The novel principle of work of this use is following:
As shown in Figure 1; The ruddiness R that 11R sends at first sees through the reflecting surface that first light source reflector 22 is injected secondary light source catoptron 23 along Y direction; Secondary light source catoptron 23 is 45 degree configurations with respect to coordinate system, and R is reflected away along X-direction by secondary light source catoptron 23, gets into compound eye system 12.Be divided into plural penlight entering collector lens 13 through the R of compound eye system and carry out optically focused, get into the polarizer 14 afterwards, because the polarizer 14 surfaces are provided with the ps diffusion barrier; Be separated into RP and RS to light, wherein RP sees through the polarizer 14, advances along X-direction; Advance in the other direction along the Y axle behind the separated back reflection of RS; RP, RS after first catoptron 15 and 16 reflections of second catoptron, get into pairing field lens 17 respectively, and field lens 17 is injected liquid crystal board 18 after transferring RP, RS to approximate directional light; Liquid crystal board 18 transfers RP, RS to image light according to the video signal of redness part.Image light projects polarized light reflective viewing screen 21 through projection camera lens 20 after synthesizing through polarization light compositing prism 19, just can obtain the projected picture (P and S) of two different polarization light components.
Use specific polarised light glasses, for example, when using the left and right sides eyeglass polaroid that 90 degree are vertical each other, just can make right and left eyes see different pictures, thereby reach three-dimensional viewing effect.
If when to use left and right sides eyeglass be unidirectional polaroid, just can watch in two polarized light component projected pictures.According to the video signal of being imported, projection when can realize two picture supplies two types of different spectators that like to appreciate simultaneously.
After 11R lit a lamp and accomplishes, 11G began to light a lamp.Earlier after first light source reflector 22 gets into compound eye system 12 with the reflection of secondary light source catoptron 23 reflectings surface, all the other trends are identical with above-mentioned R for green glow G, and liquid crystal board is according to the video signal of green portion, are converted into projection behind the image light to GP, GS.
After 11G lit a lamp and accomplishes, 11B began to light a lamp.Blue light B sees through secondary light source catoptron 23 and gets into compound eye systems 12, and all the other trends of blue light B are identical with above-mentioned R, and liquid crystal board is according to the video signal of blue portion, is converted into projection behind the image light to BP, BS.
And then get back to 11R and light a lamp.Repeat above-mentioned circulation and carry out Projection Display, utilize the ghost characteristic of human eye to reach the effect that picture is watched.If when liquid crystal board is imported same video signal, also can appreciate common two-dimensional picture.
The disclosed polarization type projection display equipment of the utility model has realized adopting a projector just can realize the purpose of 3-D effect, has reduced the usage quantity of projector; And, through original color liquid crystal plate is replaced by the black-and-white crystal plate, thereby simplified the one-piece construction and the floor area of display device, reduce manufacturing cost, conveniently debug.
In addition, effects such as the LED light fixture has that volume is little, power consumption is low, long service life and high brightness, environmental protection low in calories adopt the LED lamp as light source, can effectively guarantee drop shadow effect, improve image quality.
More than be description,, make this area professional and technical personnel can realize or use the utility model through above-mentioned explanation to the disclosed embodiments to the utility model embodiment.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
