Patent ID: 7821195

Claim:
A display device, comprising: a backlight source with an intensity spectrum exhibiting a first peak range and a second peak range; and a plurality of color resists formed on the backlight source and configured to filter lights emitted form the backlight source to generate an output light, wherein a result of the color resists under a CIE standard illuminant C test is selected from one of combinations (a) and (b): (a) when a NTSC saturation of the output light is less than 60%, 0.125<By<0.172; 2.4( Bx− 0.151)+0.142 ≦By≦ 2.5( Bx− 0.139)+0.142; and 0.36 <RY/GY< 0.40, wherein (Bx, By) are coordinates of blue light obtained from the CIE standard illuminant C test, RY and GY are transmittances of red light and green light, respectively; (b) when the NTSC saturation of the output light is greater than 60%, 0.123<By<0.154; Gx<0.275; 0.594<Gy<0.620; and RY/BY> 1.06, wherein (Gx, Gy) are coordinates of green light obtained from the CIE standard illuminant C test, BY is a transmittance of blue light.
