<p>To manufacture display systems using light emitting diodes (LEDs) in large quantities at low cost, a plurality of LED layers forming pixels are deposited or printed on a substrate in bulk using thin film technology. Each display system includes a substrate; a first electrode unit formed on the substrate in a predetermined pattern; a LED layer comprising a P-type layer, which is formed on the surface of the first electrode unit in a predetermined pattern to be electrically connected to the first electrode unit, and a N-type layer deposited on the P-type layer; a transparent insulation layer formed on the surface of the substrate to be insulated from the first electrode unit by an insulation layer and to have a via-hole corresponding to the LED layer; and a second electrode unit electrically connected to the N-type layer of the LED layer.</p> |
