1. A composite film for a quantum dot-organic light emitting diode (QD-OLED) display panel of an information handling system, the composite film comprising:
a polarizer film to reduce ambient light reflections within the QD-OLED display panel,
wherein the polarizer film includes:
a first base film; and
a patterned vertical alignment film in physical communication with the first base film;
a quarter wavelength retarder film in physical communication with the polarizer film, the quarter wavelength retarder film to combine with the polarizer film to reduce the ambient light reflections, wherein the reduction of the ambient light reflections increases a contrast ratio for the QD-OLED display panel; and
a reflective polarizer film in physical communication with the quarter wavelength retarder film, the reflective polarizer film to increase 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.
