PROJECTOR HAVING SAW TOOTH REFLECTING MIRROR

摘要

A projector having saw tooth reflecting mirror includes a display screen (55), a saw tooth reflecting mirror (54), and an optical machine (51). The saw tooth reflecting mirror (54) is opposite to the display screen (55), and the modulated light beam emitted from the optical machine (51) is reflected onto the display screen (55) via the saw tooth reflecting mirror (54). The depth of the projector can be reduced by using the saw tooth reflecting mirror (54).
