Scanning element changes the static prism structures in the conventional art into the motion prism structures, is provided with to have the rotating shaft 81 of level and the prism 8 of vertical balance staff 82.The travel(l)ing rest 83 of second motor 86 and prism 8 is housed on the rotating shaft 81, and fork is equipped with at the center of travel(l)ing rest 83, and fork links to each other with housing 1 by hinge.Travel(l)ing rest 83 cooperates and links to each other with housing 1 by back-moving spring 87 by driving lever 88 is movable with cam 84 on being located at the 3rd motor 89 main shafts.
With reference to Fig. 3-Fig. 5, image processing circuit plate 4 has DSP or FPGA picture processing chip U1.U2, U3 are the FLASH program storage, are 29LV800BB with reference to model, 1M * 8 FLASH.U10, U11 are SDRAM, are V54C365164VD with reference to model.U4 receives the VGA vision signal, comprises RED, GREEN, BULE, horizontal-drive signal HSYNC, vertical synchronizing signal VSYNC.The U5-U9 that links to each other with bus exports various control signals, comprising: U5 provides micromachine stepless time adjustment control signal E_COTROL1-4 speed control, the control of E_COTROL5-8 angle.U6, U8 provide other control signals: the control of COTROL1 color; the COTROL2 brilliance control; the COTROL3-4 focus control, the control of COTROL5-6 line output, COTROL7-8 row output control; the control of COTROL9 contrast; COTROL10-11 output time control, the control of COTROL12 power down protection, the COTROL13 control of shutting down; COTROL14 distortion control, COTROL15 sound time delay Synchronization Control etc.U7 is the control triggering signal, and U9 provides two-way control signal.
Behind the circuit start, chip is connected to described luminescence unit by time sequence output T-RGB row, column dot matrix signal; Simultaneously, chip is exported corresponding control signal by the time sequence and is connected to motor control unit.Driving through motor control unit first motor, second motor and the 3rd motor, the light by the control of row, column dot matrix signal of luminescence unit output passes through optical convergence unit and scanning element, the continuous coloured image that prism 8 output is made up of T-RGB row, column light can satisfy the vision requirement of 24 frame/seconds of human body and be projected to screen through window 3.
With reference to Fig. 6-Fig. 8, when the main program of picture processing chip execution graph 6 and the subprogram of Fig. 7-Fig. 8, the standard RGB row, column signal of input is given the temporal characteristics of row, column signal respectively.Simultaneously, the T-RGB speed control signal of the free feature of output device is controlled the operation of first motor, second motor and the 3rd motor respectively.In special time, drive the prism rotation and determine mirror angle.When second motor and the 3rd motor-driven prism carry out the minute surface conversion and when carrying out angular transformation, stop the output of T-RGB signal automatically.
Have under the acting in conjunction of temporal characteristics T-RGB row, column control signal,,, finish next column output on next plane finish a row output with one side because prism is pressed the certain speed rotation with axle 81 and swung with axle 82.Equal the angle of reflection principle according to angle of light, the fixed position has temporal characteristics three primary colors focused light when shining the arbitrary minute surface of prism, produces the reverberation with the incidence angle equal angular.When prism rotated an angle with certain speed, incidence angle just produced and changes, thereby changes angle of reflection, so just made reverberation, shone the same horizontal line diverse location on arbitrary plane.When prism rotates with a stabilized speed, just on same horizontal line, stay a light vestige.Because incident ray is produced by the three primary colors emitter, has just stayed the three primary colors hot spot by Colour composition.And when prism rotated, these hot spots just stayed a line of being made up of many colored hot spots.Because vision difference and visual light are detained principle, when primaries with certain speed, when forming the hot spot line, in human eye, demonstrate a continuous visible colourama line with Colour composition.
Range of application of the present invention is wider, can be integrated in wall-hanging image and play television set inside, and replacing kinescope becomes novel broadcast visible light film and television system.Can be integrated in the computer, and replace picture tube in the computer display.Can be integrated in portable smaller size smaller interior of articles, and make this portable object have image playback function, as see a film, surf the web etc.As be integrated in mobile phone and form and to have broadcast and be not subjected to the restriction of mobile phone screen size, playing video function.Be integrated in notebook and form and to have broadcast and be not subjected to the restriction of computer display screens size, play also explanation playing video function.
For example the video image playing device is integrated in the notebook, the any content that on the notebook chromatic liquid crystal screen, shows then, all can be by the video image playing device with the color visible form, screen (as white wall) shows before video image playing device camera lens, is not subjected to the notebook volume restrictions and shows identical visible images with this computer LCDs.
For example the video image playing device is integrated in and plays among the video image mobile phone, the any content that on this mobile phone chromatic liquid crystal screen, shows then, all can be by the video image playing device with the color visible form, screen (as white wall) shows before video image playing device camera lens, is not subjected to play video image mobile phone volume restrictions and shows identical visible light pattern with this liquid crystal display screen of mobile phone.
For example the video image playing device is integrated in existing television set or the computer display, and replaces picture tube, just can reduce television set or display volume, economize on electricity, vision protection (similar seeing a film), and reduce electromagnetic radiation.
