Abstract
A kind of total reflection projector, light source injects prism, it is reflected away by the total reflection principle light of prism by light, on the screen by lens projects, during total reflection, control is fixed on the reflecting surface of prism as cell array, by being dripped and prismatic reflection face contact to control as cell transparent is soft, since prism total reflection original after having leaching melting layer to contact above transparent soft drop with prism is destroyed, transparent soft drop and hyaline layer injection reflecting layer of the light by control as unit, light is reflected into another direction by reflecting layer.It thus prevents light from being totally reflected to project on screen, the contact area of control glass soft drop and prismatic reflection face is adjusted by voltage, for showing gray scale, such a control can control a pixel as unit, control passes through voltage control, the whole secondary picture of display as cell array.
Description
Technical field
The present invention relates to a kind of projection imaging apparatus, relate generally to image/video projection solution.
Background technique
Currently, present projection device is broadly divided into crystal projection and reflective mirror projection, crystal projection and reflective mirror are projected
It is at high cost that all structure is complicated, and crystal projection brightness is low, and reflective mirror projection manufacture difficulty is big, at high cost.
Summary of the invention
In order to overcome existing projection at high cost, structure is complicated, the deficiency of effect difference, and the present invention is former using prism total reflection
The projection to realize image/video is managed, controls total reflection by controlling as unit, achievees the effect that image projects.
The technical solution adopted by the present invention to solve the technical problems is: by photophore, allow light inject convex lens and
In concavees lens, light ray parallel is allowed to amplify, then allows light to be injected in prism, reflected by the total reflection principle of prism by light
It goes, allowing projection lens projects, during prism total reflection, control is fixed on the reflecting surface of prism as cell array on the screen,
By as cell voltage ceramic electrode voltage input, allowing voltage ceramic to push transparent soft drop and prismatic reflection face contact, thoroughly control
Bright soft drop makes of clear supple material, due to having leaching melting layer above transparent soft drop, after being contacted with prism extruding, and original rib
Mirror total reflection phenomenon is destroyed, light by control as unit it is transparent it is soft drop and hyaline layer enter reflecting layer, reflecting layer is light
It is reflected into another direction.Following black light-absorption layer absorbs the remaining light absorption that will do not reflected, and thus prevents light
Total reflection projects on screen, is adjusted by voltage, can control the contact area of transparent soft drop and prismatic reflection face, can control
The size of reflection light processed, so that it may show gray scale, such a control can control a pixel as unit, control as unit battle array
Column control many controls as unit by voltage, so that it may show whole secondary picture, control as the extinction prism around cell array can be with
Light extra around is reflected into other direction.
Present invention has the advantages that production cost can reduced and while difficulty of processing, due to controlling as unit battle array
Column are on-off action, and brightness is unaffected, improve display brightness, increase contrast.

Specific embodiment
In Fig. 1, light source 1 and convex lens 2, concavees lens 3 are connected, and rays pass through lens inject 4 the inside of prism, are passing through rib
Light 8 is injected projection lens 5 and projected above screen 17 by the total reflection of mirror reflecting surface, controls as cell array 7 and extinction prism 6
It is fixed on above prism 4.
In Fig. 2, control is fixed on above prismatic reflection face as cell array 7, and extinction prism 6 is fixed on control as cell array
Around 7.
In Fig. 3, it is around extinction prism 6 that control, which is arranged in control as 7 the inside of cell array as unit 16,.
In Fig. 4, light 8 is all-trans through prism 4 to be shot out, and transparent soft drop 14 is covered with leaching melting layer 9, transparent soft drop above
14 connect with hyaline layer 15, reflective layer 10, black light-absorption layer 11, voltage ceramic 12, and 12 lower end of voltage ceramic is electrode 13.
In Fig. 5, voltage is applied by electrode 13, transparent soft drop 14 is squeezed by the strength and prism 4 of voltage ceramic 12
Together, under the action of soaking melting layer 9, the total reflection of prism 4 is destroyed, and light 8 is through transparent soft drop 14 and hyaline layer 15, anti-
Photosphere 10 is reflected into another direction, and what is do not reflected is absorbed by black light-absorption layer 11.
Claims (2)
1. a kind of total reflection projector, wherein light source, convex lens, concavees lens, prism, projection lens are combined, and control is as single
Element array and extinction prism are fixed on above prism, control as in unit it is transparent it is soft drop with hyaline layer, reflective layer, black light-absorbing
Layer, voltage ceramic connection, it is characterized in that: applying voltage by electrode, transparent soft drop is contacted brokenly with prism by leaching melting layer extruding
Bad total reflection, prevents light from being totally reflected, and reaches the light control to single pixel point.
2. total reflection projector according to claim 1, it is characterized in that: control is to have many controls as unit as cell array
It is composed.
