LASER PROJECTION DISPLAY AND METHOD FOR ALIGNING COLOR OF THE SAME

摘要

The present invention relates to a laser projection display which can sense a misalignment between colors and automatically correct the same, and a color alignment method thereof. The laser projection display comprises: a light source portion which emits laser light; a light separation portion which separates the laser light into first light and second light; a light scanner which realizes an image by radiating the separated first light onto a screen; a sensing portion which senses the separated second light; and an alignment correction portion which calculates a location change of the second light sensed from the sensing portion by time, and corrects an color alignment to correspond to a calculated location change value. A distance between a light emission side of the light separation portion and a light incidence side of the light scanner can be equal to a distance between the light emission side of the light separation portion and a light incident side of the sensing portion.
