OLED-DEVICE WITH PATTERNED LAYER THICKNESS

摘要

A light emitting device comprising a substrate (1) supporting a plurality of layers (2, 3, 5), of which two sandwich a light emitting layer (4), said device being patterned into a plurality of independently addressable domains (11, 12) is disclosed. At least one of said layers (2, 3, 5) is of a first thickness in said first domain and of a second thickness in said second domain, such that when a voltage, that is sufficient to cause light to emit from said light emitting layer (4), is applied over said light emitting layer, light of a first color point is emitted by said first domain (11) of said device and light of a second color point is emitted by said second domain (12) of said device.
