摘要: An apparatus has a light modulator for emitting first-order diffracted beam to scan screen two-dimensionally and zero-order which is deflected projected onto the screen. The effectively utilized, projection-type display capable of displaying new image pattern in moving character drawn with single stroke are displayed an overlapping manner.
