Abstract
The utility model discloses a mobile phone backlight plate with a novel light guide plate structure. The backlight plate includes an LED light source, a light shading sheet, a light intensifying layer which is formed through superposing an upper light intensifying sheet, a lower light intensifying sheet and a diffusion sheet, a light guide plate, a reflection sheet and a glue iron frame; a light entering end of the light guide plate is provided with a first wedge-shaped protrusion and a second wedge-shaped protrusion; the protruding end of the first wedge-shaped protrusion of the light guide plate is provided with the LED light source which is corresponding to a cut edge; the upper part of the LED light source is connected with the flexible circuit board; the flexible circuit board covers the LED light source and the first wedge-shaped protrusion; the flexible circuit board and the light intensifying layer are clamped between the light guide plate and the light shading sheet; the flexible circuit board and the light intensifying layer are arranged horizontally, and an interval between the flexible circuit board and the light intensifying layer forms a light leakage region; the second wedge-shaped protrusion of the light guide plate is corresponding to the light leakage region, and can refract leaked light back into the light guide plate; and the reflection sheet and the glue iron frame are arranged below the light guide plate. According to the mobile phone backlight plate of the utility model, the light guide plate is additionally provided with two wedge-shaped slopes, and therefore, the light source can be fully utilized, and cost can be saved, and brightness can be improved.
Description
Technical field
The present invention relates to mobile phone technique field, be specially a kind of mobile phone backlight plate with Novel light guide plate structure.
Background technology
Display screen market trends towards slimming and the high pixel of high brightness at present.In order to realize high pixel, need to increase LCD plate filter, but this can make the light transmission rate of LCD decline, cause the brightness of whole screen to decline.In order to overcome this problem and the requirement that meets market, brightness requirement backlight is also progressively raising.LCD module for display screen is divided into LCD plate and two parts backlight substantially.The performance of LCD occupies a part, and the embodiment of optical efficiency occupies a part too, and according to characteristic backlight, raising optical efficiency embodies the effect of image.
But a kind of mobile phone backlight plate with Novel light guide plate structure there is not yet report.
Utility model content
The purpose of this utility model is to overcome prior art deficiency, and a kind of mobile phone backlight plate with Novel light guide plate structure that makes full use of light is provided.
For achieving the above object, the technical scheme that the utility model adopts is:
A mobile phone backlight plate with Novel light guide plate structure, backlight comprises: LED light source, anti-dazzling screen, the lustre adding layer, light guide plate, reflector plate, the glue chase that are formed by stacking by upper and lower brightening piece and diffusion sheet; Described light guide plate light inputting end is provided with the first wedge-shaped projection and the second wedge-shaped projection; The corresponding trimming of the first wedge-shaped projection projecting end of described light guide plate is provided with LED light source; LED light source top is connected with flexible PCB, and this flexible PCB covers LED light source and the first wedge-shaped projection; Between described light guide plate and anti-dazzling screen, be folded with flexible PCB and lustre adding layer; Described flexible PCB and lustre adding layer are horizontally disposed, and interval between the two forms light leak district; The second wedge-shaped projection setting corresponding to light leak district of described light guide plate, returns the anaclasis of missing in light guide plate; Described light guide plate bottom is provided with reflector plate and glue chase.
The beneficial effects of the utility model are:
1, the utility model increases the wedge shape gradient in light guide plate, and the maximum light that light source is sent makes full use of, and has not only provided cost savings but also has improved brightness.
2, the utility model novel structure, remarkably productive, and production cost is low, and efficiency is high.
3, the utility model Technique Popularizing is strong, can be the greatly cost-saving spending of enterprise.
