Abstract

A double-sided emissive organic display device includes a carrier, a control element layer structure above the carrier, a plurality of first organic light emitting components, which are formed above the carrier, which are electrically connected to the control element layer structure and which are driven by means of the control element layer structure during the operation of the double-sided emissive organic display device and emit first light substantially in a direction toward the carrier, and a plurality of second organic light emitting components, which are formed above the control element layer structure and which are electrically connected to the control element layer structure and which are driven by means of the control element layer structure during the operation of the double-sided emissive organic display device and emit second light substantially in a direction away from the carrier.

First claim

What is claimed is:

1. A double-sided emissive organic display device, comprising:
a single carrier;
a plurality of first organic light emitting components form first pixels, which are formed above the single carrier, which are electrically connected to a single control element layer and which are driven by the single control element layer during the operation of the double-sided emissive organic display device and emit first light substantially in a direction toward the single carrier;
the single control element layer above the plurality of first organic light emitting components; and
a plurality of second organic light emitting components form second pixels, which are formed above the single control element layer and which are electrically connected to the single control element layer and which are driven by the single control element layer during the operation of the double-sided emissive organic display device and emit second light substantially in a direction away from the single carrier,
wherein each of the first and second organic light emitting components includes, a first electrode, an organic functional layer structure above the first electrode, and
a second electrode above the organic functional layer structure, and
wherein the control element layer structure includes at least one active component;
wherein the first pixels and the second pixels are formed such that they form a lateral overlap region and the second pixels are larger in area than the first pixels.

2. The double-sided emissive organic display device of claim 1 ,
wherein the first organic light emitting components are formed in a manner offset with respect to the second organic light emitting components in a vertical direction.

3. The double-sided emissive organic display device of claim 1 ,
wherein the first pixels are formed by in each case at least two adjacent first organic light emitting components, and wherein the second pixels are formed by in each case at least two adjacent second organic light emitting components.

4. The double-sided emissive organic display device of claim 1 ,
wherein the first organic light emitting components of one of the first pixels are formed in a manner offset with respect to the second organic light emitting components of one of the second pixels, which forms a lateral overlap region with the corresponding first pixel in a lateral direction in such a way that in each case one of the first organic light emitting components of the corresponding first pixel forms a lateral overlap region with one of the second organic light emitting components of the corresponding second pixel.

5. The double-sided emissive organic display device of claim 1 ,
wherein the individual first organic light emitting components in each case have a different size than the individual second organic light emitting components in a lateral direction.

6. The double-sided emissive organic display device of claim 1 ,
wherein the single control element layer comprises a plurality of sense lines and a plurality of signal lines, which intersect one another and which are electrically connected to the first organic light emitting components and to the second organic light emitting components for the purpose of driving the pixels, wherein the sense lines or the signal lines are electrically connected in each case to a plurality of the first organic light emitting components and to a plurality of the second organic light emitting components, such that the first organic light emitting components and second organic light emitting components connected to one of the sense lines or to one of the signal lines are drivable by means of the same corresponding sense line or signal line.
