Abstract
A radiation-emitting panel such as for back lighting a display has three transparent glass plates sealed together around their edges to form two gas-discharge volumes. The plates are supported within their edges by two identical arrays of pillars formed integrally from the plates. The lower surface of the lower plate is profiled with inverted frusto-pyramids and coated with a reflecting layer. Electrodes normally cause discharge within the upper volume, and the emission of light. Electrodes can be used to excite the lower volume, such as on failure of the upper volume, the reflector acting to reflect light preferentially into the pillars.
