Smartphones with inbuilt projector circuit

  1. Sep 27, 2018 #1
    Is it feasible to design and construct State of the art Smartphones with inbuilt mini projector device functionality ?

    As we know there is a inbuilt torch feature in the Smartphones but has limited functionality.

    If not, Why?

    Thanks & Regards,

    The short answer is no.
    There's an obvious reason -- can you say what that is?

    And beyond the simple answer, there are much better ways to do projection of the information from a smartphone. I can think of two right away -- can you guess what those probably are? (the first is obvious, the second is more subtle) :smile:

    The amount of power to produce enough light to project an image is beyond the batter capacity of a device the size of a cell phone.

    You would also have to deal with the heat.

    Can't we increase the Battery capacity required for the projector circuit?

    Will the Battery requirements be huge fir the Smartphone to work as a projector device?
