International Classification:

G01N 21/64

US Classification:

436172000, 073866000

Abstract:

An test cell is adapted for both making and testing samples. The cell includes a bottom plate and a top plate having concentric apertures defining a central test cavity. A post attached to the bottom plate closes off the bottom of the test cavity. A slide closes off the top of the test cavity. The top of the post is spaced slightly from the underside of the slide to define a test cavity of substantially uniform thickness. The test cavity is filled with phosphor suspended in uncured resin, closed, and the resin is cured. Once cured, the sample is stable, although delicate, and can be re-measured several times with reproducible results. The measurement takes place in the cell, using a thin film of oil for wetting surfaces.

Abstract:

A light shutter and an EL panel are sandwiched between two substrates, one of which includes a common front electrode. The common front electrode is electrically floating. Patterned rear electrodes, on either side of the EL panel, are capacitively coupled to each other by the common front electrode. The rear electrodes can be segmented and the segments addressed individually. Each substrate is coated with a layer of PDLC and the substrates are laminated by joining the layers of PDLC.
