[0035] In existing display screen structures, glue is typically dispensed around the mounting frame to achieve adhesion between the glass panel and the frame. During this process, factors such as the fluidity and uneven distribution of the glue can easily lead to glue overflow around the mounting frame. This overflow not only affects the display's appearance but can also create a short circuit risk to the display's internal circuitry.

[0036] The utility model provides an LCD display screen.

[0037] See also Figures 1 to 3 In one embodiment of the present invention, the LCD display screen 100 includes:

[0041] The glass plate 4 is disposed on a side of the display screen body 2 facing away from the back plate 3 . The glass plate 4 is bonded to the interior of the mounting frame 1 by filling the first embedding groove 11 with adhesive.

[0042] The technical solution of the present invention is to provide a first embedding groove 11 on the periphery of the mounting frame 1. The first embedding groove 11 is a groove recessed from the surface of the mounting frame 1. By filling the groove with an adhesive, such as by dispensing glue, the adhesive can be a silicone or epoxy resin adhesive, etc., so that the glass plate 4 is firmly fixed to the interior of the mounting frame 1, achieving a close connection with the mounting frame 1, reducing displacement caused by vibration, and improving the shock resistance of the display screen. In addition, the provision of the glass plate 4 and the back plate 3 can provide additional protection for the front and rear of the display screen body 2, respectively, to prevent damage to the display screen caused by external physical impact. The provision of the first embedding groove 11 effectively avoids the problem of excessive filling of adhesive and overflow affecting the aesthetics of the mounting frame 1.

[0043] Specifically, the configuration of the first embedding groove 11 is not specifically limited. For example, it can be a continuous groove extending around the perimeter of the mounting frame 1, or it can be a plurality of intermittent grooves spaced at regular intervals on the mounting frame 1. Optionally, the multiple intermittent grooves are evenly spaced to ensure that every portion of the glass plate 4 can be bonded and secured to the mounting frame 1. The first embedding groove 11 can be stepped, with one or more steps provided at the edge of the mounting frame 1. Once the glass plate 4 is embedded, the steps provide additional support and securement. Furthermore, the steps effectively prevent excess adhesive from overflowing onto the periphery of the mounting frame 1.
