Claim:
1. An organic light-emitting diode (OLED) apparatus, comprising: at least one OLED illumination module; a driver, electrically connected to the OLED illumination module and configured to adjust voltage applied to the OLED illumination module, so as to change a correlated color temperature (CCT) of light emitted by the OLED illumination module; an optical sensor, configured to sense the light emitted by the OLED illumination module; a controller, configured to receive a feedback signal from then optical sensor so as to adjust a light intensity and the CCT of the OLED illumination module, wherein the light intensity and the CCT of the OLED illumination module is adjusted by adjusting the voltage and a duty cycle of a pulse wavelength modulation (PWM) to the OLED illumination module; and a storage, configured to store photoelectric parameter data of the OLED illumination module, the controller is configured to adjust the CCT and the light intensity of the OLED illumination module to target values according to the photoelectric parameter data, the photoelectric parameter data includes a relationship between at least two of voltage applied to the OLED illumination module, the CCT of the OLED illumination module, current applied to the OLED illumination module, and the light intensity of the OLED illumination module, wherein the photoelectric parameter data comprises a relationship at two end points of the voltage applied to the OLED illumination module or comprises a relationship in a table form having three or more voltages applied to the OLED illumination module.
