摘要： An information display apparatus includes a matrix of thin-film light-emitting diodes (LEDs) disposed on a transparent substrate. The thin-film LEDs are epitaxially grown on a semiconductor substrate, then transferred in strips to the transparent substrate, anchored by intermolecular forces, and separated into individual LEDs by photolithography and etching. The anodes and cathodes of the thin-film LEDs are connected to anode and cathode driving circuits by a matrix of thin-film electrical paths formed on the transparent substrate. The matrix of LEDs and interconnections is dense enough to display images of high quality, and provides enough pixels for the display of useful text and graphics on even small information display devices.
