Abstract
A portable, electronic, desk-top information display device for office use in recording and selectively displaying information, comprising a keyboard the keys of which are operable to control the operation of electronic circuitry forming part of the device, and a stationary display panel on which the said electronic circuitry is adapted to produce a matrix array of illuminated dots of other discrete display items in a multiplicity of substantially equi-distant columns, with each dot being illuminated independently of all the others, so as to permit a plurality of letters, numbers or other symbols to be displayed simultaneously across the panel with the majority of such symbols having a width of at least two columns.
