Problems solved by technology

[0003] Two methods can be used to attach the auxiliary panel to the display panel. The first is to use solid transparent glue to adhere the auxiliary panel to the display panel, but this method is easy to generate air bubbles between the display panel and the auxiliary panel; The second is to use glue to adhere the auxiliary panel to the display panel, but the disadvantage of this method is that due to the fluidity of the glue, it is difficult to control the diffusion of the transparent liquid glue, and it is easy to produce the defect of overflowing glue

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with examples. The examples are only preferred embodiments of the present invention and are not intended to limit the present invention.

[0022] Dispensing is a process, also called sizing, gluing, potting, dripping, etc. It is to apply glue, oil or other liquids, potting, and dripping on the product to make the product stick, seal, Insulation, fixation, smooth surface, etc.

[0023] During the processing of the touch display module, it is often necessary to connect the display panel and auxiliary panels such as the touch panel and the cover plate bonded to the display panel by dispensing glue. After dispensing, the product is processed by curing. However, during glue dispensing, since glue will flow, it is easy to cause glue overflow around the display panel and the auxiliary panel.

[0024] Based on the above problems, the present invention provides a glue dispensing method for a touch display module fo...

Abstract

The invention discloses a glue-dispensing and laminating method for a touch display module. The method comprises the following steps: S1, providing a first substrate and a second substrate; S2, dispensing a glue on the laminating surface of the first substrate to form a rubber ring at the edge of the laminating surface of the first substrate; S3, pre-curing the glue ring; S4, dispensing the glue on the laminating surface of the first substrate and the inner surface formed by the rubber ring; S5, laminating the first substrate and the second substrate; S6, pre-curing the glue-dispensed area obtained in step S4; and S7, carrying out full-surface main curing on the laminated first substrate and second substrate to completely cure the glue between the first substrate and the second substrate.In the invention, the glue is dispensed on the laminating surface of the first substrate to form the rubber ring at the edge of the laminating surface of the first substrate, the rubber ring is pre-cured, the glue is dispensed on the inner surface formed by the rubber ring, and the glue flows in the area formed by the glue ring, so the method can effectively avoid the problem of glue spilling in the laminating process.

Description

Technical field [0001] The present invention relates to the technical field of touch display, in particular to a glue dispensing method for a touch display module. Background technique [0002] Many display devices (for example, mobile phones, tablet computers, etc.) usually include a display panel and auxiliary panels such as a touch panel and a cover plate adhered to the display panel. [0003] Two methods can be used to attach the auxiliary panel to the display panel. The first is to use solid transparent glue to adhere the auxiliary panel to the display panel, but this method is easy to generate bubbles between the display panel and the auxiliary panel; The second is to use glue to adhere the auxiliary panel to the display panel, but the disadvantage of this method is that it is difficult to control the spread of the transparent liquid glue due to the fluidity of the glue, and it is easy to cause the defect of glue overflow. [0004] Therefore, how to prevent defects when the di...
