A touch screen laminating method capable of reducing pressing water ripples and a touch screen

Abstract

The invention provides a touch screen laminating method capable of reducing pressing water ripples, which comprises the following steps: S1, water glue layer coating: coating a water glue layer on thelower side surface of an induction layer, and arranging a cover plate layer on the upper side surface of the induction layer; S2, semi-curing the water glue layer; S3, binding the TN screen and the water glue layer together through a laminating machine; S4, putting the semi-finished product obtained in the step S3 into a defoaming machine for defoaming; S5, enabling the water glue layer to be completely cured; And S6, glue sealing: sealing an edge area between the water glue layer and the TN screen layer with OCA optical glue to obtain a finished product. Before the TN screen and the induction layer are attached, the lower side of the induction layer is coated with the water glue layer; The water glue layer can play a role in supporting and buffering pressure after being semi-cured and completely cured, so that the TN screen layer can be prevented from generating water ripples under the action of pressure, the touch screen which is not easy to generate the water ripples can be produced by using the touch screen laminating method disclosed by the invention, meanwhile, the production cost is reduced, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a touch screen bonding method and a touch screen that can reduce water ripples when pressed. Background technique [0002] An existing structure of a touch screen that can reduce water ripples when pressed is as follows: from bottom to top, it includes a hard screen layer, a sensing layer, and a cover layer. The hard screen layer is generally an STN hard screen or an IPS hard screen. The liquid crystal molecules in this type of hard screen are horizontal, and can maintain the original picture when it is under external pressure, but this type of hard screen is expensive, and the cost of the touch screen produced by using it is relatively high, so there are many alternatives. Among them, the TN screen has become the first choice to replace the hard screen due to its excellent performance and low price, that is, the TN screen is directly pasted on the lower side of the sensing...

[0002] An existing structure of a touch screen that can reduce water ripples when pressed is as follows: from bottom to top, it includes a hard screen layer, a sensing layer, and a cover layer. The hard screen layer is generally an STN hard screen or an IPS hard screen. The liquid crystal molecules in this type of hard screen are horizontal, and can maintain the original picture when it is under external pressure, but this type of hard screen is expensive, and the cost of the touch screen produced by using it is relatively high, so there are many alternatives. Among them, the TN screen has become the first choice to replace the hard screen due to its excellent performance and low price, that is, the TN screen is directly pasted on the lower side of the sensing layer to replace the hard screen. When the pressure is high, especially when the pressure is high, the liquid crystal molecules will sink into an inverted splayed shape, resulting in water ripple-like afterimages in the touch screen and affecting product quality. Therefore, it is necessary to improve the bonding process and structure of the existing touch screen. Improve product quality and reduce production costs
