Abstract

A novel straight down back light reflection film comprises at least two LED light bars, a reflection film, a diffuser plate, a diffuser film, an upper prism and a lower prism, wherein the LED light bars are arranged on the reflection film, the diffuser plate, the diffuser film, the upper prism and the lower prism are arranged above the reflection film in sequence, the reflection film between the LED light bars is provided with a main reflection block, the two sides of the main reflection block are provided with secondary reflection blocks respectively which are symmetrical in numbers, and the height of the secondary reflection blocks are lower than that of the main reflection block. The novel straight down back light reflection film has the advantages that the structure is simple, brightness loss is compensated by increasing the reflective sheet area through the main reflection block and the secondary reflection blocks, the whole height of the reflection blocks is reduced but the reflection area is increased, and the problem of effectively reducing the bright line can be solved.

Description

A kind of Novel straight down type backlight reflectance coating
Technical field
The utility model relates to backlight reflectance coating technical field, is specially a kind of Novel straight down type backlight reflectance coating.
Background technology
Backlight is widely used in liquid crystal display module at present, and wherein directly-down liquid crystal shows module, comprises at least two LED lamp bars, reflectance coating, diffuser plate, blooming, upper prism and lower prism, and wherein the light-emitting area of LED lamp bar is called OD value to the distance of diffuser plate.As shown in Figure 1; for the direct-light-type backlight of two LED lamp bars 1, conventionally reflectance coating 2 mid portions are converted into triangle reflecting surface 3 to promote briliancy and the uniformity of central point, but this kind of structure has the generation of bright line conventionally; the folding line of the corresponding reflectance coating in bright line position, visual effect is not good.Conventional way is to rise the mist degree of blooming, and these ways will be sacrificed briliancy; Or reflectance coating 2 roulettes are beaten partly and broken, but bright line is improved to DeGrain.The discovery of experimental study simultaneously, intensity and the width of bright line can be modulated in reduction triangle reflecting surface 3 tops apart from the distance of diffuser plate, can bright line is dimmed apart from the distance of diffuser plate although reduce reflecting surface 3, can reduce center briliancy and all spend together.
Utility model content
The technical problem that the utility model solves is to provide a kind of Novel straight down type backlight reflectance coating, to solve the problem proposing in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of Novel straight down type backlight reflectance coating, comprise at least two LED lamp bars, reflectance coating, diffuser plate, diffusion barrier, upper prism and lower prism, described LED lamp bar is arranged on reflectance coating, reflectance coating top is provided with diffuser plate, diffusion barrier, upper prism and lower prism successively, reflectance coating between LED lamp bar is provided with principal reflection piece, principal reflection piece both sides are equipped with the secondary reflex block of symmetry number object, and the height of secondary reflex block is lower than the height of principal reflection piece.
Further, the reflector shape of described principal reflection piece, secondary reflex block is a kind of in symmetrical triangle, circular arc.
Further, increase successively to the height of principal reflection piece along the secondary reflex block near LED lamp bar.
The beneficial effects of the utility model are: the utility model is simple in structure, mode by principal reflection piece, secondary reflex block increase reflector plate area makes up the loss of brightness, reduce on the whole the height of reflex block but increased reflective surface area simultaneously, can effectively reduce bright line problem.
