Embodiment Construction

[0037] The invention provides a backlight module, in which a carrying part is set in a metal back frame to carry an optical sheet. Therefore, the plastic frame can be omitted to reduce the cost, and the assembly steps can also be reduced to simplify the assembly process. A group of preferred embodiments are given below as a detailed description, but the words and illustrations are only for illustration, and the intended protection scope of the present invention should be defined by the claims, and the words and illustrations in the description do not protect the intended protection of the present invention. The scope is narrowed.

[0038] FIG. 2 is an exploded view of a liquid crystal display according to a preferred embodiment of the present invention. Referring to FIG. 2 , the liquid crystal display 200 at least includes a display panel 216 and a backlight module 220 . The backlight module 220 is located at the back of the display panel 216 for providing sufficient light t...

Abstract

The present invention provides a backlight module, having a metal back frame which is capable of bearing the optical sheet. The backlight module includes a metal back frame, an optical source and an optical sheet. The light source is placed in the bearing part extended from the metal back frame for uniform the light source.

Description

technical field [0001] The invention relates to a liquid crystal display, and in particular to a backlight module of a liquid crystal display. Background technique [0002] Due to the liquid crystal display (Liquid Crystal Display, LCD) has the characteristics of light and thin volume, space saving, low power consumption and low radiation pollution, etc., it has gradually replaced the traditional cathode ray tube (Cathode Ray Tube, CRT) display in recent years and has become a new generation of Standard equipment for computers. [0003] Please refer to FIG. 1A , which shows an exploded view of a conventional liquid crystal display. In FIG. 1A , the liquid crystal display 100 at least includes a front case 111 , a display panel 116 , a backlight module 140 , a partition 122 , a circuit board 123 and a rear case 124 . The circuit board 123 is used to drive the backlight module 140 and the display panel 116 . The backlight module 140 is located at the back of the display pan...
