Pixel arrangement of organic blue light emitting layer and organic electroluminescent device

摘要

The present invention includes a first pixel unit of m rows and n columns, the first pixel unit is a blue light subpixel (B), m is a non-zero natural number, n is a natural number of 2 or more, and the adjacent first pixel unit Between the two rows of second pixel units is provided, each second pixel unit is a blue light emitting layer (7) comprising a red light sub-pixel (R), a green light sub-pixel (G) and a yellow light sub-pixel (Y) arranged in parallel It provides a pixel arrangement method. By changing the structure configuration method of the device, in the manufacturing process, four colors of light emission can be realized using a mask plate with a low precision of up to two sets, and the resolution is improved and the cost is reduced. By doubling, it can reach 600PPI.
