Problems solved by technology

[0002] The optical control structure is widely used in the backlight module. The light emitted by the light source is guided by the optical control structure and the transmission direction or distribution mode of the light emitted by the light source is adjusted, and then exits the backlight module. However, although the backlight module has The optical control structure is used to adjust the transmission direction or distribution of light, but there will still be some uneven distribution of light and dark. Therefore, how to make the backlight module emit light with uniform brightness has always been the goal of this field.

Abstract

The invention discloses an optical adjustment and control structure, a backlight module and a display device. The optical adjustment and control structure includes a top plate, two side plates and a light adjusting structure, one ends of the two side plates are correspondingly connected with the top plate, the other ends of the two side plates are correspondingly used for being installed on a reflection bottom plate to form an adjustment and control space with the top plate, wherein the adjustment and control space is used for covering a light source, first light transmission holes are formed in one side plate in a penetrating mode, and the light adjusting structure is arranged on the inner side wall of the top plate and used for increasing the number of light rays, reflected from the top plate and then passing through the first light transmission holes to penetrate out of the adjustment control space, of the light source. According to the technical scheme, the light adjusting structure is arranged on the inner side wall of the top plate, the effect of enhancing light ray reflection is achieved or the transmission direction of part of the light rays is changed, the number of the light rays, reflected from the top plate and then passing through the first light transmission holes to penetrate out of the adjustment control space, of the light source is increased, the uniformity of light distribution is improved, the display quality is also improved.

Description

technical field [0001] The invention relates to the technical field of flat panel displays, in particular to an optical control structure, a backlight module and a display device. Background technique [0002] The optical control structure is widely used in the backlight module. The light emitted by the light source is guided by the optical control structure and the transmission direction or distribution mode of the light emitted by the light source is adjusted, and then exits the backlight module. However, although the backlight module has The optical control structure is used to adjust the transmission direction or distribution of light, but there is still some uneven distribution of light and dark. Therefore, how to make the backlight module emit light with uniform brightness has always been the goal of this field. Contents of the invention [0003] The main purpose of the present invention is to provide an optical control structure, a backlight module and a display dev...
