摘要： There is provided a composition for the liquid deposition of organic active materials. In the composition the organic active material is dispersed in a liquid medium. The liquid medium is made up of 5-35 % by weight of a first liquid having a boiling point greater than 160°C and 65-95 % by weight of a second liquid having a boiling point less than 130°C.

摘要： There is provided a process for making a multicolor organic light-emitting diode. The diode has a plurality of first subpixel areas (141) and a plurality of second subpixel areas (142). In the process, a patterned anode (110) is formed on a substrate and a non-patterned continuous hole injection layer (120) is formed over the anode. There is substantially no crosstalk observable between the first subpixels and the second subpixels. There is also provided the above process with the additional steps of forming a non-patterned continuous primer layer (130) over the hole injection layer, depositing a first electroluminescent material (141) from a first liquid composition in the first subpixel areas, depositing a second electroluminescent material (142) from a second liquid composition in the second subpixel areas, and depositing a cathode (160). The first and second electroluminescent materials emit light of different colors.
