Example one
The utility model provides an embodiment of a display device, comprising:
a back plate 100 formed by integral press molding, the back plate 100 having an insertion cavity 120 with an opening 110 formed at one side;
the back plate 100 is a rigid member formed by stamping integrally, which ensures sufficient strength, and the insertion cavity 120 may be U-shaped or V-shaped, and is not limited herein.
And a display panel 200 bonded to the back plate 100, wherein the display panel 200 is a liquid crystal display.
An optical film assembly 300 slidably inserted into the insertion cavity 120 from the opening 110;
in some embodiments of the present application, the optical film assembly 300 includes a film 310 and a diffusion plate 320, which are disposed in sequence from top to bottom, that is, the film 310 is disposed above the diffusion plate 320 and fixed to the diffusion plate 320 by gluing.
And a stopper 400 disposed on a wall of the insertion cavity 120 and facing the optical film assembly 300, wherein a protrusion 410 extending toward the optical film assembly 300 and pressing and positioning the optical film assembly 300 is formed on the stopper 400, and the protrusion 410 has elasticity.
The display device provided in this embodiment has a simple overall structure, and when the display device is set, the rear panel 100 is formed by integral press molding, which simplifies the manufacturing process.
Meanwhile, the back plate 100 is directly connected with the display panel 200, so that a middle frame structure is omitted, the material consumption of the whole display equipment is greatly reduced, and the production and manufacturing cost of the whole display equipment is reduced.
When the installation is carried out, the display panel 200 is directly bonded on the backboard 100, the optical diaphragm assembly 300 is directly assembled on the backboard 100 along the sliding assembly of the opening 110 on one side of the backboard 100 in the direct sliding drawing mode, the assembly is simpler and more convenient, and compared with the mode of independently assembling and installing all the components in the transmission display equipment, the assembly is simpler, more convenient and faster.
Because the backplate 100 in this embodiment is formed by integral punching, a plug-in cavity 120 is directly punched inside, and the optical film assembly 300 is drawn and pulled in a drawer type, and the backplate 100 cannot be provided with a corresponding limit structure, the thickness of the optical film assembly 300 is much smaller than the height of the plug-in cavity 120, as shown in fig. 1, so that the optical film assembly 300 cannot be fixed by a double-sided adhesive tape, and the problem of infirm assembly and fixation of the optical film assembly 300 is easily caused.
Specifically, in the present embodiment, to solve the problem, a limiting member 400 is provided, and a protrusion 410 is provided on the limiting member 400, so that the protrusion is elastic and perpendicular to the sliding direction of the optical film assembly 300.
In this embodiment, the corresponding limiting member 400 on the wall of the insertion cavity 120 effectively limits and fixes the optical film assembly 300 on the premise that the limiting member 400 ensures the assembly gap of the optical film assembly 300, so as to achieve the effect of replacing double-sided adhesive tape fixation, ensure the firm fixation of the optical film assembly 300, and avoid the occurrence of the situation that the optical film assembly 300 moves along the direction perpendicular to the display panel 200 and collides with the display panel 200 to cause the downward partial abrasion of the display panel 200.
When the optical film 310 assembly is assembled in the insertion cavity 120 in a sliding manner along the opening 110 by an external force, an acting force is applied to the protruding portion 410, the protruding portion 410 is slightly deformed by extrusion, the optical film assembly 300 is normally installed in the sliding manner through deformation of the protruding portion 410, and after the external acting force is eliminated after the optical film assembly is assembled in place in the sliding manner, the protruding portion 410 is restored to be deformed and applies an extrusion acting force to the optical film assembly 300 so as to be matched with the side wall of the insertion cavity 120 to clamp and fix the optical film assembly 300.
Through the limiting member 400 and the protruding portion 410 located above the limiting member, the firmness of locking and fixing between the integrally formed stamping backboard 100 and the optical film assembly 300 is ensured, and the situation that the display panel 200 is worn downward due to the fact that the optical film assembly 300 is not fixed firmly and moves towards the display panel 200 is effectively avoided.
In some embodiments of the present application: the limiting member 400 includes a body 420 and a plurality of protrusions 410 disposed on the body 420, and the plurality of protrusions 410 are disposed along a length direction of the body 420.
