Abstract (en)

[origin: EP0518612A1] A portable computer (50) having a projection display (10) using a plurality of cold cathode field emission devices (30) formed on a single substrate (12) in rows and columns to produce images which are projected through a lens system (52) onto a remote flat surface (54). Memory and switching devices (39, 40) are formed on the same substrate (12) so the display (10) can be simply connected to any portable electronic device (50) and the size of the device (50) is independent of the display (10). <IMAGE>
