Abstract

In this paper, we design a high power and small volume laser projector using the red laser diode, green laser diode, blue laser diode and green fluorescence as light source, which could improve the performance of the projector significantly with longer lifetime than lamps, higher reliability, and larger color gamut. According to the requirement of CIE Standard Illuminant D65 and light output, the power of red laser diode, green laser diode, blue laser diode and green fluorescence were calculated. The energy efficiency of four base-color optical path was also analyzed. It could be concluded that the blue laser and red laser have higher power requirements.
