Embodiment 1

[0046] figure 1 It is a schematic structural diagram of the backlight module in Embodiment 1 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 board 130 and a support bar 140 .

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

Embodiment 2

[0074] image 3 It is a schematic structural diagram of the backlight module in Embodiment 2 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 between the bottom of the placement groove 114 and the side wall of the placement groove 114 is different. In the second embodiment, the bottom of the placement groove 114 is flexibly connected to the side walls of the placement groove 114 , while in the first embodiment, the bottom of the placement groove 114 and the side walls of the placement groove 114 are integrally formed.

[0075] It should be noted that the groove bottom of the placement groove 114 is movably connected with the groove side wall of the placement groove 114, that is to say, the groove bottom of the placement groove 114 can slide in the groove side wall of the placement groove 114, away from or close to the optical film 120. Make the optical di...

Embodiment 3

[0080] Figure 4 It is a schematic structural diagram of the backlight module in Embodiment 3 of the present application, see Figure 1 to Figure 4 As shown, the main difference between the third embodiment and the first and second embodiments lies in the way of connecting 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 can be connected by a screw structure. For example, the screw structure includes a screw 133 and a threaded hole provided on the light source substrate 131. The threaded hole is located at the edge of the light source substrate 131. The screw 133 is screwed into the threaded hole on the light source substrate 131 through the groove bottom of the placement groove 114 to connect the light source. substrate 131 and backplane 110 .

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

Abstract

The invention belongs to the field of display, and particularly relates to a backlight module and a display device.The backlight module comprises a back plate, an optical film, a light source plate and a supporting strip, the light source plate and the optical film are both installed on the back plate, and the optical film is located on the light emitting side of the light source plate; the supporting strip is located on the side, away from the optical film, of the light source plate, the supporting strip is provided with a first supporting face and a second supporting face, the first supporting face makes contact with the local area of the back plate, and the second supporting face makes contact with the local area of the light source plate; the thickness or the position of the supporting strip in the light emitting direction can be adjusted, so that the optical distance between the light source plate and the optical film can be adjusted. The light source plate is supported through the supporting strips, the optical film is supported through the back plate, a supporting column between the optical film and the light source plate can be omitted, and therefore the situation that the supporting column shields light and influences the optical grade is avoided.

Description

technical field [0001] The application belongs to the display field, 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-lit backlight module are supported by a support column, and the optical distance (Optical Distance) between the light bar and the diffuser can be adjusted by adjusting the height of the support column. The support column is set 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. Contents 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 diffusion sheet and the light bar from blocking light. [0004] In order to achieve the above purpose, the present application provides a backlight module, including a backplane, an optical film and a light source...
