<p>An organic light emitting diode device being patterned into a plurality of independently addressable domains (11, 12) is disclosed. The light emitting layer (4) is of a first thickness (41) in a first domain (11) of the device and of a second thickness (42) in a second domain (12) of the device, such that when a voltage, that is sufficient to cause light to emit from said first domain (11) and said second domain (12), is applied over said light emitting layer (4), 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.</p> |
