Light-emitting panel and a method for making
View Patent ↗An improved light-emitting panel having a plurality of micro-components sandwiched between two substrates is disclosed. Each micro-component contains a gas or gas-mixture capable of ionization when a sufficiently large voltage is supplied across the micro-component via at least two electrodes. An improved method of manufacturing a light-emitting panel is also disclosed, which uses a web fabrication process to manufacturing light-emitting displays as part of a high-speed, continuous inline process.
1. A web fabrication process for manufacturing a plurality of light-emitting panels, comprising:
forming a first substrate comprising a plurality of channels within the first substrate and at least one side surface including a plurality of substantially semi-circle openings to the plurality of channels; and
force-feeding a single micro-component through the plurality of channels via one of the plurality of substantially semi-circle openings of the side surface of the first substrate, the micro-component having a cylindrical shape, being not more than 300 microns in diameter across its minor axis, and emitting radiation when exposed to a trigger voltage.
2. The process of claim 1 , wherein each of the plurality of channels comprises at least one end at the side surface of the first substrate, and the process further comprises heating the micro-component to allow the micro-component to bend around the end of each channel.
3. The process of claim 1 , wherein the force-feeding comprises force-feeding a plurality of micro-components, each micro-component emitting a specific color of visible light when exposed to the trigger voltage.
4. The process of claim 1 , further comprising coating each channel with a specific color phosphor.
5. A web fabrication process for manufacturing a plurality of light-emitting panels, comprising:
forming a first substrate comprising a plurality of channels within the first substrate approximately equally spaced from one another in parallel and at least one side surface including a plurality of substantially semi-circle openings to the plurality of channels; and
force-feeding a single micro-component through the plurality of channels via one of the plurality of substantially semi-circle openings of the side surface of the first substrate, the micro-component having a cylindrical shape, the single micro-component being bent in a u-shape at multiple points so as to be woven through the plurality of channels in a continuous fashion; and
forming at least one electrode in contact with the single micro-component such that the single micro-component is capable of emitting radiation when the at least one electrode is exposed to a trigger voltage.
