Description
Technical field
The utility model is related to back light source technique fields, more particularly to a kind of Novel backlight.
Background technology
In existing side-light backlight, a circle light-shielding sheet is pasted with around light guide plate, the purpose is to by light source
The light that reflective membrane is reflected carries out leakproof light processing, but the light guide plate being treated at present with light-shielding sheet is to light leakage
Treatment effect is bad.
Also, the brightness of existing backlight is difficult to reach good globality even results, and light guide plate is difficult to generate
The effect of the reflection light of continuity, needs the setting for increasing light source, improves production cost, while reducing the matter of imaging
Amount.
Utility model content
Based on this, it is necessary to which the problem of being easy light leakage, brightness irregularities for backlight provides a kind of Novel backlight.
A kind of Novel backlight, including glue frame and the light guide plate that is arranged in the glue frame, the glue frame are led close to described
The side of tabula rasa incidence surface opens up lamp bar slot, and lamp bar is provided in the lamp bar slot,
Covering is provided with the first reflective membrane in the lamp bar slot, and anti-dazzling screen, the anti-dazzling screen lid are provided on the glue frame
Together on the lamp bar slot, the side of the glue frame far from lamp bar slot of stating is provided with the second reflective membrane,
It is provided with diffusion barrier on the light-emitting surface of the light guide plate, if the light guide plate is coated with close to the one side of the glue frame
Do the reflective basic point of rectangular distribution.
Spacing in one of the embodiments, between the two reflective basic points is reflective towards described second along the lamp bar
The direction of film tapers into.
Above-mentioned Novel backlight, covering is provided with the first reflective membrane in lamp bar slot, and is shared with anti-dazzling screen lid, can be to prevent
Only lamp bar installation place light leakage, and light guide plate is coated with the reflective basic point of several rectangular distributions by the one side of glue frame, can generate
Have the effect of that the reflection of continuity is bright, improves bright globality even results.
Description of the drawings
Fig. 1 is the structural schematic diagram of the Novel backlight of one of embodiment.
Specific implementation mode
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, below in conjunction with the accompanying drawings to this
The specific implementation mode of utility model is described in detail.Elaborate many details in order to abundant in the following description
Understand the utility model.But the utility model can be much to implement different from other manner described here, this field
Technical staff can do similar improvement without prejudice to the utility model connotation, therefore the utility model is not by following public affairs
The limitation for the specific embodiment opened.
As shown in Figure 1, a kind of Novel backlight, including glue frame 1 and the light guide plate 2 that is arranged in glue frame 1, glue frame 1 are close
The side of 2 incidence surface of light guide plate opens up lamp bar slot 11, and lamp bar 3 is provided in lamp bar slot 11.
Covering is provided with the first reflective membrane 4 in lamp bar slot 11, anti-dazzling screen 5 is provided on glue frame 1, anti-dazzling screen 5 is covered on lamp
In bar groove 11, states side of the glue frame 1 far from lamp bar slot 11 and be provided with the second reflective membrane 6.
Diffusion barrier 7 is provided on the light-emitting surface of light guide plate 2, light guide plate 2 is coated with several rectangular close to the one side of glue frame 1
The reflective basic point 21 of distribution.
Above-mentioned Novel backlight, the interior covering of lamp bar slot 11 is provided with the first reflective membrane 4, and is shared with the lid of anti-dazzling screen 5, can
To prevent 3 installation place light leakage of lamp bar, and light guide plate 2 is coated with the reflective basic point of several rectangular distributions by the one side of glue frame 1
21, can generate has the effect of that the reflection of continuity is bright, improves bright globality even results.
In one of the embodiments, the spacing between two reflective basic points 21 along lamp bar 3 towards the direction of the second reflective membrane 6
It tapers into.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
