Based On The Key Technology Of The Laser Light Source Projector Research And Development,

This paper describes project background and application value;Introduces the projector technological development; Expounds the development of laser display technology;Based on laser light around the DLP, research the projector; Related principles, techniques, technology and industrialization of research ; Research compact and small driving circuit; new Light valve control technology research and application, the color management, thermal design, etc; Make the laser light prototype, complete the EMC test and performance test, achieve the design goal.In the project, researches the detailed analysis of laser light, analyses the difference of the current source and laser light, design the specific technical solutions, design the power supply of the laser light and complete test. The driver circuit is DDP2230 circuit system of TI, design the software for the laser light. Combining the PCB technology and the EMC technology, I design the miniaturization driving circuit. Light valve control technology is to research the DMD (Digital Micromirror Display) controlling technology secondary. In the color design,by means of color combination formulas I research spectrum mapping through a series of software. The thermal design use strong convective thermal design by cooling fan, which ensure the normal work of the laser sources and the semiconductor devices. These research ensures the projector Completed the process from scratch。...
