BLUE LIGHT COMPENSATION FILM, AND OLED DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/068394
Kind Code:
A1
Abstract:
A blue light compensation film (50), and OLED display device. The blue light compensation film (50) employs a blue-light upconversion luminescent material to absorb long-wavelength light having a wavelength greater than a blue-light wavelength and to excite blue light having a shorter wavelength, thus improving a color shift caused by a short service life of a blue electroluminescent material of a white-light OLED device, providing blue-light compensation to a white-light OLED device, and solving the problem of a common yellow color shift of conventional OLED display devices. The OLED display device comprises the blue light compensation film (50) to eliminate a color shift, thus providing superior display quality.
