In recent years, the laser phosphor technology is becoming a mainstream one in the industry of projection display. In this paper, we first review the development of different light source technologies used in projectors. Thereafter, we review the evolution of our laser phosphor technology and then present its latest progress ‐ RGB laser phosphor.
As the defects in the LED chip is an important factor affecting the properties of high-power LEDs, a new measurement system is proposed which can get nonradiative recombination defect densities of a LED chip quantification ally, and a new method for evaluation of LED's performance is introduced which based on the relationship model between nonradiative recombination defect and LED's aging property...
