Abstract:
An exemplary MLA unit for use in a projection device is disclosed. The projection device includes an LCD panel. The LCD panel includes a number of pixels each having an opening. The MLA unit includes a first MLA, and a second MLA. The first MLA includes a number of first micro lenses each configured for focusing incident light into the opening of a respective pixel of the LCD panel. The second MLA includes a number of second micro lenses each aligned with a respective first micro lens of the first MLA so as to form a micro lens system. The second MLA is movable so as to change the effective focal length of the lens systems.
