Abstract
A composite film for a quantum dot—organic light emitting diode (QD-OLED) display panel of an information handling system includes a polarizer film, a quarter wavelength retarder film, and a reflective polarizer film. The polarizer film reduces ambient light reflections within the QD-OLED display panel. The quarter wavelength retarder film is in physical communication with the polarizer film. The quarter wavelength retarder film combines with the polarizer film to reduce the ambient light reflections. The reduction of the ambient light reflections increases a contrast ratio for the QD-OLED display panel. The reflective polarizer film is in physical communication with the quarter wavelength retarder film. The reflective polarizer film increases a luminance of the QD-OLED display panel to a first value that is greater than a second value of the luminance created by the polarizer film and the quarter wavelength retarder film.
