A METHOD FOR TESTING A LIGHT-EMITTING PANEL AND THE COMPONENTS THEREIN

摘要

A process for in-line testing and control of the manufacture of a display panel having a plurality of light-emitting micro-components sandwiched between two substrates is disclosed. The preferred process includes a step (900) of forming micro-capsules containing a gas capable of ionization when a sufficiently large voltage is supplied across the micro-component via at least two electrodes, a step (910) of forming a panel having at least one electrode for ionization of the gas and plurality of sockets for receiving the micro-capsules, a micro-component placement process (930), a process (940) of aligning a second substrate which may have another electrode placed thereon, and a dicing process (950). Another process (905) to dope or coat the micro-components with an emission enhancement material such as low affinity material, conductive, reflective and/or luminescent material, e.g., magnesium oxide, gold, aluminum, and/or phosphor coatings, may also be provided. The panels are preferably tested, such as for size, shape, position, material properties, or electric function after each process and the data stored and subsequently analyzed to determine necessary modifications of the process and/or product.
