Abstract:
The present invention provides a blue light compensation film and an OLED display. The blue light compensation film of the present invention effectively absorbs blue light with wavelength longer than blue wavelength and excite blue light by using a blue light upconversion luminescent material, and effectively improves color shift white OLED device caused by short lifespan of blue electroluminescent material to achieve blue light compensation of the white OLED device and solve the of yellowing in traditional OLED display with age. The OLED display of the present invention comprises the blue light compensation film to avoid color shift problem and provides good display quality.
