equipped with the appropriate input device and the necessary recording equipment, in order to realize man machine contact and for later investigation by. Electron beam tube display device in display technique is still occupied the main position, but all board or wall display device (i.e., a matrix display ) superiority, will get developing quickly. Projection display technology has been flat screen display replaces the trend. Display software in intelligent display device is very important. Graphic language standardization, the wide application of computer display has a huge impact, thus great attention. Computer display technology development will promote the development of display software. A new image reconstruction technology makes full use of the advantages of the laser itself. In the light of the dissemination method, laser light source with the traditional incandescent lamp has a fundamentally different: ordinary incandescent light in all directions and laser emission, will all the light gathering in a parallel beam of light. In addition, the laser projector than traditional projector can express more color range, to provide more clear images. High definition allows the laser projector can be used for traditional projector is not applicable in some areas. The current widely used with halide lamp traditional projector cannot arbitrarily to around the room projection, projection lens compensation because only a very small distortion, so in principle should show near the axis of the projector, generally located in the center of the room. Laser irradiation in a vertical or horizontal angle of the screen, the effect is the same, no distortion. Even odd projection geometry, such as an arch screen, or even a circular screen, laser projection in any place will not produce ambiguous phenomenon. Laser projector such characteristics for annular projection to create a better future. In practical application, laser technology and many other advantages: compact projection head and laser unit can be separated; the laser unit can be hidden in the room, only the small projection head is exposed outside; the inclined projection distortion can be very simple correction etc.. Laser display is red, green, blue ( RGB ) of three primary colors of laser light source for the display technology, can the true reproduction of the objective world rich, bright colors, and provide more powerful expressive force. Compared with natural light color gamut, a conventional display device can only reproduce the human eye can see colors in 30% and currently under development in the laser display can cover 90%, the huge potential for us to laser display technology of the future is full of expectations, so the laser display is known as" the human visual revolution in history".
