Abstract
A running screen method is applied to remove hot spot speckle on projection screen by a laser display system with one DLP panel. We have commercially displayed a projection image from a DLP (720 Pi) display system using a minimized RGB high power laser source. Then we successfully obtained a high-quality image with low speckle contrast as if hot spot speckle are not recognized on the screen when both the rotating diffuser and the rotating screen by piezoelectric motor are used.
