projector phone
Mini projectors are standalone peripherals that are operated together with smartphones. They are also available as embedded devices, where they are embedded in the smartphones. They are thus an integral part of the smartphones and can be used directly for presentations or lectures.
Smartphones with built-in mini projectors or pico projectors that can also be used to make phone calls are called projector phones. The user of a projector phone has only one device with which he can make calls and project at the same time. Depending on the light intensity of the mini projector module, the projections can illuminate projection surfaces of about 1 m. The projections can be made on the phone. They have the advantage that they can be operated without additional connection cables and the presentations can be called up directly.
