Pico-projector

It’s a video projector, but a very small one that will sit in the palm of your hand or fit comfortably in your pocket.

It can be used as a portable business projector, but the small size of the displayed picture — claimed to be a maximum of 60in (150cm) wide in excellent viewing conditions — means it’s really designed as an entertainment product to enable people to view video from their laptops, phones, digital cameras, iPods and other personal devices.

The terminology hasn’t settled down yet and other terms for the device exist, including palmtop projector, palm projector and, the oldest one, pocket projector. Pico-projector first appeared around 2003 but products with that name have only recently reached a performance level that makes them attractive.
