ABSTRACT:
A cut filter is used in a backlight module or a display device and positioned over the light source to filter off a part of the light comprising an overlap of at least two of the red light, the green light, and the blue light. By filtering off the overlapping part of light emitted from the light source to obtain a purer primary color light, the display device equipped with a conventional color filter can attain an improved color gamut.
