Abstract
The present invention provides a kind of display screen cover and its lampshade unit, the display screen cover includes: the lampshade unit of multiple lines and multiple rows arrangement, the lampshade unit includes: the staving of handstand shape, the top at the top is provided with arc sphere, by the convergence of top arc ball, gain light, make light either from the side or front is seen and can see similar light efficiency.
Description
Technical field
The present invention relates to video imaging technique field, in particular to a kind of display screen cover and its lampshade unit.
Background technique
In the prior art, the display screen being made of several small illuminator multiple lines and multiple rows matrixes is more and more common, this is aobvious
Display screen can change screen size according to different occasions, convenient and efficient.But several small illuminators, light source in it is dotted,
Light-emitting area is small, how to be in planar by point source of light, increases the light-emitting area of illuminator, be current urgent problem.
Summary of the invention
The present invention provides a kind of display screen cover and its lampshade unit, the knot of the staving of handstand shape and its top surface arc sphere
It closes, keeps uniform light scattering, guarantee brightness, image fault smaller, making light, either still front is seen and can be seen from the side
To similar light efficiency.
To achieve the goals above, the present invention is the following technical schemes are provided: the lampshade unit 12 includes: positioned at lower part
The top surface of the staving 122 of cover 124 and superposed handstand shape, the staving 122 is provided with arc sphere 121.
Preferably, 122 lower part of staving setting has the arcuate space 123 to arch upward.
Preferably, the side bottom of lampshade unit 12 has a pin hole 11.
The present invention also provides a kind of display screen cover, the row of the lampshade unit as described in any of the above-described technical solution of multiple lines and multiple rows
It arranges.
Preferably, the side of the display screen cover is provided with pin hole.
By implementing above technical scheme, have following technical effect that the present invention provides a kind of display screen cover and its lampshade
Unit, make light scattering uniformly, guarantee that brightness, image fault are smaller, make light either from the side or see can in front
See similar light efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of lampshade unit provided by the invention；
Fig. 2 is the internal structure cross-sectional view of display screen cover provided by the invention；
Fig. 3 is the structural schematic diagram (left view) of display screen cover provided by the invention.
Specific embodiment
For a better understanding of the technical solution of the present invention, the implementation that the present invention is described in detail provides with reference to the accompanying drawing
Example.
The present invention provides a kind of display screen cover and its lampshade unit, and as shown in Figure 1-Figure 3, the lampshade unit 12 includes:
Positioned at the cover 124 of lower part and the staving 122 of superposed handstand shape, the top surface of the staving 122 is provided with arc sphere
121.The arc sphere 121 of staving 122 and upper surface is integrally formed, and in other embodiments, is also possible to separately to set up.By
In multiple lines and multiple rows in the prior art lampshade unit 12 using flat-top, cause the brightness that is seen from the side to be seen with from front
Brightness is different, causes the distortion of image larger, and the arc sphere 121 of the present embodiment plays the role of convergence, gain light,
The light that each lampshade unit issues can be utmostly seen in the side direction of display screen cover, image fault is smaller.Light
After reflecting a distance by arcuate space, light enters staving, and for staving by after light homogenous diffusion, light reaches barrel-shaped top surface
Arc sphere, for arc sphere by the optically focused and gain effect of light of self structure, the light that staving was scattered is further
Convergence, increases the brightness of light.The combination of staving and its top surface arc sphere makes light scattering uniformly, guarantees brightness, make light
Either from the side or front is seen and can see similar light efficiency.
In other embodiments, on that basi of the above embodiments, further, the lower part of the staving 122 is provided with arch
The arcuate space 123 risen.In the present embodiment, it is preferred that the arcuate space 123 can arch upward for the upward of arc, in other realities
It applies in example, is also possible to the semicircle shape to arch upward upwards, spherical or other shapes, be also possible to arching upward upwards for multi-segment structure.Hair
Body of light 2 is mounted on 124 lower section of cover, and the light that illuminator 2 issues is collected at the cover 124 and is constituted with staving 122
Accommodation space in.The angle of divergence of 123 increasing light of arcuate space is conducive to the viewing of wide-angle direction.Due to light light
Three primary color theory, compared with the existing technology in there is no the flat-tope structure of light refraction distance, light light not to reflect, light
The inadequate defect of the uniformity, arcuate space of the invention make light reflect a bit of time and distance in arcuate space, and
Appear light from the big convex lens formed in arcuate space, color bleeding degree can be more uniform between three colors.
In other embodiments more specifically, pin hole 11 is arranged in the side bottom of display screen cover 1, and the pin hole 11 solves
It is difficult to the problem of dismantling in 1 use process of display screen cover, pin hole 11 is gently chosen by needle point or other elongate articles, it can be easily fast
The disassembly of prompt completion display screen cover.In the present embodiment, the pin hole 11 can be set in four sides of display screen cover 1
Bottom, middle part, top or other easy-to-dismount positions, the number of pin hole can be one or more etc., the shape of the pin hole 11
Shape can be round, semicircle, rectangular or other shapes easy to disassemble.
The embodiment of the present invention also provides a kind of display screen cover, including any described in above-described embodiment by multiple lines and multiple rows
Lampshade unit arranges.
In other embodiments more specifically, the side of the display screen cover is provided with pin hole, and the pin hole can be with
Each positions such as the top, middle part, lower part of display screen cover are set.
It is provided for the embodiments of the invention a kind of display screen cover above and its lampshade unit is described in detail, for
Those of ordinary skill in the art have change according to the thought of the present invention in specific embodiments and applications
Place, in conclusion the contents of this specification are not to be construed as limiting the invention.
