A LINE SCANNING PROJECTION DISPLAY SYSTEM COMPRISING A DOUBLE PIXEL ARRAY LIGHT MODULATOR

摘要

A method and system is disclosed providing improved response time in a Tuneable Diffraction Grating (TDG) component based line scanning projection system by alternating incident light between at least two parallel pixel arrays in said TDG component and said incident light. By synchronously controlling the movement of the incident light between the at least two pixel arrays according to which of said two pixel arrays comprising a steady state of an image line to be displayed while the other pixel array is being loaded, the "on" time of a pixel is prolonged to significantly improving the light efficiency of the display system.
