Detailed ways

The present invention will be further clarified below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

Example: Referring to FIGS. 1-4, a narrow-frame liquid crystal display module includes an outer casing 100 and a display panel main body 200 clipped into the outer casing 100. The outer casing 100 is used to connect with a device casing 300 (such as the plastic shell) with embedded fit;

Referring to FIG. 2 , the outer casing 100 has a rectangular shape, and a mounting groove 101 for placing the display panel body 200 is recessed in the middle of the outer casing 100 . The distance between 111 and the inner side wall of the installation groove 101 gradually decreases from bottom to top;

The device casing 300 is provided with a placement groove that is snap-fitted with the outer casing 100. The inner wall of the placement groove is an inner concave surface 301 that press-fits against the mating surface 111 of the outer casing 100. The inner wall of the installation groove 101 is connected to the main body of the display panel. There is a filling gap between the 200, and the filling gap is filled with an elastic glue layer, and the elastic glue layer is a silicone layer, which can play an elastic buffering role;

Since the outer side walls of the outer casing 100 of the display module are all inclined mating surfaces 111 , the distance between the mating surfaces 111 and the inner side walls of the installation groove 101 gradually decreases from bottom to top; , can be embedded in the concave surface 301 of the device casing 300, that is, the thickness of the top of the outer casing 100 is set to be small, and the overall thickness increased when the device casing 300 is snap-fitted, which is beneficial to the main body of the display panel. 200 Overall edge thickness reduction.

In order to improve the stability of the glue layer in the filling gap and prevent it from degumming during long-term use, the inner side wall of the installation groove 101 is recessed inward to form a filling groove 112, and the top of the filling groove 112 has a horizontally extending rib 113 , a filling gap is formed between the filling groove 112 and the outer wall surface of the display panel main body 200 , and the top of the filled glue layer can be blocked and limited by the baffle 113 after the filled glue layer is cured to prevent it from coming off.

A vertically arranged extension edge is formed between the inner side wall of the installation slot 101 and the retaining edge 113 , and a plurality of arc-shaped limit slots 115 are formed on the extension edge along the vertical direction, and the multiple arc-shaped limit slots 115 are parallel and spaced apart. When the glue is filled, part of the glue can overflow upwards at the position of the arc-shaped limit groove 115, and the concave part of the arc-shaped limit groove 115 is beneficial to retain the glue and improve the coverage of the glue.
