Abstract
A photo-radiation source for the selective polymerization of photo-radiation-curable organic material. In a first embodiment, a first electrode is provided with a second electrode disposed adjacent to the first electrode, and defining a gap therebetween. A photo-radiation emission layer is disposed in the gap. The photo-radiation emission layer includes a charge-transport matrix material and an emissive particulate dispersed within the charge-transport matrix material. The emissive particulate receives electrical energy through the charge-transport matrix material applied as a voltage to the first electrode and the second electrode photo-radiation. The emissive particulate generates photo-radiation in response to the applied voltage. This photo-radiation is effective for the selective polymerization of photo-radiation curable organic material. In a second embodiment, a plurality of light emitting diode chips generate a photo-radiation spectrum effective for the selective polymerization of photo-radiation-curable organic material. Each chip has an anode and a cathode. A first electrode is in contact with each anode of the respective light emitting diode chips. A second electrode is in contact with each cathode of the respective light emitting diode chips. At least one of the first electrode and the second electrode comprises a transparent conductor. The plurality of chips are permanently fixed in a formation by being squeezed between the first electrode and the second electrode without the use of solder or wiring bonding. The plurality of chips can be permanently fixed in a formation by being adhered to at least one of the first electrode and the second electrode using a conductive adhesive. In accordance with this embodiment of the invention, ultra-high chip packing density is obtained without the need for solder or wiring bonding each individual chip.
