Realization of RGB colors from top‐emitting white OLED by electron beam patterning

“…Shadow masks are often used for OLED structuring, but their potential for higher resolutions is low. Color filters in combination with white OLED are applied to convert white light into RGB, which has the advantage that the patterning of the semiconducting organic layers is not necessary, however results in low efficiency . Therefore, we present a new promising concept for OLED patterning that enables high‐resolution displays without using shadow masks or color filters.…”
