FULL-COLOR LIGHT EMITTING DEVICE

摘要

Light emitting devices including at least one pixel (100) comprising a first light emitting stack (150) and a second light emitting stack (160) placed side-by-side. The first and second light emitting stacks each comprise a first OLED (102) and a second OLED (104) over the first OLED. The first light emitting stack further includes a downconversion layer (106) under the first OLED. Together, the first and second stacks are capable of emitting any visible color of light.
