Title:
OLED DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND OLED DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/115126
Kind Code:
A1
Abstract:
An OLED display panel, comprising a display area. The display area comprises a red sub-pixel area. The OLED display panel comprises: a substrate, a light-emitting device, and a color resist layer. The light-emitting device is provided on the substrate and located in the red sub-pixel area. The light-emitting device has a microcavity structure, and the range of the length of the microcavity of the light-emitting device is 100-500 nm. The light-emitting device is configured to emit red light. The color resist layer is provided in the red sub-pixel area and located at a light emitting side of the light-emitting device. The color resist layer is configured to enable the transmittance of light rays having a wavelength of 585 nm or more to be greater than the transmittance of light rays having a wavelength of 585 nm or less.
