Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Fig. 3 is the structural representation for the display screen that the embodiment of the present invention one provides.As shown in figure 3, what the present embodiment provided
Display screen includes reflecting prism 1, and the side of reflecting prism 1 is plane, and opposite side is zigzag reflecting surface 10, and reflecting surface 10 wraps
Multiple first reflectings surface 11 and multiple second reflectings surface 12 are included, for the first reflecting surface 11 towards the projection light source of display screen, second is anti-
It is different from the direction of the first reflecting surface 11 to penetrate face 12, each first reflecting surface 11 is provided with projection 111, and projection 111 is in level side
Upward different parts have different-thickness, so as to the incident ray of the first reflecting surface 11 is radiated at after projection reflects, institute's shape
Into emergent ray where perpendicular and incident ray where perpendicular there is angle.
Wherein, display screen uses mainly as the projection screen of laser television.Laser television may include as projection light source
Laser-projector and the display screen that is projected.Laser-projector can utilize All-Solid working-laser material,
Produce the continuous laser of three kinds of wavelength of red, green, blue.When carrying out the broadcasting of image or film, image or video data are sent to
On modem inside laser-projector, data are converted into optical information by amplitude modulation, and RGB is carried so as to be converted into
The laser beam of different colours, and the laser beam comprising all image informations is sent to the projection of laser-projector by optical cable again
Head, finally project on display screen, complete projection.
Wherein, because laser-projector is approximately spot light, display screen is as the projection screen for reflection laser beam
Curtain, is usually located at the focal position of laser-projector emergent ray, and can reflect the incident ray sent by laser-projector
For parallel emergent ray, to form clearly projected image.In order to realize above-mentioned light reflecting effect, the reflecting surface of display screen
It is not the smooth plane of reflection, and generally includes the reflecting prism using Fresnel lens structure.Reflecting prism 1 is generally perpendicular
Straight to place, its side is smooth plane, and opposite side is zigzag reflecting surface 10.When in use, jagged reflection table
Face 10 can be towards projection light source, to carry out light reflection.Reflecting surface 10 includes multiple first reflectings surface 11 and multiple second
Reflecting surface 12.First reflecting surface 11 and the second reflecting surface 12 are towards different directions, wherein the first reflecting surface 11 is towards projection
Light source, can be as the key reflections plane of display screen.
Specifically, because the laser-projector as projection light source is generally arranged at close to display screen below or above
Position, so the first reflecting surface 11 is to tilting above or below display screen, and corresponding, as with the direction of the first reflecting surface 11
Different planes, the second reflecting surface 12 can tilt to display screen below or above.Such as laser-projector is under display screen
When side is set, the first reflecting surface 11 tilts down, and the direction of all first reflectings surface 11 is towards laser-projector.When sharp
Light projector is sent after forming the light of image, and reflecting surface 10 of the light through display screen is reflected, and is formed along water
Square to outgoing emergent ray, so as on a display screen formed be available for spectators watch projected image.
In order that display screen when carrying out light reflection, increases the angle of reflection light outgoing at left and right sides of display screen,
Projection 111 can be provided with each first reflecting surface 11,111 different parts in the horizontal direction of each projection have
Different-thickness, thus the surface of projection 111 is not a plane in the horizontal direction, but with the curved surface to rise and fall, Huo Zhechao
To the plane in multiple varying level directions.So when incident ray is radiated on the first reflecting surface 11, incident ray is through projection
After 111 reflections, projection 111 can change the shooting angle of light, the emergent ray to be formed is in different perpendicular from incident ray
In straight plane, i.e., the perpendicular where perpendicular and incident ray where emergent ray has angle, such emergent light
Component of the direction of line from the direction of incident ray in the horizontal direction is different, and incident ray, can be from aobvious after the reflection of projection 111
Direction outgoing at left and right sides of display screen, so as to improve the visible angle of display screen.
Specifically, projection 111 set on the first reflecting surface 11 both can be a larger-size projection, also may be used
Think multiple less projections of size being arranged side by side on the first reflecting surface 11.Because in the reflecting surface 10 of reflecting prism,
First reflecting surface 11 and the second reflecting surface 12 generally can be wide with whole reflecting surface, i.e. the first reflecting surface 11 and the second reflecting surface
12 size is larger.In order to adapt to the overall dimensions of the first reflecting surface 11, should make to be respectively provided with each first reflecting surface 11 more
The individual projection 111 for being used to change emergent ray direction, it can so ensure the Projection Display effect of whole display screen.
