1 jan 1950 ano - LCD PROJECTOR

Descrição:

It got its start pre-WWII, when the Army used it for training soliders. Then, the police got interested, because it made identifying suspects easier. You could project images across a screen. By the late 1950s and early 1960s, overhead projectors made it into schools, and the interactive classroom was born.
