Embodiment 1

[0046] figure 1 is a schematic structural diagram of the backlight module in the first embodiment of the present application, see figure 1 As shown, the backlight module in this embodiment includes: a backplane 110 , an optical film 120 , a light source plate 130 and a support bar 140 .

[0047] The light source plate 130 and the optical film 120 are both mounted on the back plate 110 , and the optical film 120 is located on the light-emitting side of the light source plate 130 . The support bar 140 is in the shape of a long strip, and its width and thickness are both smaller than its length, and the thickness direction and the light exit direction are the same direction. The support bar 140 is located on the side of the light source board 130 away from the optical film 120 , the support bar 140 has a first support surface and a second support surface, the second support surface is a support surface in the thickness direction of the support bar 140 , and the first support sur...

Embodiment 2

[0074] image 3 is a schematic structural diagram of the backlight module in the second embodiment of the present application, see Figure 1 to Figure 3 As shown, the main difference between the second embodiment and the first embodiment is that the connection structure of the groove bottom of the placing groove 114 and the groove side wall of the placing groove 114 is different. In the second embodiment, the slot bottom of the placement slot 114 and the slot side wall of the placement slot 114 are movably connected, while in the first embodiment, the slot bottom of the placement slot 114 and the slot side wall of the placement slot 114 are integrally formed.

[0075] It should be noted that the slot bottom of the placement slot 114 is movably connected to the slot side wall of the placement slot 114, that is, the slot bottom of the placement slot 114 can slide in the slot side wall of the placement slot 114, away from or close to the optical film Step 120, make the optical d...

Embodiment 3

[0080] Figure 4 is a schematic structural diagram of the backlight module in the third embodiment of the present application, see Figure 1 to Figure 4 As shown, the main difference between Embodiment 3 and Embodiment 1 and Embodiment 2 lies in the connection method between the light source substrate 131 and the groove bottom of the placement groove 114 .

[0081] In the third embodiment, the light source substrate 131 and the groove bottom of the placement groove 114 may be connected by a screw structure. For example, the threaded structure includes screws 133 and threaded holes provided on the light source substrate 131, the threaded holes are located at the edge of the light source substrate 131, and the screws 133 pass through the bottom of the slot 114 and screw into the threaded holes on the light source substrate 131 to connect the light source The substrate 131 and the backplane 110 .

[0082] The light source substrate 131 and the back plate 110 are connected by a ...

Abstract

This application belongs to the field of display, and specifically relates to a backlight module and a display device. The backlight module includes a backplane, an optical film, a light source board and a support bar. Both the light source board and the optical film are installed on the back board, and the optical film is located on the light emitting side of the light source board, the support bar is located on the side of the light source board away from the optical film, and the support bar has a first support surface and a second support surface , the first support surface is in contact with a local area of ​​the backplane, the second support surface is in contact with a local area of ​​the light source board, the thickness of the support bar in the light emitting direction or in the light emitting direction The position of can be adjusted, so that the optical distance between the light source board and the optical film can be adjusted. The light source board is supported by the support bar, and the optical film is supported by the back plate, which can save the support column between the optical film and the light source plate, so as to prevent the support column from blocking the light and affecting the optical quality.

Description

technical field [0001] The present application belongs to the field of display, and in particular relates to a backlight module and a display device. Background technique [0002] At present, the diffuser and the light bar of the direct-type backlight module are supported by a support column, and the optical distance between the light bar and the diffuser can be adjusted by adjusting the height of the support column. The support column is arranged between the diffuser and the light bar, which is easy to block the light and form the shadow of the support column, which affects the optical taste. SUMMARY OF THE INVENTION [0003] The purpose of the present application is to provide a backlight module and a display device to prevent the support column between the diffuser and the light bar from blocking light. [0004] In order to achieve the above purpose, the present application provides a backlight module, comprising a backplane, an optical film and a light source board, w...