Compared with projection screen of the prior art, the display screen of the present embodiment can change emergent ray in the horizontal direction
Angle.Fig. 4 is the light reflection direction schematic diagram of projection screen in the prior art.Fig. 5 is that the embodiment of the present invention one provides
The light reflection direction schematic diagram of display screen.As Fig. 4 and Fig. 5 can be seen that, above-mentioned display screen is in the light sent to laser-projector
Line is reflected and during Projection Display, on the one hand incident ray can be reflected into the emergent ray being emitted in the horizontal direction, from
And the projected image for being available for spectators to watch is formed on a display screen；On the other hand, the projection set on the first reflecting surface can be with
Change emergent ray direction in the horizontal plane, make the perpendicular where the perpendicular and incident ray where emergent ray
With angle, so as to allow emergent ray to be emitted along direction at left and right sides of display screen, to improve the visible angle of display screen, strengthen seeing
Many viewing experiences.
In the present embodiment, display screen includes reflecting prism, and reflecting prism side is plane, and opposite side is that zigzag reflects table
Face, reflecting surface include multiple first reflectings surface and multiple second reflectings surface, the first reflecting surface towards display screen projection light source,
Second reflecting surface is different from the first reflecting surface direction, each first reflecting surface is provided with projection, it is raised in the horizontal direction
Different parts have different-thickness, so that the outgoing that the incident ray for being radiated at the first reflecting surface after projection reflects, is formed
The perpendicular where perpendicular and incident ray where light has angle.So formed on a display screen and be available for spectators
While the projected image of viewing, thus it is possible to vary the direction of emergent ray in the horizontal plane, make vertical flat where emergent ray
Face has angle with the perpendicular where incident ray, so as to allow emergent ray to be emitted along direction at left and right sides of display screen, with
The visible angle of display screen is improved, strengthens the viewing experience of spectators.
On the basis of above-described embodiment, it is specific that several raised differences on display screen reflecting surface are provided individually below
Structure type.
For example, the projection on the first reflecting surface can have arc-shaped structure.The normal direction of each point on circular arc
Differ, such incident ray from circular arc diverse location irradiate when, different directions can be reflected onto, thus circular arc can be utilized
The direction of characteristic changing emergent ray in the horizontal plane.Fig. 6 is a kind of reflecting prism that the embodiment of the present invention one provides
Partial structural diagram.As shown in fig. 6, on the basis of above-described embodiment, raised 111 surfaces are cambered surface, and projection 111 is in level side
The center thickness in upward section is more than edge thickness, so that cambered surface is convex to projection light source.
Specifically, the projection 111 on the first reflecting surface 11 can be arc surface, i.e., raised 111 section in the horizontal direction
Face is circular shape.Wherein, raised 111 section in the horizontal direction, the thickness of the center portion thereof point are more than the thickness of marginal portion
Degree, so that the cambered surface is convex to the outside of the first reflecting surface 11, i.e., raised 111 protrusion direction is towards projection light source.So throw
The light that shadow light source is sent can be reflexed to and former incident light after the reflecting surface reflection of display screen by the projection 111 of arc-shaped
Line left side or right direction, thus emergent ray reduces with the angle positioned at display screen left side or spectators' sight on right side, carries
The high viewing effect for being located at display screen side spectators, effectively improves the visible angle of laser television in the horizontal direction.
Optionally, the cross sectional shape of raised 111 in the vertical directions can keep equal everywhere, and so projection 111 is vertical
Section edges on direction are straight line, and the straight line is parallel with the first reflecting surface 11, so the light that projection light source is sent shines
Penetrate when in projection 111, the angle of reflection and the first reflecting surface 11 of raised 111 pairs of incident ray in the vertical directions are to incident ray
The angle of reflection of in the vertical direction is identical, thus display screen is constant to the reflection angle of incident ray in the vertical direction, so
The light path that can simplify between display screen and projection light source designs with focusing, so as to reduce the overall manufacturing cost of display screen.
In addition, optional, the surface of the projection 111 on the first reflecting surface 11 can also be hemisphere face, or other arcs
Face shape.When raised 111 surfaces be hemisphere face, because each position has a radian on hemisphere face, raised 111
Surface can produce reflection to incident ray, and emergent ray is deposited with incident ray in the vertical direction and in the horizontal direction
In angle.So surface be hemispherical raised 111 light can not only be reflexed to and former incident ray on the left of or right side side
To light can also being reflexed to above or below former incident ray.The thus projection 111 of this shape, can both improve
The visible angle of display screen in the horizontal direction, the visible angle of vertical direction can also be improved.
