Abstract
A television projector capable of playing stereoscopic images, characterized in that: it comprises the following components: ceramic filter LB, high frequency amplifying IC1Demodulation circuit IC2The decoder and the three projection tubes form a double-image-channel stereo playing device. An optical polarizer is placed in front of the six projection tubes of the two channels. The utility model discloses can show three-dimensional TV program, can be used to fields such as scientific research, teaching, broadcast, recreation.
Description
The utility model relates to a kind of TV projector.
At present, common projector is an image channel, therefore can only play common image frame.Described image channel is partly formed by amplifying demodulation, decoding etc., decomposite red, blue, green three kinds of signals through decoded picture signal, and driving red (R), blue (B), green (G) three projection tubes respectively, three projection tubes are incident upon it on screen respectively, constitute a width of cloth coloured image.
The purpose of this utility model is to provide a kind of television projector of playing stereo-picture.
Realization key of the present utility model is: comprise by two: ceramic filter LB, high frequency amplify IC
1, demodulator circuit IC
2, PAL or N standard decoder and three three-dimensional playing devices of dual image passage that projection tube is formed; By three projection tube vertical arrangements of each passage, the horizontal adjacent spread pattern of the projection tube of two passage corresponding color distributes described twin-channel projection tube respectively; Be provided with an optical polarizer in six projection tube the place aheads.
The utility model can make projector play out the image with stereoeffect.
The drawing explanation:
Fig. 1 is the circuit diagram of an image channel of the present utility model.
Fig. 2 is the distribution schematic diagram of six projection tubes of dual image passage of the present utility model.
The utility model is delivered to two corresponding three-dimensional playing devices of being made up of the projection tube of three vertical arrangements with same signal respectively by two image channels.Wherein one group of projection tube the place ahead is provided with the horizontal polarization sheet, and another group projection tube the place ahead is provided with the vertical polarization sheet, and the horizontal adjacent arrangement of the projection tube of every group of corresponding color.The three-dimensional playing device that is made of above-mentioned six projection tubes is when projection, and the beholder can wear a polarising glass, and its left eyeglass lens is a horizontal polarization direction, and right eye is a vertical polarization.The utility model can be shown three-dimensional television, and produces real image effect, can be used for fields such as scientific research, teaching, broadcasting, recreation.
