Patent ID: 8772767

Claim:
A process for making an OLED luminaire, comprising: providing a substrate having a first patterned electrode thereon; depositing a first liquid composition in a first pixellated pattern to form a first deposited composition, the first liquid composition comprising a first electroluminescent material in a first liquid medium, said first electroluminescent material having a first emission color; depositing a second liquid composition in a second pixellated pattern which is laterally spaced from the first pixellated pattern to form a second deposited composition, the second liquid composition comprising a second electroluminescent material in a second liquid medium, said second electroluminescent material having a second emission color; depositing a third liquid composition in a third pixellated pattern which is laterally spaced from the first and second pixellated patterns to form a third deposited composition, the third liquid composition comprising a third electroluminescent material in a third liquid medium, said third electroluminescent material having a third emission color; drying the deposited compositions to form pluralities of pixels; and forming a second electrode over all the pixels; wherein one of the emission colors is blue, one of the emission colors is green, and one of the emission colors is red-orange; wherein the electroluminescent material with blue emission color has Formula I wherein: R 14 , R 15 , R 16 and R 17 are the same or different and are selected from the group consisting of H, D, and alkyl, where R 14 and R 15 groups or R 16 and R 17 groups may be joined together to form a 5- or 6-membered aliphatic ring; R 18 and R 19 are the same or different and are selected from the group consisting of D, alkyl groups, silyl groups, m-phenyl, o-phenyl, p-phenyl, m-N-carbazolyl, and p-N-carbazolyl; R 20 is the same or different at each occurrence and is selected from the group consisting of D, alkyl groups, silyl groups, phenyl, and biphenyl, or two adjacent R 20 groups can join together to form a naphthyl or fluorenyl group; a and b are the same or different and are an integer from 0-10; c and d are the same or different and are an integer from 1-5; f, g, h, and i, are the same or different at each occurrence and are an integer from 0-4; and e and j are the same or different at each occurrence and are an integer from 0-5.
