Problems solved by technology

[0005] Since the light source reflector 15 is made by plastic injection process, the cost of the mold is relatively high, which makes the cost of the light source reflector 15 relatively high.
In addition, the material of the light source reflector 15 is plastic, and since the reflectivity of the plastic is low, the reflectivity of the light source reflector 15 is low, which may easily cause dark parts to appear on both sides of the backlight module 10.

Abstract

The invention relates to a backlight module comprising a back plate, a reflection structure and a light source, wherein one side of the back plate is provided with a U-shaped accommodating part; the U-shaped accommodating part comprises a bottom, a side part which is connected with the bottom and forms an angle with the bottom and a top connected with the side part and opposite to the bottom. The reflection structure is configured on the bottom and the top and forms an accommodating space together with the side of the back plate. The light source is configured on the back light and extends into the accommodating space.

Description

【Technical field】 [0001] The present invention relates to a backlight module, and in particular to a direct type backlight module. 【Background technique】 [0002] With the development of the industry, products such as mobile phones, digital cameras, digital video cameras, notebook computers, desktop computers, and televisions are all oriented towards more convenient and versatile products. Development in a functional and aesthetic direction. However, when using the above-mentioned products, the display screen is an indispensable human-machine communication interface, and the display screen of the above-mentioned product will bring more convenience to the user's operation. Currently, a liquid crystal display is a common display screen. However, since the liquid crystal display itself does not have the function of emitting light, a backlight module needs to be provided in the liquid crystal display as a light source to achieve the display function. [0003] figure 1 It is a...
