Abstract
The present invention relates to an active-matrix OLED display, comprising a plurality of OLED pixels, wherein each pixel itself comprises a stack of organic layers and each layer of the stack of organic layers can form a common semiconductor layer, wherein—at least a first OLED pixel and a second OLED pixel comprising—an anode layer, —a common cathode layer, —at least a stack of organic layers, comprising a plurality of semiconductor layers.
Claims32
An active-matrix OLED display, comprising a plurality of OLED pixels, wherein each pixel itself comprises a stack of organic layers, wherein
- at least a first OLED pixel and a second OLED pixel comprising
- an anode layer,
- a common cathode layer,
- at least a stack of organic layers, comprising
- a plurality of semiconductor layers, and the plurality of semiconductor layers comprising at least two or more common semiconductor layers, wherein the plurality of semiconductor layers comprising
- at least a common first semiconductor layer that is a common hole injection layer, wherein the common hole injection layer comprises a hole injection material, and wherein the common hole injection layer extends over all pixels of the plurality of pixels or extends over at least two pixels of the plurality of pixels in the OLED display,
- at least a common second semiconductor layer,
- at least one emission layer, which is optional a common emission layer, and wherein the common hole injection layer and the common second semiconductor layer have together a sheet resistance of ≥50 giga ohms per square.
