Abstract
The utility model discloses a kind of bright enhancement film, backlight and liquid crystal module.The bright enhancement film includes basic unit, the layers of prisms of adding lustre to that is arranged in the basic unit, covered with refracting layer in the layers of prisms of adding lustre to, so that light is projected with specific direction.The bright enhancement film is in addition to enhanced shine, moreover it is possible to light is projected with specific direction, makes the light luminance of backlight and liquid crystal module in certain viewing angles maximum.
Description
Technical field
It the utility model is related to field of backlights, more particularly to a kind of bright enhancement film, backlight and liquid crystal module.
Background technology
Backlight is component important in liquid crystal module, light of the usual liquid crystal module requirement perpendicular to the direction on its surface
Brightness is maximum, and therefore, backlight can make all light in design using the prism structure that adds lustre on bright enhancement film come refracted light
As far as possible with perpendicular to the injection of the direction on liquid crystal module surface.But in some application-specifics, it is not required that liquid crystal module is being hung down
The upward light luminance of Nogata is maximum, in addition it is completely black in vertical direction can also, for example in vehicle-mounted product, liquid crystal module is set
On console between in the car, and driver's seat and front passenger's seat respectively be located at liquid crystal module both sides, in order that driver's seat and
People on front passenger's seat can be most it can be clearly seen that picture, then light luminance of the liquid crystal module needs in certain viewing angles be maximum.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of bright enhancement film, backlight and liquid crystal module.
The bright enhancement film is in addition to enhanced shine, moreover it is possible to light is projected with specific direction, makes backlight and liquid crystal module in certain viewing angles
On light luminance it is maximum.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of bright enhancement film, including basic unit, the layers of prisms of adding lustre to that is arranged in the basic unit, cover in the layers of prisms of adding lustre to
There is refracting layer, so that light is projected with specific direction.
Further, the refractive index of the refracting layer is higher than the layers of prisms of adding lustre to.
Further, the surface of the refracting layer is plane.
A kind of backlight, including framework, the light guide plate that is arranged in the framework and be arranged on the light guide plate and enter light
The lamp bar in face, above-mentioned bright enhancement film are arranged on the exiting surface of the light guide plate, and the refracting layer is away from the light guide plate
One side.
Further, an at least optical film is provided between the exiting surface of the light guide plate and the bright enhancement film.
Further, it is provided with reflector plate in one side of the light guide plate away from exiting surface.
Further, it is provided with anti-dazzling screen on the framework.
A kind of liquid crystal module, including above-mentioned backlight.
The utility model has the advantages that：The bright enhancement film covers one layer of refracting layer in the layers of prisms of adding lustre to,
Light is injected in the bright enhancement film from the back side of the basic unit, after the first time refraction by the layers of prisms of adding lustre to, different directions
Light assembled, and enter in the refracting layer, then after second of refracting layer refraction, with specific direction
Projected to both sides, not only acted as enhanced shine, moreover it is possible to light is projected with specific direction, make backlight and liquid crystal module in spy
The light luminance determined on visual angle is maximum.
Brief description of the drawings
