| titleOfInvention | Ferroelectric flat panel displays |
| abstract | A thin film of ferroelectric layered superlattice material in a flat panel display device is energized to selectively influence the display image. In one embodiment, a voltage pulse causes the layered superlattice material to emit electrons that impinge upon a phosphor, causing the phosphor to emit light. In another embodiment, an electric potential creates a remanent polarization in the layered superlattice material, which exerts an electric field in liquid crystal layer, thereby influencing the transmissivity of light through the liquid crystal. The layered superlattice material is a metal oxide formed using an inventive liquid precursor containing an alkoxycarbolyxate. The thin film thickness is preferably in the range of 50-140 nm, so that polarizability and transparency of the thin film is enhanced. A display element may comprise a varistor device to prevent cross-talk between pixels and to enable sudden polarization switching. A functional gradient in the ferroelectric thin film enhances electron emission. Two ferroelectric elements, one on either side of the phosphor may be used to enhance luminescence. A phosphor can be sandwiched between a dielectric and a ferroelectric layer to enhance emission. |
