Thin type backlight module

Abstract

The invention discloses a thin back light module, comprising at least a light guiding plate, at least a light source and a display panel; the surface of the light guiding plate is provided with a concavo-convex light guiding diffusion structure; furthermore, the concavo-convex light guiding diffusion structure is covered by a reflection metal layer; the exposed surface of the reflection metal layer is covered by an anti-oxidant film; therefore, the concavo-convex light guiding diffusion structure of the light guiding plate is matched with the reflection metal layer so as to guide the light source to diffuse and refract towards the display panel; furthermore, the thickness of the existing back light module design is effectively reduced.

Description

technical field [0001] The invention relates to a backlight module. Background technique [0002] General liquid crystal panels (LCD) almost all use backlight modules to generate light sources to achieve display effects, and backlight modules mainly provide uniform and high-brightness light sources for LCD panels. The basic principle of backlight modules is to use commonly used point or line light sources through Concise and effective guide refraction into surface light source products with high brightness and uniform illuminance. With the improvement of liquid crystal display manufacturing technology in recent years, under the trend of small size and low price, backlight modules are considering light weight, thinner, and lower power consumption. In order to maintain the competitiveness in the future market, to further develop and design new backlight module technology is the direction and important topic that R&D personnel are striving for in order to meet the market requir...

AI Technical Summary

Problems solved by technology

[0008] Firstly, because the reflection plate 10 must guide light from other directions into the optical light guide plate 11, and the reflection plate 10 and the optical light guide plate 11 are independently and separately assembled in the backlight module, the aforementioned conventional methods are now The simplest design in the technology, so it is still difficult to produce products with a simpler and thinner design than this conventional technology;

[0009] Second, since the reflection plate 10 and the optical light guide plate 11 are independently manufactured and assembled separately, the production process cannot be simplified, and the labor costs of multi-layer assembly, cladding and layer-by-layer manufacturing are all high
