A novel white light source based on RGB LED

Digital light processing(DLP) technology is a key branch of projection display,and the technology based on light emitting diode(LED) is an important development direction of DLP technology.A novel fabrication of LED is proposed according to the DLP projection application.A LED mixed white light source suiting for DLP micro-projector is achieved by optimization and artificial calculation.The light flux of the DLP micro-projector used for the LED mixed light is increased.
