Pixel arrangement mode sharing blue light light emitting layer and organic electroluminescent device
Disclosed is a pixel arrangement with a shared blue light emitting layer (7), comprising m rows and n columns of first pixel units, the first pixel units are blue light sub-pixels (B), m is a non-zero natural number, n is a natural number larger than or equal to 2, wherein, two columns of second pixel units are arranged between neighboring first pixel units, each of the second pixel units comprises a red light sub-pixel (R), a green light sub-pixel (G) and a yellow light sub-pixel (Y) that are arranged in a juxtaposed manner. By properly modifying the pixel arrangement of the device configuration, light emitting in four colors can be achieved by using only two or less sets of low precision masks in the preparation process, so that the resolution is increased with reduced cost, and as compared to conventional pixel arrangement, the PPI can be doubled, reaching 600 PPI.
