Description
Technical field
The utility model is related to backlight production technical field, espespecially a kind of novel narrow frame backlight.
Background technology
Currently, cell phone back light source generally use plastic cement outline border or being integrally used as outline border with iron frame using glue modeling, glue on outline border
A photomask is pasted, is used to paste fixed optical film material on one side, in addition one side pastes liquid crystal display, is bonded and touches on display screen
Screen or glass cover-plate, touch screen or glass cover-plate are pasted onto on phone housing.This back light source structure is when carrying out drop test
White point, and side light leakage are will produce, the display effect of mobile phone is influenced.
Utility model content
To solve the above problems, the utility model offer is a kind of without white point, the lighttight novel narrow frame backlight in side
Source.
To achieve the above object, the utility model adopts the following technical scheme is：A kind of novel narrow frame backlight, packet
Light guide plate, reflector plate, diffusion barrier, bright enhancement film, photomask and LED light bar are included, the reflector plate is located at the lower section of light guide plate, described
The periphery of light guide plate is equipped with barricade, and the barricade, which encloses, is set as accommodation space, and the side of the barricade is equipped with light inlet, the diffusion
Film is located at bright enhancement film in accommodation space, and the photomask is located at the top of barricade, and the LED light bar is located in light inlet, institute
The outside for stating barricade is equipped with the point glue-line of light leakage.
Preferably, the diffusion barrier is located in accommodation space from the bottom to top with bright enhancement film.
Preferably, the light inlet is rectangular notch.
The beneficial effects of the utility model are：Traditional glue frame or glue iron construction are optimized for gear is arranged on light guide plate