In addition it is also possible to the surface of projection 111 on the first reflecting surface 11 is set to be towards the inclined-plane at left and right sides of display screen, tiltedly
The normal and the first reflecting surface of discord in face are vertical, and are biased at left and right sides of display screen.When incident ray is by display screen front side
To after being radiated on inclined-plane, the law of incidence angle is equal to according to angle of reflection, emergent ray and incident ray can be with the methods on inclined-plane
Line is in equal angular, thus emergent ray will not reflect along face display screen direction, but to the left side or right side of display screen
Deflection.Fig. 7 is the partial structural diagram for another reflecting prism that the embodiment of the present invention one provides.As shown in fig. 7, reflection rib
The projection set on first reflecting surface of mirror is pyramid, and the summit of pyramid is towards projection light source.Projection is so arranged to pyramid,
Pyramid bottom surface is connected with the first reflecting surface, and pyramid summit is towards projection light source.Because the side of pyramid is reflected with reflecting prism
The first reflecting surface on surface forms an angle, can be with pyramid side and the so when incident ray is radiated on pyramid side
One reflecting surface angulation and to display screen side deviate.Reflecting surface of the light through display screen that so projection light source is sent
After reflection, by the offside reflection of projection to the direction different from former incident ray, such as the left side or right side of former incident ray, because
And emergent ray reduces with the angle positioned at display screen left side or spectators' sight on right side, obtain the visible angle of display screen
Improve.
Specifically, pyramid can be various shapes, such as the different profiles such as triangular pyramid, rectangular pyramid.The different shape of pyramid
The different reflecting effects of the first reflecting surface can be caused.Fig. 8 is the offer of the embodiment of the present invention one when projection is triangular pyramid
Light reflection schematic diagram.As shown in figure 8, projection 111 can be triangular pyramid, triangular pyramid has two sides towards projection light source
Face.When projection 111 is triangular pyramid, the bottom surface of triangular pyramid is connected with the first reflecting surface 11, and three sides of triangular pyramid are inclined to respectively
Different directions, two of which side is towards projection light source.
Such as when the laser-projector as projection light source is located on the downside of display screen, triangular pyramid projection 111 is wherein
Two sides are also facing lower section, and the 3rd side is upward.So, when laser-projector emits beam to display screen,
Projection 111 has two sides while to be irradiated by incident ray, and incident ray is reflexed to the first reflecting surface 11 respectively
The left and right sides, so as to increase the angular range of emergent ray in the horizontal direction, increase display screen visible angle.Because Rhizoma Sparganii
The side of cone is set towards the incident direction of projection light source as far as possible, so reflection effect of the side of projection 111 to projection light source
Fruit is preferable, and light ray energy loss is smaller, can realize less brightness of image loss.
In addition, the angular range of 111 reflection lights of projection on the first reflecting surface 11, shape and chi with projection 111
It is very little to have compared with Important Relations.Such as projection 111, when being pyramid-shaped, the deviation angle of raised 111 reflection lights depends on pyramid side
Face and the angulation of the first reflecting surface 11, and pyramid side and the angulation of the first reflecting surface 11 are by pyramid heights and pyramid
Base area is determined.And raised 111 outer surfaces are when being arc, the deviation angle of the reflection light of projection 111 then with arc
Curvature is relevant.The parameters such as height and surface curvature that thus can be by setting projection 111, the raised 111 pairs of light of adjustment are carried out
The horizontal angular range of reflection, change the horizontal viewable angle of display screen.
Further, water during raised 111 reflection light can also be adjusted according to the parameter of laser-projector and display screen
Flat angular range, such as can be reflective to projection 111 according to the focal length of laser-projector, or the screen size size of display screen
Angular range be adjusted, be optimal use viewing effect.
In order to which the light further reflected display screen is diffused, increase the visible angle of display screen, display screen is also
The structure for diffusing light can be included.Fig. 9 is the hierarchy schematic diagram for the display screen that the embodiment of the present invention one provides.Such as
Shown in Fig. 9, in display screen, the diffusion layer 2 for diffusing light can also be included, diffusion layer 2 is parallel with reflecting prism 1, and sets
Put in the side of reflecting surface 10 of reflecting prism 1.So when reflecting prism 1 is to the light from the incidence of the projection light sources such as laser-projector
After line is reflected, diffusion layer 2 can be passed through again, and increase exiting angle range under the diffusion of diffusion layer 2, so as to increase
The visible angle of whole display screen.
Specifically, diffusion layer 2 can also be hierarchy.For example, diffusion layer 2 can include substrate layer 21 and diffusion particle
22, substrate layer 21 be arranged in parallel with reflecting prism 1, and diffusion particle 22 is distributed in the side of the remote reflecting prism 1 of substrate layer 21.
Wherein, 21 layers of base material is generally by polyethylene terephthalate (Polyethylene terephthalate, letter
Claim PET) form.Because PET material has higher light transmittance and reflectivity (general up to more than 90%), using PET
The substrate layer 21 that material is formed can effectively connect reflecting prism 1 and diffusion particle 22, and diffusion particle 22 is uniformly laid in
On substrate layer 21, when light is by diffusion particle 22, the angle of emergent ray can be changed because of the reflection and refraction of diffusion particle 22
Degree, so as to being diffused through the light of diffusion layer 2, be more uniformly distributed emergent ray, exiting angle range is bigger.
