Problems solved by technology

However, in the prior art, since the light-emitting surface of the diffuser plate is generally flat, the impact effect of the viewing angle is poor when the light source is diffused through the light-emitting surface of the diffuser plate.

Embodiment 1

[0026] In this embodiment, a frameless rubber-iron integrated backlight module that can improve the impact effect of viewing angles, such as figure 1 As shown, it includes a back frame 1, a backlight 2 arranged in the back frame 1 and composed of a plurality of light emitting sources, a light guide plate 3 arranged on one side of the backlight 2, and a diffusion plate 4 arranged on the light guide plate 3 The diffuser plate 4 includes a light incident surface 41 and a light output surface 42, and the light output surface 42 of the diffuser plate 4 is formed by splicing several triangles 401 arranged in sequence. Since the light emitting surface 42 of the diffuser plate 4 is spliced ​​by several triangles 401 arranged in sequence, the light source is scattered multiple times at several triangular surfaces, which can increase the area of ​​the light emitting surface, thereby greatly enhancing the scattering effect when emitting light. Furthermore, when the light source is scatte...

Embodiment 2

[0031] Embodiment 2 of a frameless rubber-iron integrated backlight module of the present invention that can improve the impact effect of viewing angles. The difference between this embodiment and Embodiment 1 is that in this embodiment, the width of the base of the triangle 401 is Set to 3mm. The height of the triangle 401 is set to 2 mm. The light-emitting surface 42 formed by splicing triangles 401 of this size can make the light source scatter multiple times on several triangular surfaces, increase the area of ​​the light-emitting surface, and then greatly enhance the scattering effect when the light is emitted, so that the light source passes through the diffusion plate. 4. When the light-emitting surface is scattered and diffused, the viewing angle impact effect is good. In this embodiment, the diffusion plate 4 is a diffusion plate 4 made of PET plastic, which facilitates multiple scattering of the light source at several triangular surfaces, increases the area of ​​th...

Embodiment 3

[0033] Embodiment 3 of a frameless rubber-iron integrated backlight module of the present invention that can improve the impact effect of viewing angles. The difference between this embodiment and Embodiment 1 is that in this embodiment, the width of the base of the triangle 401 is Set to 0.5mm. The height of the triangle 401 is set to 0.5 mm. The light-emitting surface 42 formed by splicing triangles 401 of this size can make the light source scatter multiple times on several triangular surfaces, increase the area of ​​the light-emitting surface, and then greatly enhance the scattering effect when the light is emitted, so that the light source passes through the diffusion plate. 4. When the light-emitting surface is scattered and diffused, the viewing angle impact effect is good. In this embodiment, the diffusion plate 4 is a diffusion plate 4 made of HDPE plastic, which facilitates multiple scattering of the light source at several triangular surfaces, increases the area of...

Abstract

The invention relates to the technical field of backlight modules, in particular to a frameless glue-iron integration backlight module improving the visual impact effect. The frameless glue-iron integration backlight module improving the visual impact effect structurally comprises a back frame, a backlight source arranged in the back frame and composed of a plurality of light sources in an arranged mode, a light guiding plate arranged on one side of the backlight source and a diffusion plate arranged on the light guiding plate; the diffusion plate comprises an incident light surface and a light outgoing surface, and the light outgoing surface of the diffusion plate is formed in the mode that a plurality of sequentially-arranged triangles are spliced. As the light outgoing surface of the diffusion plate is formed in the mode that the multiple sequentially-arranged triangles are spliced, the light source is scattered many times at the multiple triangle faces, the area of the light outgoing surface can be increased, the scattering effect during light outgoing can be thus greatly enhanced, and the visual impact effect is good when the light source is scattered and diffused through thelight outgoing surface of the diffusion plate.

Description

technical field [0001] The invention relates to the technical field of backlight modules, in particular to a frameless rubber-iron integrated backlight module capable of improving the impact effect of viewing angles. Background technique [0002] According to different incidence modes of the light source, the backlight module can be divided into a direct-type backlight module and an edge-type backlight module. Among them, the side-type backlight module is to install the backlight LED strip on the edge of the back panel behind the liquid crystal panel. The light emitted by the LED strip enters the light guide plate from the light incident surface on one side of the light guide plate and is reflected and diffused. It emits from the light-emitting surface of the light guide plate, and then passes through the optical film group to form a surface light source and provide it to the liquid crystal panel. [0003] In the backlight module in the prior art, the light source is genera...
