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 control structure, a backlight module and a display device, wherein the optical control structure includes a top plate, two side plates and a light control structure, wherein one end of the two side plates is respectively connected to the top plate, and the other end is respectively connected to the top plate. Installed on the reflective bottom plate to form a control space for covering the light source with the top plate, each side plate is provided with a first light-transmitting hole, and the light-adjusting structure is arranged on the inner wall of the top plate to increase the intensity of the light source. The quantity of light passing through the first light transmission hole to the outside of the control space after being reflected from the top plate. In the technical solution provided by the present invention, a dimming structure is provided on the inner side wall of the top plate to enhance the effect of light reflection or change the transmission direction of part of the light, so that the light from the light source is reflected from the top plate and passes through the first light transmission hole The number of lights passing through the control space improves the uniformity of light distribution and improves the display quality.

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...
