Method for testing a light-emitting panel and the components therein
First Claim
1. A method for inline testing a plurality of light-emitting panels, comprising the steps of:
- manufacturing the plurality of light-emitting panels in a web fabrication process, the web fabrication process comprising a plurality of process steps and a plurality of component parts, wherein the plurality of process steps are performed a plurality of times to manufacture the plurality of light-emitting panels;
testing a portion of one or more light-emitting panels after at least one process step of the plurality of process steps is performed at least one time;
processing data from the testing to produce at least one result;
analyzing the at least one result to determine whether the at least one result is within a specific target range; and
adjusting the at least one process step or at least one component part of the plurality of component parts if the at least one result is not within the specific target range.

Abstract
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. A method of testing a light-emitting panel and the component parts therein is also disclosed, which uses a web fabrication process to manufacturing light-emitting panels combined with inline testing after the various process steps of the manufacturing process to produce result which are used to adjust the various process steps and component parts.

23. A method for forming a light-emitting panel, comprising the steps of:
-
providing a first substrate;
forming a plurality of cavities on or within the first substrate;
placing at least one micro-component in each cavity;
providing a second substrate opposed to the first substrate such that the at least one micro-component is sandwiched between the first substrate and the second substrate;
disposing at least two electrodes so that voltage supplied to the at least two electrodes causes one or more micro-components to emit radiation; and
inline testing at least one of the first substrate, at least one cavity of the plurality of cavities, the at least one micro-component, at least one electrode of the at least two electrodes, and the second substrate. - View Dependent Claims (24, 25, 26, 27)
