Embodiment 1

[0043] This embodiment provides a substrate bonding method, including the following steps:

[0044] setting a light shielding frame in the peripheral area of ​​the surface to be bonded of the first substrate;

[0045] An easily detachable layer is set on the light blocking frame;

[0046] Coating curable glue on the surface to be bonded of the first substrate;

[0047] Pre-cure the curable glue;

[0048] The easy-detachable layer is removed, and the curable glue attached to the easy-detachable layer is removed at the same time.

[0049] In the substrate laminating method, touch display substrate and display device of the present invention, since an easy-to-detachable layer is provided around the first substrate, and then the curable adhesive is applied, the curable adhesive is pre-cured and the easy-to-detachable layer is removed to enable The curable adhesive forms a special-shaped shape, the thickness of the curable adhesive layer is uniform, the surface is smooth, and th...

Embodiment 2

[0078] This embodiment provides a touch display substrate, and the touch display substrate is prepared by using the above-mentioned substrate bonding method.

[0079] Since the touch display substrate of this embodiment is prepared by the above-mentioned substrate bonding method, the optical performance of the touch display substrate is relatively good.

Embodiment 3

[0081] This embodiment provides a display device, and the display device includes a touch display substrate.

[0082] Since the display device of this embodiment includes the above-mentioned touch display substrate, the optical performance of the display device is better.

Abstract

The invention provides a substrate bonding method, a touch display substrate, and a display device. In the substrate laminating method of the present invention, the touch display substrate and the display device are provided with a detachable layer on the periphery of the first substrate, and then coated with a light-curable adhesive. The glue forms a special-shaped shape, the thickness of the light-cured glue layer is uniform, the surface is smooth, and the edge slope angle is close to 90°; at the same time, it can effectively reduce the lamination bubbles, control the lack of glue and glue overflow in the edge area during lamination, and ensure the display device optical performance.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a touch display substrate and a display device with a substrate bonding method. Background technique [0002] Electronic products with display functions such as mobile phones and computer televisions are increasingly widely used. During the manufacturing process, it is usually necessary to bond two substrates with functional layers, for example, bonding a touch screen substrate to a display substrate. [0003] There are generally two bonding processes. One is the frame glue bonding method. The frame glue used has a certain thickness. Taking the touch screen substrate bonded to the display substrate as an example, there will be a gap between the bonded touch screen and the display substrate. Filling the gap with air leads to insufficient bonding between the touch screen and the display substrate, which easily causes particles to infiltrate, and the optical performan...
