Abstract
A method and device for correcting a color shift of an OLED display panel, and a display device are disclosed. The method includes: performing an ageing treatment on the monochromatic luminescent devices in the OLED display panel; performing a luminescent lifetime attenuation test on the monochromatic luminescent devices after the ageing treatment respectively, and obtaining corresponding luminescent lifetime attenuation rates of the monochromatic luminescent devices; and performing an ageing treatment on the monochromatic luminescent device with rapidest luminescent lifetime attenuation rate again when differences between the luminescent lifetime attenuation rates of the monochromatic luminescent devices are greater than a preset threshold, until differences between the luminescent lifetime attenuation rates of the monochromatic luminescent devices are less than the preset threshold. The method effectively corrects the color shift phenomenon of display images of an OLED display product after long-term use.
