What is projector phones?

Projector phones are smartphones that come with a built-in projector. They allow users to project images, videos, presentations, and other content onto a larger screen or surface. Projector phones work by using micro-display technology to project the image onto a surface from the back of the phone.

The image size and resolution may vary depending on the phone's specifications. Most projector phones have a brightness of at least 50-100 lumens, which is bright enough to allow projection in a dark room.

These phones can be useful for business presentations, entertainment, and educational purposes. Some popular projector phones include the Samsung Galaxy Beam, Lenovo Smart Cast, and ZTE SPro 2.

However, projector phones may come with some disadvantages, such as short battery life due to the additional power required to run the projector. Additionally, the projection quality may not be as sharp as on a dedicated projector. Finally, the added feature of a projector can make the phone more expensive and bulkier than a traditional smartphone.
