Wide-color gamut film, display apparatus with the wide-color gamut film, and method for manufacturing the film

Abstract

Disclosed are a wide-color gamut film and its applications. While the wide-color gamut film is manufactured, the method firstly confirms the type of the backlight. The film is designed to filter some specified frequency bands, especially the bands adjacent to the frequencies of red, green and blue lights. The parameters are referred to decide an overall thickness and an overall refractive index, and prepare a plurality of high-polymeric thin films. A wide-color gamut film is formed by assembling the thin films according to the configuration. The invention also relates to a display using the wide-color gamut film. The film is disposed between a panel module and a backlight module of the display. The film serves to reduce or filter out the light transmittance within the determined bands. The wide-color gamut film is provided for improving the crosstalk phenomenon among the frequency bands of the backlight.
