A thin-film electroluminescent (TFEL) display panel and method of fabricating a TFEL display are disclosed. The present invention relates to a TFEL display panel shielded by a pair of glass substrates with a protective material disposed therebetween wherein a metal washer is permanently bonded over the substrate oil fill orifices(s) and interfaces the cover glass. This metal washer is prepared in advance by pretinning with a solder to ease reflow after backfill process is complete. This solder provides the seal medium to close the backfill orifice. One of the advantages of using a soldered hole seal according to the present invention is that oil contamination becomes minimized. The backfill hole sealing is accomplished quickly in dry atmosphere without the presence of adhesives of flammable solvents.

Thin film flat panel displays and method of manufacture

A thin film electroluminescent display device energized with a rapid burst of pulses during a time less than the decay time of the phosphor yields substantially increased light output. Preferably, a burst of between two and forty pulses having a duration in the range between 5 and 20 microseconds and having alternating polarities is applied to the device. The pulse burst technique is advantageously applied to a dot matrix type EL display panel operating at a 60 Hz refresh rate. For a 512.times.256 element display panel, each row is addressed for approximately 65 microseconds, and four pulses of about 12-15 microseconds each are applied to the EL pixels during each row address time. The pulse burst technique provides increased brightness while minimizing the retained image problem.

Pulse burst panel drive for electroluminescent displays

An electrical connecting device for use with a multiple layered circuit-containing device wherein at least two layers of the multiple layered circuit-containing device each contain a circuit including a plurality of circuit contacts to be electrically connected by the electrical connecting device. The electrical connecting device includes an upper longitudinal peripheral surface joined to a lower longitudinal peripheral surface by an intermediate longitudinal surface to form an elongated member which has a Z-shaped configuration in cross section and is formed from a plurality of Z-shaped connectors shaped from each other in a predetermined amount to effect a moire pattern when superimposed relative to the circuit contacts of at least one of the layers.
