Essentially, a lamp, video source, and lens system.

Pico projectors, hence systems at mobile phone size (mostly Texas Instruments DLP but also other liquid crystal (LC) based systems) nowadays have three LEDs, a micromirror chip where the movie/video source is projected onto, and some optics (lenses/prisms).

In a laser projector, the LEDs are replaced by laser diodes and the optics is different. Mostly these systems provide brighter images and do virtually not need to be focussed.
