano-silver film must be cut into slices and then laser-etched. Using manual lamination technology requires at least 4 manual pr...

[0002] The traditional nano-silver capacitive screen is generally set as a double-layer single-sided nano-silver film, such as figure 1 As shown, from bottom to top are the first single-sided nano-silver film 11, the first OCA adhesive layer 12, the second single-sided nano-silver film 13, the second OCA adhesive layer 14 and the glass cover plate 15, the double-layer nano-silver Film and OCA adhesive layer make the thickness of the capacitive screen too large, the touch sensitivity is low, and the experience is poor

In addition, in the preparation process of a capacitive screen containing a double-layer nano-silver film, the single-sided nano-silver film must be cut into slices and then laser-etched. Using manual lamination technology requires at least 4 manual processes, and it is also necessary to ensure that the two-layer single-layer There is no scratch on the nano-silver film on the surface, otherwise it may lead to poor contact and the product will be scrapped

The production efficiency is low, and the number of product stacking layers is large, and the process is cumbersome, resulting in low product yield and high cost
