Chip Can Project Video the Size of a Grain of Sand

A chip has been developed that can project video on a scale as small as a grain of sand. Originally designed for steering lasers in quantum computers, this MEMS array technology has found new applications in image projection. Researchers have demonstrated its capabilities by projecting the Mona Lisa using a long split-electrode device. This innovation could have implications for various fields, including semiconductors, biomedical imaging, and consumer electronics.
