Abstract
The laser-induced thermal imaging (LITI) process was found to be well suited for patterning any type of electroluminescent spin-coatable materials. The use of optically and electronically inert polymers such as polysterene (PS), poly(methyl methacrylate) (PMMA), poly(acenaphtylene) (PANa), etc., in light emitting polymer (LEP) blends was used in order to improve LITI pattern quality. In addition, amorphous hole transport materials (HTMs) were introduced to reduce device operating voltage. As a result, improved bright blue light-emitting patterned polymer light-emitting devices (PLEDs) was obtained.
