Abstract: The invention discloses a portable integrated electronic device for community learning, data transmission, entertainment and public governance which comprises a housing that accommodates a plurality of sub-assemblies. The sub-assemblies include a projector for projecting video and digital data into a predetermined ultra large size image over a surface external to the housing, a means for recording, reproducing and storing audio, video and/or digital data onto and/or from an external disk and an internal storage unit, a computational circuit for receiving and processing data input through an input device and adapted to be connected to a network and a television tuner card adapted to receive a plurality of television signal data. The sub-assemblies are in preconnected relationship with each other such that the sub-assemblies are operated by ON-OFF of a single button and the device becomes extremely compact, portable and easy to use.
