Embodiment Construction

[0040] The backlight module of the present invention mainly includes:

[0041] A frame body, which is a frame-shaped structure, has a vertical portion and a horizontal portion, and has a concave portion (or convex portion) in the vertical portion;

[0042] a light source is arranged inside the frame;

[0043] A reflection sheet is arranged on the lower side of the light source, has a vertical portion and a horizontal portion, and has a convex portion (or concave portion) on the vertical portion, and the convex portion and the concave portion are combined to fix the reflection sheet.

[0044] The above-mentioned concave part can be a fitting hole or a fitting groove, and the above-mentioned convex part is a fitting block corresponding to the concave part or any edge of the reflecting sheet.

[0045] The above-mentioned light source may be a direct-type light source or an edge-type light source.

[0046] In order to better understand the implementation forms of the present inv...

Abstract

The invention discloses a backlight module of a displayer, which comprises a frame body with a plasticized frame structure, a light source arranged on the inner side of the frame body, a reflector plate arranged on the lower side of the light source on the inner side of the frame body, and a light guide plate arranged on the inner side of the frame body and positioned on the upper side of the reflector plate and the same horizontal position as the light source, wherein the thickness after the reflector plate is overlapped with the light guide plate is not more than that of the frame body; the reflector plate is an optical reflector plate made of a foam plastic material and has the thickness greater than 0.5mm; and the periphery of the reflector plate is combined with the frame body. The backlight module can save rear panels and reduce the weight of the module and the manufacturing cost.

Description

【Technical field】 [0001] The invention relates to a backlight module, in particular to a backlight module which can save the use of a backboard, reduce the weight of the module, and reduce the manufacturing cost. 【Background technique】 [0002] According to the location of the light source, there are front light and backlight, and the light emitting modules generally used in flat display devices such as LCD almost all use backlight. The basic components of a general backlight module include a light source, a reflector, a light guide plate, a diffuser, etc. After the above-mentioned components are assembled in a frame, a backplane provides a support for the backlight module to support the components. Form an integral structure, and then combine the backlight module with a printed circuit board, a driving circuit, etc. as required. [0003] In addition, the backlight module is divided into side-light backlight module and direct-light backlight module. The light source of the ...
