Research Of Large Screen Laser Display Technology

The large screen laser display is a new fashioned technology. With the characteristics of high brightness, high directivity and high color saturation, the large screen laser display has the advantage that others can not compare with on the distinguishability and color . In this paper, the new project of using the Diode Pump Solid State Laser as the light source and double-galvanometer to scan has been advanced on the base of existing technology of the large screen laser display, and the feasibility has been analyzed. Combined the questions in the technology of laser large screen display with the development of the solid state laser and scanner, the new idea has been put forward that using the three primary colors state laser as the light source to carry out the line and frame scan by the two galvanometers. This subject researched Diode Pump Solid State Laser and the technology of color mixing, realizes the color modulation by the hardware technology to control brightness of Solid State Laser, studied the "pillow distortion" which is generated by scanning with double-galvanometer, promote the resolvent , designed the beam path system, and actualized the perform of the laser large screen display.This paper researches a new type technology of laser large screen display. This project is proved to be available, so it establishes a stable basis to implement the application of high-power laser that can be carried out large screen display in outside.
