Embodiment Construction

[0025] In order to make the above and other objects, features, and advantages of the present invention more clearly understood, a preferred embodiment is specifically cited below, and in conjunction with the accompanying drawings, the detailed description is as follows:

[0026] figure 2 It is a side view of a backlight module 20 in a preferred embodiment of the present invention. The backlight module 20 of the present invention includes a front frame 21, a set of optical films 22, a light guide plate 23, at least one lamp assembly 24 and a reflective The metal back frame 25 of inner surface. Wherein, the optical film 22 is disposed on the light guide plate 23 , and the optical film 22 and the light guide plate 23 are sequentially disposed in the metal back frame 25 . In addition, the lamp assembly 24 is located beside the light guide plate 23 . The appearance of the metal back frame 25 is similar to a box without a cover.

Abstract

The invention relates to a backlight module, including a metal backframe, a light-conducting plate and at least a lamp tube assembly. The light-conducting plate and lamp tube assembly are placed in the interior of said metal backframe, and the lame tube assembly is positioned by light-conducting plate. Said metal backframe has a reflecting surface faced with light-conducting plate. When the light sent by lamp tube assembly is come into the light-conducting plate, the reflecting surface can be used for reflecting the light leaked form light-conducting plate back into the light-conducting plate, and said reflecting surface is a surface undergone the process of anode bright silver treatment.

Description

Technical field: [0001] The invention relates to a backlight module, in particular to a backlight module which does not need a reflection sheet. Background technique: [0002] The backlight module (Back Light Module) is the key zero assembly of the liquid crystal display panel (LCD Panel). Since the liquid crystal itself does not emit light, the function of the backlight module is to provide a light source with sufficient brightness and uniform distribution, so that the liquid crystal display panel can display images normally. As liquid crystal display panels have been widely used in many electronic products with development potential, such as monitors, notebook computers, etc., the demand for backlight modules and related parts and assemblies naturally continues to grow. Wherein, the reflective sheet in the backlight module reflects the light leaked from the light guide plate (Light Guide Plate) back into the light guide plate, so as to increase the brightness of the liqui...
