Problems solved by technology
At present, the sealing of the upper forehead optical distance sensing module of electronic equipment mainly relies on glue dispensing or foam glue sealing, and these two sealing methods require a certain effective width (the narrowest of glue dispensing is 0.60mm, and the narrowest of foam glue is 0.8mm). , the structure limits the limit size of the upper forehead, which affects the appearance of the product

Embodiment approach
[0027] As a preferred embodiment, choose: along the extension direction of the package cover 3, the lap width between the package cover 3 and the first overlapping surface is 0.15mm (such as figure 2 Dimension a), that is, the sealing width of the optical glue 4 between the package cover plate 3 and the front shell 1 is 0.15mm, obviously, it is 0.45mm less than the dispensing seal (0.6mm), and compared with the foam glue The seal (0.8mm) was reduced by 0.65mm.
[0028] On the basis of the above technical solution, as an optional implementation manner, there is a first gap between the light guide column 2 and the front case 1 along the extending direction of the packaging cover plate 3 .
[0029] On the basis of the above technical solution, the optical glue 4 for bonding the package cover plate 3 to the first and second overlapping surfaces has an integrated structure, in other words, the first gap between the light guide column 2 and the front shell 1 Optical glue 4 is also...

The invention relates to the technical field of display, and discloses a frame sealing structure and a display device. The frame sealing structure comprises a front shell, a light guide column and a packaging cover plate, a lap joint table is formed at the inner side of the front shell, and a first lap joint surface is formed on the surface of one side, facing the packaging cover plate, of the lapjoint table. The light guide column is arranged in a containing space formed by the front shell, a second lap joint surface is formed on the surface of one side, facing the packaging cover plate, ofthe light guide column, and the packaging cover plate is bonded with the first lap joint surface and the second lap joint surface through the optical cement. According to the frame sealing structure provided by the invention, the packaging cover plate and the first lap joint surface of the front shell are bonded by the optical cement, and the second lap joint surface of the light guide column andthe packaging cover plate are bonded by adopting the optical cement, so that the structure not only ensures the sealing performance of a frame, but also can reduce the bonding size between the packaging cover plate and the front shell, and accordingly the extreme size of the upper forehead of an electronic device can be reduced.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a frame sealing structure and a display device. Background technique [0002] In the current situation where the screen-to-body ratio of electronic devices is getting higher and higher, the size of the upper forehead has become a hot spot for competition among various manufacturers. At present, the sealing of the upper forehead optical distance sensing module of electronic equipment mainly relies on glue dispensing or foam glue sealing, and these two sealing methods require a certain effective width (the narrowest of glue dispensing is 0.60mm, and the narrowest of foam glue is 0.8mm). , the structure limits the limit size of the upper forehead, affecting the appearance of the product. Contents of the invention [0003] The present invention provides a frame sealing structure and a display device. The frame sealing structure is beneficial to reducing the limit size of the uppe...
