Abstract
A multi-purpose light source comprising a laterally transmitting TFEL device (1,2a,2b,4) with a means to de-couple the intense lateral transmission via reflecting microstructures (11) is formed onto substrates in which, in the preferred embodiment, there is pre-fabricated addressing/drive circuitry (36 through 42). Such light sources are applicable to displays, particularly small area high resolution displays, and to linear imaging arrays, such as in electrophotographic printers.
