Embodiment 1

[0058] The size of the display surface of the display panel 1 is 42 inches, that is, the corresponding N=42, the display panel 1 is a TFT display panel, and the display panel includes a first polarizer stacked in sequence, a first substrate, a liquid crystal layer, a light filter sheet, a second substrate, and a second polarizer (not shown in the figure). The touch panel 3 includes a sensing layer 31 , an adhesive layer 32 and a transparent cover 33 stacked in sequence, wherein the solid optical adhesive layer 2 to be used is an OCA adhesive layer.

[0059] The bonding process of touch display components includes:

[0060] use the formula Calculate the thickness of the OCA adhesive layer to be used, where N=42, a=0.1mm, and the calculated T=0.6083mm.

[0061] An OCA adhesive layer with a thickness of 0.6078 mm is disposed on the surface of the sensing layer 31 of the touch panel 3 away from the adhesive layer 32 to form a pre-lamination structure 4 .

[0062] Such as ima...

Embodiment 2

[0066] The difference from Example 1 is that a=0, and the calculated T=0.5083mm.

Embodiment 3

[0068] The difference from Embodiment 1 is that the size of the display surface of the display panel is 66 inches, that is, corresponding to N=66, a=-0.1mm, and T=0.5187mm obtained through calculation.

Abstract

The present application provides a touch display component and a bonding method thereof. The touch display component includes: a display panel, a solid optical adhesive layer and a touch panel stacked in sequence, and the thickness of the solid optical adhesive layer, wherein, N is the inch corresponding to the length of the diagonal of the display surface of the display panel Number, N≤98, ‑0.1mm≤a≤0.1mm. The thickness of the solid optical adhesive layer in the touch display component is calculated by the formula. By controlling the size of a and N, the solid optical adhesive layer of this thickness can not only ensure the touch display component has a better display effect, Moreover, it has a strong peeling force, which ensures the fastness of bonding between the touch panel and the display panel.

Description

technical field [0001] The present application relates to the field of touch display components, in particular, to a touch display component and a bonding method thereof. Background technique [0002] With the development of commercial displays, the requirements for the visual effects of displays are getting higher and higher, and the large-screen full-fit touch market has great room for development. [0003] The fully bonded display touch display component mainly includes a touch panel (Touch Panel, TP for short), optical adhesive and display panel, and the touch display component interacts with the host to realize touch control. Among them, how to fully bond the touch panel and the display panel is undoubtedly the most important part of the manufacturing process. [0004] At present, the large-size (42-98 inches) full lamination technology on the market mainly uses liquid optical glue for full lamination. Generally, a retaining wall is surrounded around the four sides of ...
