ABSTRACT:
A hybrid tubeless process has been developed for creating a high vacuum spool-shaped glass frits plug to be used for low cost, high throughput manufacturing of flat panel display devices. This is accomplished by using a 3-port exhaust tube which allows high vacuum sealing of the FED with minimum contamination hence protects the device from early failure.
