PIXEL ARRANGEMENT MODE SHARING BLUE-LIGHT LIGHT-EMITTING LAYER AND ORGANIC ELECTROLUMINESCENT DEVICE

摘要

A pixel arrangement mode sharing a blue light light-emitting layer (7). The arrangement mode comprises m rows and n columns of first pixel units, where the first pixel unit is a blue-light sub-pixel (B), m is a nonzero natural number, and n is a natural number greater than or equal to 2. Two columns of second pixel units are disposed between neighboring first pixel units, and each second pixel unit comprises a red light sub-pixel (R), a green light sub-pixel (G) and a yellow light sub-pixel (Y) arranged side-by-side. The present invention modifies a structural arrangement mode of a device so as to enable the device to emit light in four colors, only needing two or less than two sets of low precision mask plates in a preparation process, improving resolution and reducing cost. Compared to a traditional arrangement mode, PPI can double, achieving 600 PPI.
