Abstract
An organic light emitting device with selected electrical energy potential imposed across the organic luminous material.
Claims41
An organic light emitting device comprising:
- (a) a plurality of first electrodes;
- (b) a plurality of second electrodes at least partially intersecting said first plurality of said first electrodes;
- (c) an organic luminous element being coupled to at least one of said first electrodes and to at least one of said second electrodes at a location proximate where said at least one of said first electrodes and said at least one of said second electrodes intersect;
- and
- (d) a control mechanism suitable to illuminate said organic luminous element by providing electrical energy to said organic luminous element in a manner that said illumination from said organic luminous element is substantially uniform for a major portion of the duration that said electrical energy causes said illumination.

An organic light emitting device comprising:
- (a) a plurality of first electrodes;
- (b) a plurality of second electrodes, each of which at least partially intersects a plurality of said first electrodes;
- (c) respective organic luminous elements being coupled to respective ones of said first electrodes and to respective ones of said second electrodes at a location proximate where respective ones of said first electrodes and respective said respective ones of said second electrodes intersect;
- and
- (d) a control mechanism for causing at least one of said luminous elements to emit light by imposing a first electrical energy to a first one of said first electrodes while selectively providing electrical energy to selected ones of said plurality of second electrodes and simultaneously causing a plurality of said luminous elements associated with another one of said first electrodes to be free from emitting light by imposing a second electrical energy on said another first electrode in a manner that the charge initially imposed on opposing sides of said luminous elements free from emitting light are substantially equal.

An organic light emitting device comprising:
- (a) a plurality of first electrodes;
- (b) a plurality of second electrodes at least partially intersecting said first plurality of said first electrodes;
- (c) an organic luminous element being coupled to at least one of said first electrodes and to at least one of said second electrodes at a location proximate where said at least one of said first electrodes and said at least one of said second electrodes intersect;
- and
- (d) a control mechanism suitable to illuminate said organic luminous element by providing electrical energy to said organic luminous element in a manner that said illumination from said organic luminous element is free from any substantial undershoot and overshoot during initial said illumination.

An organic light emitting device comprising:
- (a) a plurality of first electrodes;
- (b) a plurality of second electrodes at least partially intersecting said first plurality of said first electrodes;
- (c) a first organic luminous element being coupled to at least one of said first electrodes and to at least one of said second electrodes at a location proximate where said at least one of said first electrodes and said at least one of said second electrode intersect;
- (d) a second organic luminous element being coupled to at least another one of said first electrodes and to at least one of said second electrodes at a location proximate where said at least another one of said first electrodes and said at least one of said second electrode intersect;
- (e) a control mechanism suitable to illuminate said first organic luminous element by providing electrical energy to said first organic luminous element in a manner that said first organic luminous element is illuminated illumination from said first organic luminous element is free from any substantial undershoot and overshoot during initial said illumination;
- and
- (f) said control mechanism suitable to simultaneously maintain said second organic luminous element from illumination by providing electrical energy to both sides of said second organic luminous element in in a manner that the charge on both sides of said second organic luminous element, substantially when said first organic luminous element is illuminated, is substantially equal.
4 more elements
An organic light emitting device comprising:
- (a) an organic luminous element interposed between a first electrode and a second electrode;
- (b) a control mechanism suitable to illuminate said organic luminous element by providing electrical energy to said organic luminous element in a manner that said illumination from said organic luminous element is substantially uniform during a major portion of said illumination.
