Abstract:
1. A method for manufacturing an organic light emitting diode display having a matrix of pixel areas that includes at least first pixel areas and second pixel areas, the method comprising: depositing a photoresist across the first pixel areas and the second pixel areas; patterning the photoresist into a patterned photoresist by stripping away first portions of the photoresist in the first pixel areas while keeping second portions of the photoresist in the second pixel areas; depositing an organic emission layer across the first pixel areas and the second pixel areas, the organic emission layer deposited over the patterned photoresist in the second pixel areas; depositing an electron transport layer across the first pixel areas and the second pixel areas over the organic emission layer; and removing portions of the organic emission layer and the electron transport layer in the second pixel areas by stripping away the second portions of the photoresist while keeping portions of the organic emission layer and the electron transport layer in the first pixel areas.
