ABSTRACT:
Light emitting devices including at least one pixel comprising a first light emitting stack and a second light emitting stack placed side-by-side. The first and second light emitting stacks each comprise a first OLED and a second OLED over the first OLED. The first light emitting stack further includes a downconversion layer under the first OLED. Together, the first and second stacks are capable of emitting any visible color of light.
