Abstract
An OLED panel, apparatus, fingerprint identification method and device are provided in the field of display technology. The OLED panel includes an OLED pixel array comprising a plurality of OLED sub-pixels, and a photoelectric detection circuitry comprising a plurality of photoelectric detectors. The plurality of photoelectric detectors are respectively disposed between the plurality of OLED sub-pixels. At least one of the plurality of photoelectric detectors is configured to detect light rays whose wavelength ranges are outside of wavelength ranges of light rays emitted from the OLED sub-pixels adjacent to the photoelectric detector. The present disclosure may perform the fingerprint identification only with the display area of the OLED panel, such that the occupancy area of the screen on the OLED panel is increased, thereby increasing the screen ratio and improving the display performance.
