The history of creation and the principle of the action of multimedia projectors can be found in the review devoted to the basic projection technologies.

Classification of projectors. By function, projectors can be divided into three main groups:
⦁ projectors for home cinema, game projectors (category Home Cinema),
⦁ projectors for the entertainment industry (for movie theaters, etc.)
⦁ projectors for business and education.

The first group is focused primarily on the reproduction of dynamic content (“live” video), the second and third groups are usually intended for both dynamic and static content. In a separate group, we can distinguish subminiature projectors weighing less than 0.5 kg (see below).

Separately, it should be noted the projectors that support the transfer of information in 3D. Recently, such projectors have found wide distribution not only in the film industry, but also in educational institutions, museums, etc. Also, stereoscopic applications are increasingly used in business processes, modeling, etc.
