Embodiment Construction

[0018] Below in conjunction with the best embodiment shown in the accompanying drawings, it will be further described in detail.

[0019] see figure 2 , the embodiment of the liquid crystal display device and its backlight module of the present invention roughly includes: a liquid crystal panel 1 , a back plate 2 , a light source 3 and a diffusion sheet 4 . in,

[0020] The upper surface of the backplane 2 is an uneven surface 21 . The uneven surface 21 is formed by a plurality of protrusions 211 and depressions 212 formed on the upper surface of the back plate 2 . Wherein, the arrangement of the plurality of protruding portions 211 and the recessed portions 212 may preferably be arranged side by side in a corrugated manner by a plurality of strip-shaped protruding portions 211 and strip-shaped recessed portions 212, or may be a plurality of The dot-shaped protrusions 211 and the dot-shaped depressions 212 are arranged in an array.

[0021] The light source 3 is arranged ...

Abstract

The invention discloses a liquid crystal display device and a backlight module thereof. The backlight module provided by the invention comprises a back board, the upper surface of the back board is an uneven surface, and the uneven surface is composed of multiple projecting parts and sunken parts formed on the upper surface of the back board; or, the uneven surface is composed of a fogging surface formed on the upper surface of the back board, and a light emitting source matched with the back board is positioned above the back board and emits light towards the uneven surface. The liquid crystal display device provided by the invention can be used for better solving the problem of nonuniform intensity distribution and is easy to manufacture.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to the structure of a backlight module in the liquid crystal display device. Background technique [0002] A liquid crystal display device uses liquid crystals to provide image display, and is usually composed of a liquid crystal panel, a backlight module, related digital circuits, and a power supply. Classified by the position of the lamp tube, the backlight module can be mainly divided into three categories: 1. Side-light structure, the light source is located on the side of the light guide plate; 2. Direct-down structure, the light is emitted from the spontaneous light source and passes through the reflector After reflection, it is evenly dispersed upward by the diffusion plate and then emitted from the front; 3. Hollow structure, using a hot cathode tube as a light source, using air as a light medium, and the light is adjusted and reflected by the prism sheet and the reflector ...
