Abstract
A method of testing a light-emitting panel and the component parts therein including an assembled web containing light-emitting micro-components is disclosed. The method utilizes radiometric measuring devices disposed throughout a continuous fabrication process. Qualities of the components are measured so that product defects or process deficiencies can be corrected or eliminated.
Claims19
A method for on-line testing micro-components within an assembled web during continuous manufacturing of the assembled web, the method comprising:
- passing at least a portion of the assembled web within a field of view of at least one radiometric output measuring device;
- exciting at least one selected micro-component disposed on the assembled web within the field of view to luminescence;
- detecting radiation emitted from the selected micro-component;
- analyzing the detected radiation;
- and
- processing of the assembled web in accordance with the analysis.
A method for on-line testing of a plurality of micro-components within an assembled web during a continuous manufacturing process of the assembled web, the method comprising:
- passing at least a portion of the assembled web within a field of view of a plurality of radiometric output measuring devices disposed at various locations throughout the continuous manufacturing process;
- exciting at least one selected micro-component disposed on the assembled web within the field of view to luminescence;
- detecting radiation emitted from the selected micro-component;
- analyzing the detected radiation;
- and
- disposing of the assembled web in accordance with the analysis.
