Laser‐induced thermal imaging (LITI) has been used to pattern polymeric light‐emitting devices (see Figure). Most commercial light‐emitting polymers (LEPs) are not suitable for LITI because of strong cohesion within the LEP layer. To reduce this and achieve excellent image quality, transfer layers based on blends of LEPs and inert polymers were used. The introduction of amorphous hole‐transporting materials also enhanced the brightness of the devices.
