Problems solved by technology

[0003] However, when the touch display device is exposed to high temperature for a long time, such as in an environment of 80 to 85 degrees Celsius for up to 1000 hours, the solidified adhesive layer may melt into a liquid
When the adhesive layer melts into a liquid, the liquid optical glue may flow to the display panel of the display module through the opening of the sealant and damage the display panel
In addition, air may also enter the adhesive layer through the opening of the sealant to fill the gap caused by the outflow of the optical glue, thereby causing air bubbles to appear on the appearance of the touch display device.

Abstract

The invention discloses a touch display device. The touch display device comprises a display module, a touch panel, a first sealant, an adhesive layer and a second sealant. The touch panel is stacked on one side of the display module. The first sealant is clamped between the display module and the touch panel and comprises a sealing section and two protruding sections. The display module, the touch panel and the sealing section jointly form an accommodating space. The two protruding sections protrude from the sealing section in the direction away from the accommodating space to jointly form an opening communicated with the accommodating space. The adhesive layer is located in the accommodating space and enables the display module to be connected to the touch panel. The second sealant is connected to the two protruding sections to seal the opening and the accommodating space.

Description

technical field [0001] The present invention relates to a touch display device, in particular to a touch display device including an adhesive layer. Background technique [0002] Generally speaking, a touch display device includes a touch panel and a display module, and due to cost considerations, the touch panel and the display module are usually joined by an adhesive layer formed after curing of Liquid Optically Clear Adhesive (LOCA). Moreover, a sealant is generally provided between the touch panel and the display module, so that the liquid optical glue is injected into the accommodation space surrounded by the sealant through the opening of the sealant to cure the liquid optical glue. In addition, before the liquid optical adhesive is cured into an adhesive layer, the excess air in the accommodation space surrounded by the sealant will be drawn out through the opening of the sealant to ensure the reliability of bonding the touch panel and the display module with the adhe...
