Problems solved by technology

Since the height of the sealant 130 is smaller than the gap G between the touch panel 120 and the display panel 110 before lamination, if too much water glue 140 is applied, the water glue 140 will fall from above the sealant 130 during the lamination process. overflow, and the gas between the display panel 110 and the touch panel 120 is difficult to completely discharge, and it is easy to form air bubbles, thereby reducing the production yield of the touch display device 100
[0004] On the other hand, if the water glue 140 is applied too little and not completely coated in the glue spreading area 112 of the first substrate 110, the bonding effect between the first substrate 110 and the second substrate 120 will also be affected.

Abstract

A frame glue structure is arranged between a first base plate and a second base plate. The first base plate is provided with a glue spreading region, a frame glue coating region and an overflowing glue region. The frame glue coating region surrounds the glue spreading region, and the overflowing glue region is located on the outer side of the frame glue coating region. The second base plate covers above the frame glue coating region and the glue spreading region. The frame glue structure is located in the frame glue coating region of the first base plate and contacts with the second base plate. The frame glue structure comprises inner frame glue and outer frame glue, and a first flow guiding channel for communicating the glue spreading region with the overflowing glue region is arranged between the inner frame glue and the outer frame glue. The frame glue structure can increase yield of a gluing procedure.

Description

technical field [0001] The present invention relates to a sealant structure, and in particular to a sealant structure which can improve the yield rate of lamination process. Background technique [0002] In the atmospheric bonding process of the touch display device, it is usually necessary to use water glue and frame glue to bond the two substrates together. figure 1 It is a schematic cross-sectional view of an existing touch-sensitive display device in a bonding process. Figure 2A for figure 1 shown on the display panel, Figure 2B Apply frame glue to Figure 2A Schematic diagram of the display panel. see figure 1 , Figure 2A and Figure 2B The bonding process of the touch display device 100 is mainly to form the frame glue 130 in the frame glue coating area 113 of the display panel 110 first, and then place the display panel 110 and the touch panel 120 on the first carrying platform 102 and the first carrying platform 102 respectively. on the second carrying pla...
