Embodiment Construction

[0018] Please also refer to Figure 1 to Figure 2 , which is a perspective view of a display device 100 in a preferred implementation manner. The display device 100 is roughly in the shape of a cuboid. In this embodiment, the display device 100 may be a liquid crystal display device.

[0019] The display device 100 includes a casing 10 , a display panel 20 for displaying images, and a backlight module 40 for providing backlight for the display panel 20 .

[0020] The housing 10 includes a front shell 11 and a rear shell 13 fixed to the front shell 11 . The front shell 11 and the rear shell 13 cooperate to form a receiving space. Wherein, the display panel 20 and the backlight module 40 are accommodated in the rear case 13 , and the backlight module 40 is disposed close to the rear case 13 . In this embodiment, the rear case 13 may further accommodate structures such as a glass cover and a touch module.

[0021] see image 3 , the backlight module 40 includes a plurality ...

Abstract

The invention discloses a display device. The display device comprises a shell body and a backlight module arranged in the shell body. The backlight module comprises at least one light bar and a backboard. The backboard comprises a base board and at least one positioning mechanism. The positioning mechanisms are formed on the base board and used for positioning the position of the light bars on the backboard. Each positioning mechanism comprises two first limiting parts, a plurality of second limiting parts and a plurality of positioning columns; and the multiple second limiting parts and the multiple positioning columns are alternately arranged between the two first limiting parts. The first limiting parts, the second limiting parts and the positioning columns limit the light bars from the different directions so that the situation that the light bars move relative to the base board and move relative to the backboard can be prevented. The invention further provides the backlight module.

Description

technical field [0001] The invention relates to a display device and a backlight module. Background technique [0002] Existing display devices usually have a light bar structure for emitting light. In the prior art, the positioning method of the light bar is usually to cooperate with the plastic structure disposed on the bottom plate by screws. The above positioning methods all need to add other components on the bottom plate and the light bar, which increases the production cost. In the process of locking or dismounting by means of screw locking, multiple locking or dismounting operations are required, which increases the complexity of assembling the display device and reduces production efficiency. Contents of the invention [0003] In view of this, it is necessary to provide a display device that improves production efficiency. [0004] It is also necessary to provide a backlight module that improves production efficiency. [0005] A display device includes a casin...
