Embodiment Construction

[0018] The following illustrates the backlight module provided by the present invention in combination with icons:

[0019] see figure 2 The backlight module provided by the present invention includes a flat cold cathode lamp 30 and a light guide plate 20. The light guide plate 20 can be flat or wedge-shaped, and its shape is not limited. It includes a light incident surface 21, A light-emitting surface 23 and a reflecting surface 22 opposite to the light-emitting surface, V-shaped grooves are formed on the reflecting surface 22 and the light-emitting surface 23; the cold cathode lamp 30 is located on the light-incident surface 21 side of the light guide plate 20, wherein the A nano-scale silicon dioxide particle layer 32 is formed on the surface of the lamp tube 31 of the cold cathode lamp 30 .

[0020] Wherein the cold cathode lamp 30 is designed to be flat so that it is close to a side light source, which is beneficial to improve the uniformity of the backlight source.

Abstract

The invention relates to a negative phototropic module which comprises a cold-cathode lamp and a light guiding plate, wherein the light guiding plate comprises a light incidence side, a light exit side and a reflecting side which is opposite to the light exit side; the cold-cathode lamp is positioned on the light incidence side of the light guiding plate; at least one surface of the cold-cathode lamp tube and the light incidence side of the light guiding plate form a nanometer silicon dioxide particle layer.

Description

【Technical field】 [0001] The invention relates to a backlight module structure of a flat panel display. 【Background technique】 [0002] The light source of the non-self-illuminating flat-panel display (such as liquid crystal display) comes from the flat light source module, the transmissive liquid crystal display uses the backlight module, and the reflective display uses the front light module. The backlight module is a module structure that converts linear light sources (such as cold cathode tubes) or point light sources (such as light-emitting diodes) into planar light sources with high brightness and surface uniformity. [0003] Li Haifeng and others pointed out in the article "Liquid Crystal and Display" Vol.18, No.1, 58-62 (February, 2003), "Technical Key Points of Light and Thin Backlight for High-quality LCD Displays", that the general LCD backlight module 10 consists of It consists of more than 20 components, but the components that affect the brightness and uniform...
