Abstract
The invention discloses a high contrast ambient light interference preventing screen, comprising a curtain; colour blocks of four colours are coated on the curtain; the four colours respectively are red, green, blue and specific colour; the specific colour is any one of red, green, blue, cyan, yellow, purple, black, white and gray; the sum of the areas of adjacent four colour blocks is less than or equal to the size of a pixel point; reflection of ambient white light is reduced by arranging the colour blocks of various colours on the surface of the projection curtain; nearly 50% of the ambient white light irradiating on the curtain is absorbed; the projection contrast is improved; and the ambient light interference is reduced.
Description
Technical field
The present invention relates to projector equipment field, particularly relate to the screen of a kind of high-contrast, the interference of environment resistant light.
Background technology
Projector to be applied in every field all more and more general.But, be easily subject to ambient light effects as the projection screen of projector's image forming medium, drop shadow effect declined, also limit the application of projector in a lot of field.Be widely used in the projection screen of front projection image forming medium at present, great majority are all simple reflecting curtains.Projection screen directly reflexes to the eyeball of beholder the light that projector launches, but this simultaneously, also can the eyeball of non-for other in environment projector light line reflection to beholder, the light entering the eyeball of beholder is like this exactly projector's light and the mixing of ambient light, ambient light is stronger, mixes the fewer in the accounting entering all light in people's eyeball of rear useful projection ray.And the accounting of projection ray, directly have influence on the viewing effect of human eye.
Summary of the invention
The object of this invention is to provide the screen of a kind of high-contrast, the interference of environment resistant light, lay the color lump of shades of colour on the surface of curtain, reduce the reflection of ambient white light, improve projected contrast, reduce the interference of surround lighting.
From colour mixture principle, be mixed into shades of colour by red, green, blue three primary colors.Free mixed-color method and spacing color mixed method two kinds in mixed-color method.The colour mixture principle of current various projector substantially all adopts red-green-blue or red-green-blue to add certain particular color (as white) etc. and mixes.And in the natural white light of environment, except comprising above-mentioned primary colours, orange, yellow, the composition such as cyan, purple in addition, these unnecessary compositions, will directly affect the effect of projection.The present invention utilizes spacing color mixed method to reduce projector coloured light out cleverly, and reduces the reflection of surround lighting to greatest extent to the greatest extent, to ensure that human eye can see the raw frames of more pressing close to projector and projecting.
Technical scheme of the present invention is the screen of a kind of high-contrast, the interference of environment resistant light, comprise curtain, described curtain is coated with the color lump of four kinds of colors, described four kinds of colors are respectively red, green, blue and special color, described special color be in redness, green, blueness, cyan, yellow, purple, black, white and grey any one, the area sum of 4 often adjacent color lumps is less than or equal to the size of a pixel.
Further, described color lump is reflectance coating or coating.
Further, the material that described reflectance coating adopts is calcium fluoride.
Further, the material that described coating adopts is pearl essence or look cake.
Further, color lump is rectangle or circle.
Beneficial effect: lay the color lump of shades of colour on the surface of projection screen, decrease the reflection of ambient white light, the ambient white light injecting curtain has and is absorbed close to 50%, improves projected contrast, reduces the interference of surround lighting.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of curtain;
Fig. 2 is the schematic diagram of the curtain with another kind of color lump distribution mode;
Fig. 3 is the schematic diagram of the curtain with another kind of color lump distribution mode;
The schematic diagram of Fig. 4 to 6 to be color lumps be circular curtain.
Mark in figure: 1-color lump.
Embodiment
Below in conjunction with accompanying drawing, preferably embodiment of the present invention is described in further detail:
Composition graphs 1 to Fig. 6, the screen of a kind of high-contrast, environment resistant light interference, comprise curtain, described curtain is coated with the color lump 1 of four kinds of colors, described four kinds of colors are respectively red, green, blue and special color, described special color be in redness, green, blueness, cyan, yellow, purple, black, white and grey any one, the combination of different colours, can reach different effects.
Each color lump 1 size can adjust arbitrarily, but the area sum of 4 often adjacent color lumps 1 is less than or equal to the size of a pixel, such as, calculates with four color lump 1 mean size examples.One piece 100 inches, length breadth ratio is the curtain of 16:9, and the size of its each pixel is X*Y, and the size of so each color lump 1 is (X/4) * Y, or X*(Y/4), or the dot combination that radius is suitable.
The color lump 1 of different colours is evenly distributed on curtain, is convenient to the light of the color lump 1 uniform pickup corresponding color on screen, makes screen improve contrast uniformly, reduce the interference of surround lighting equably.
Described color lump 1 is reflectance coating.The reflection characteristic of the reflectance coating of each color lump 1 must in the wavelength coverage of certain color.Such as, the reflectivity of red block 1 must be that the light being 620 to 740 nanometers to wavelength plays a part to strengthen reflection, other light absorption.If the wavelength coverage of each RGB monochrome of some projector is very narrow, the reflectance coating that can reduce monochromatic block 1 further works the scope of the wavelength strengthening reflex, can have the effect that better environment resistant light disturbs.
Described color lump 1 also can be coating.The reflection characteristic of each coating must in the wavelength coverage of certain color.Such as, the reflectivity of green block 1 must be that the light being 500 to 565 nanometers to wavelength plays a part to strengthen reflection, other light absorption.If the wavelength coverage of each RGB monochrome of some projector is very narrow, the coating that can reduce monochromatic block 1 further works the scope of the wavelength strengthening reflex, can have the effect that better environment resistant light disturbs.
The materials calcium fluoride that described reflectance coating adopts.
The material that described coating adopts is pearl essence.
Described coating also can adopt look cake.
Composition graphs 1 to 3, color lump 1 is rectangle, and the color lump 1 of different colours is uniformly distributed and closely covers on curtain, decreases the reflection of ambient white light, improves projected contrast, reduces the interference of surround lighting.
Composition graphs 1, special color is white.
Composition graphs 2, special color is black.
Composition graphs 3, special color is yellow.
Composition graphs 4 to 6, color lump 1 is circular, and the size of each circle is identical with area, and the color lump 1 of different colours is uniformly distributed and closely covers on curtain, decreases the reflection of ambient white light, improves projected contrast, reduces the interference of surround lighting.
Composition graphs 4, special color is white.
Composition graphs 5, special color is black.
Composition graphs 6, special color is yellow.
Lay the color lump 1 of shades of colour on the surface of projection screen, decrease the reflection of ambient white light, the ambient white light injecting curtain has and is absorbed close to 50%, improves projected contrast, reduces the interference of surround lighting.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
