Title:
有機発光ダイオードカラーディスプレイ
Document Type and Number:
Japanese Patent JP4387460
Kind Code:
B2
Abstract:
A multi-color electroluminescent display has a plurality of discrete, laterally spaced areas of light emitting material formed over respective groups of first and second electrode regions. The light emissive material over each group is capable of emitting radiation of a different color. The multi-colored device is formed by a sequence of steps where each emitting layer is deposited as. a precursor which is susceptible to patterning and which is then converted into its polymer which is not susceptible to subsequent patterning steps. This allows a second color to be deposited on top of a first color, the second color being patterned while avoiding damage to the first color below it.
