display device

technical field

The invention relates to a display device, in particular to a display device for improving assembly reliability.

Background technique

Liquid Crystal Display (LCD) has the advantages of high image quality, small size, light weight, low voltage drive and low power consumption, so it has been widely used in portable TVs, mobile phones, camcorders, notebook computers , desktop monitors and televisions and other consumer electronics products.

Taking a TV as an example, the TV includes a display module and a housing. The display module generally includes an iron frame and a display panel. The iron frame covers the display panel and exposes the display area of the display panel. The outer shell covers the iron frame of the display module and exposes the display area of the display panel. Wherein, the casing covers the iron frame to prevent the iron frame from being exposed and affecting the appearance of the TV.

However, as the size of TVs is getting bigger and bigger nowadays, the weight of the display module inside the TV is getting heavier and heavier. Therefore, after the casing is assembled with the iron frame, if the material strength of the casing cannot bear the weight of the display module, the casing may be damaged. Deformation due to extrusion of the display module. The deformation of the shell may expose the iron frame, which will affect the appearance of the TV.

FIG. 5 is a cross-sectional view of the assembled structure of the display module 100 , the assembly part 200 and the rear case 400 . FIG. 6 is a cross-sectional view of the assembled structure of the display module 100 , the assembly part 200 , the front case 300 and the rear case 400 . Referring to FIG. 6 , it is worth noting that the distance between the second resisting portion 330 and the second plate 320 is smaller than the distance between the second locking portion 340 and the second plate 320 . The distance from the third plate 350 to the first plate 310 is greater than the width of the second side plate 112 .

Next, in order to continue describing the assembly process of the display device 10 , please continue to refer to FIGS. 5 and 6 , which are also schematic diagrams of the assembly sequence of FIG. 1 . Firstly, as shown in FIG. 5 , the first fixing part 410 of the rear case 400 and the second fixing part 230 of the assembly part 200 are pierced by the locking member 500 to lock the rear case 400 to the display module 100 . Next, as shown in FIG. 6 , the front case 300 is assembled on the back panel 113 of the display module 100 . Specifically, the first buckle part 114 is buckled to the second buckle part 340, and the resisting section 222 of the first resisting part 220 is inserted into the groove 331 of the second resisting part 330, so that the first The plate 310 covers the first side plate 111, the second plate 320 covers the second side plate 112, the opening 321 reveals the display area 104, and the second side plate 112 is between the first plate 310 and the third plate 350 , and the display module 100 is located between the rear case 400 and the second panel 320 . However, the assembling sequence described in this embodiment is not intended to limit the present invention. In other embodiments, the front casing 300 may be assembled first, and then the rear casing 400 may be assembled.

Please refer to FIG. 7 . FIG. 7 is a schematic cross-sectional view along line BB in FIG. 1 . With the above structural configuration, when the front housing 300 is squeezed by the display module 100 or deformed due to assembly tolerances among the components of the display device 10 , the second plate 320 is far away from the second buckle portion 340 And it is easier to be deformed by being extruded by the deformation force F1 of valgus. However, because the second abutting portion 330 of this embodiment is closer to the second plate 320 than the second buckle portion 340, when the first abutting surface 223 of the first abutting portion 220 abuts against the second abutting portion 330 When a reaction force F2 against the deformation force F1 is generated by the second abutting surface 334 , the reaction force F2 and the deformation force F1 will cancel each other to reduce the degree of deformation of the second plate 320 . Thereby, the assembly reliability between the front case 300 and the outer frame 110 can be improved, and the outer frame 110 inside the display device 10 can be prevented from being exposed to affect the appearance of the display device 10 .

Next, please continue to refer to FIG. 8 , which is a schematic cross-sectional view of a display device according to a second embodiment of the present invention. This embodiment is similar to the above embodiment in FIG. 1 , so only the differences will be described.

In order to further improve the assembly reliability between the front case 300 and the outer frame 110 of the display module 100 , the first resisting portion 220 further includes a rib 224 . The convex rib 224 is located on the side of the first abutting surface 223 close to the second plate 320 , so that when the front case 300 is assembled on the outer frame 110 , the convex rib 224 will abut against the abutting section 333 close to the second plate 320 One side improves the assembly reliability between the front case 300 and the outer frame 110 .

According to the above display device disclosed in the present invention, since the assembly is additionally provided with a first abutting portion, and the first abutting portion is closer to the second plate than the first buckle portion, the first abutting portion abuts against the second plate. The second abutting portion can provide a reaction force against the deformation force, so as to reduce the degree of deformation of the second plate. In this way, the assembly reliability between the front case and the outer frame can be improved, thereby preventing the inner outer frame of the display device from being exposed and affecting the appearance of the display device.

It should be noted that although in the embodiment of the present invention, both the first abutting portion 220 and the second abutting portion 330 have inner surfaces parallel to the side surface 103 of the display module 100 , and the first abutting portion 220 The inner surfaces of the second resisting portion 330 are opposed to each other, but the present invention is not limited to utilizing the structure with parallel inner surfaces to achieve the function of mutual resistance between the components. In other embodiments, two arc-shaped, hook-shaped or other abutting parts that can make the elements abut against each other along the direction perpendicular to the side surface 103 can also be used.
