Embodiment Construction

[0023] The present invention provides a backlight module and a display device. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] see figure 2 , the present invention provides a backlight module, including a Mini LED lamp board 60, and a light guide body 70 arranged above the Mini LED lamp board, the cross section of the light guide body is an inverted trapezoid, and the side of the light guide body A microstructure array 80 is provided on the wall and / or the bottom surface of the light guide body, and a reflective film 90 is pasted on the side wall surface of the light guide body. Specifically, the purpose of the technical solution of the present invention is to provide a Mini LED backlight module...

Abstract

The invention provides a backlight module and display equipment, and the backlight module is characterized by comprising a Mini LED light board and a light guide body disposed above the Mini LED lightboard, wherein the cross section of the light guide body is an inverted trapezoid, microstructure arrays are disposed on the side wall and / or the bottom surface of the light guide body, and a reflective film is pasted on the side wall surface of the light guide body. Since the backlight module provided by the invention uses the light guide body with an inverted trapezoidal cross section for lightguidance, the inverted trapezoidal light guide body can convert the point light sources emitted by the Mini LED into a surface light source. The bottom surface and / or side wall of the light guide body is arranged with microstructure arrays, which can can enhance the light scattering inside the light guide body such that the light inside the light guide body is more emitted from the top surface. The backlight assembly provided by the invention can also form a whole large-sized light emitting surface by splicing a plurality of light guide bodies, having more uniform light output and better backlight effect.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a backlight module and a display device. Background technique [0002] Mini LED chip is a kind of LED chip with a chip size of about 100μm×100μm. It has the advantages of high color saturation, local dimming, high brightness, and energy saving. It can be applied to backlight displays and has become a recent research hotspot. [0003] see figure 1 , an existing Mini LED backlight display structure, including a backplane frame 10, a plurality of Mini LED light panels 20 are arranged side by side inside the backplane frame, and a diffuser plate 40 is arranged on the top of the Mini LED light panel through a support frame 30 And the diaphragm 50, the existing above-mentioned Mini LED backlight display structure has the following defects: (1) there are splicing gaps between the Mini LED lamp panels, and grid patterns are prone to appear in the visual effect; (2) due to the sm...
