OLED Tandem OLED for controlling color coordinate and color temperature and method for controlling color coordinate and color temperature thereof

摘要

The present invention relates to a tandem OLED device capable of adjusting color coordinates and color temperature, and a method of adjusting a color coordinate and a color temperature of the OLED device. More particularly, the present invention relates to a tandem OLED device capable of adjusting color coordinates and color temperature variations, OLED devices having a tandem structure and a method of adjusting color coordinates and color temperatures thereof.According to the OLED device of the tandem structure capable of adjusting the color coordinates and the color temperature of the present invention, it is possible to control the color coordinates and the color temperature at any time through post-processing of temperature and voltage control after fabrication of the tandem structure OLED device. According to the method of controlling the color coordinates and color temperature of the tandem-structured OLED device of the present invention, liquid-state interface dipoles whose hole or electron injection characteristics are improved upon voltage application are manufactured by inserting into a tandem-type OLED device, The color coordinate and the color temperature of the tandem-structured OLED device can be controlled simply and precisely.;
