Abstract
A dielectric display device includes a pair of substrates, at least one of which is transparent, spaced in parallel a constant distance apart, and facing each other. A dielectric display material is inserted between the pair of substrates. Further, a pair of electrodes, at least one of which includes a plurality of line (or scanning) electrodes, are disposed on the sides of the substrate facing the other substrate. Finally, a static erasing conductor is disposed extending peripherally along, and spaced a constant distance from, the ends of the electrodes for preventing intrusion of static electricity into electric lead lines.
Claims4
A dielectric display device comprising:
- a pair of substrates, at least one of which is transparent, spaced a distance apart, in parallel to each other;
- a dielectric display material inserted between said pair of substrates;
- signal and scanning electrodes, at least one of said signal and scanning electrodes including a plurality of electrodes disposed in parallel on one of said pair of substrates;
- a static erasing conductor disposed peripherally along at least one of said pair substrates, being initially connected to ends of each of said electrodes disposed in parallel to allow for release of static electricity from the electrodes through the connected static erasing conductor, and being subsequently separated by a laser and being maintained at a constant distance from ends of said electrodes disposed in parallel, to thereby shield the electrodes disposed in parallel from subsequent externally generated static electric effects.
A method of forming a dielectric display device comprising the steps of:
- (a) forming a pair of substrates, at least one of which is transparent, in parallel, spaced a constant distance apart;
- (b) inserting a dielectric display material between the pair of substrates;
- (c) disposing signal and scanning electrodes on the substrates, at least one of the signal and scanning electrodes including a plurality of electrodes disposed in parallel on one of the pair of substrates;
- (d) disposing a static erasing conductor peripherally along at least one of the pair of substrates;
- (e) connecting the static erasing conductor to ends of each of the electrodes disposed in parallel to allow for release of static electricity from the electrodes through the connected static erasing conductor;
- (f) separating the static erasing conductor from the ends of each of the electrodes disposed in parallel by a laser;
- and
- (g) maintaining the separated static erasing conductor, at a constant distance from the ends of each of the electrodes disposed in parallel, peripherally along at least one of the pair of substrates, to thereby shield the electrodes disposed in parallel from subsequent externally generated static electric effects.
