Abstract
There is provided an organic light-emitting diode luminaire. The luminaire includes a patterned first electrode, a second electrode, and a light-emitting layer therebetween. The light-emitting layer includes a first plurality of pixels having a first emitted color; and a second plurality of pixels having a second emitted color, the second plurality of pixels being laterally spaced from the first plurality of pixels. In the luminaire the pixels have a pitch no greater than 200 microns. The additive mixing of all the emitted colors results in an overall emission of white light.

An organic light-emitting diode luminaire comprising a patterned first electrode, a second electrode, and a light-emitting layer therebetween, the light-emitting layer comprising:
- a first plurality of pixels having a first emitted color;
- a second plurality of pixels having a second emitted color, the second plurality of pixels being laterally spaced from the first plurality of pixels;
- wherein:
- the pixels have a pitch no greater than 200 microns;
- and
- the additive mixing of all the emitted colors results in an overall emission of white light.
A process for making an OLED luminaire, comprising:
- providing a substrate having a first patterned electrode thereon;
- depositing a first liquid composition in a first pixellated pattern to form a first deposited composition, the first liquid composition comprising a first light-emitting material in a first liquid medium,
- said first light-emitting material being capable of emitting a first color;
- drying the first deposited composition to form a first plurality of pixels;
- depositing a second liquid composition in a second pixellated pattern which is laterally spaced from the first pixellated pattern to form a second deposited composition, the second liquid composition comprising a second light-emitting material in a second liquid medium, said second light-emitting material being capable of emitting a second color;
- drying the second deposited composition to form a second plurality of pixels;
- and
- forming a second electrode over all the pixels.
