Method for adhering touch screen and display panel

Abstract

The invention provides a method for adhering a touch screen and a display panel. The method comprises the following steps of adhering a frame sealant on the display panel, wherein the sealant a containing cavity is defined on the display panel by the sealant; pouring glue inside the containing cavity defined on the display panel by the sealant; and pressing the touch screen towards one surface of the display panel, which is poured with the glue, so as to press and adhere the touch screen and the display panel. According to the method, the touch screen and the display panel can be exchanged. According to the method provided by the invention, the interval thickness after the touch screen and the display panel are adhered is limited by the thickness of the frame sealant, so that the adhering thickness for each time is uniform. Furthermore, an operator can conveniently control the pouring amount of the glue through the limitation of the frame sealant, so that the pouring amount of the glue can be controlled well; the overflowing glue after an adhering process can be greatly reduced; and the workload caused by wiping the overflowing glue can be greatly reduced.

Description

technical field [0001] The invention relates to a method for bonding two flat parts, in particular to a method for bonding a touch screen and a display panel. Background technique [0002] Mobile phones, computers and other electronic products are widely used. In order to facilitate user operations, the keyboards of mobile phones and computers are gradually replaced with touch screens. [0003] The touch screen of electronic products such as mobile phones and computers is usually attached to the display panel. At present, there are two ways to attach the touch screen and display panel, one is frame adhesive bonding, and the other is OCA (Optical Clear Adhesive, optically transparent adhesive) Or OCR (Optical Clear Resist, optically transparent resin glue, also known as "water glue") direct full fit. [0004] The frame glue used in the bonding method of the frame glue has a certain thickness, and there will be a gap filled with air between the touch screen and the display pa...

AI Technical Summary

Problems solved by technology

But because of the fluidity of the water glue, when the touch screen and the display panel are fully bonded, air bubbles are likely to be formed in the middle. In order to completely rely on the flow of the glue to realize the bubble extrusion, it is necessary to use a large amount of water glue, and the water glue When the amount is large, there will be more glue overflowing on the edge after the touch screen and the display panel are bonded before curing, and the glue must be wiped manually, and the thickness of the glue layer is not easy to control, it is difficult to achieve a uniform thickness, and the glue making process is troublesome , and waste more glue
