Original Abstract Submitted
A display system includes a light source emitting blue light including blue wavelength, and UV light including UV wavelength. A first multilayer optical film (MOF) is disposed between a display panel and a second MOF. Light conversion films receive and convert emitted blue light to green and red lights. At incident angles of less than 10 degrees, the first MOF transmits greater than 50% of light for the blue wavelength and reflects greater than 60% for green and red peak wavelengths. The second MOF transmits greater than 50% for blue, green and red peak wavelengths, and reflects greater than about 60% for the UV wavelength. At oblique incident angles, the first MOF reflects greater than 50% for the blue, green and red peak wavelengths, and the second MOF transmits greater than 50% for the blue, green and red peak wavelengths, and transmits greater than 60% for the UV wavelength.
