High-brightness oled display device, preparation method thereof and display apparatus

Abstract

Provided are a high-brightness OLED display device, a preparation method thereof and a display apparatus, which relates to the technical field of OLED display. The high-brightness OLED display device includes a substrate and an optical microcavity structure on the substrate, the optical microcavity structure includes an R optical microcavity area, a G optical microcavity area and a B optical microcavity area. A cavity length of the G optical microcavity area is greater than that of the B optical microcavity region and is smaller than that of the R optical microcavity area. The beneficial effects of the disclosure are that RGB pixels can independently emit corresponding spectrums without the help of CF, realizing colorization control of silicon-based products, improving light extraction efficiency and product yield.
