Patent ID: 8102602

Claim:
A display, comprising: a white light-emitting diode (WLED), for emitting light having wavelength of λ i or λ j , having an emission spectrum BL(λ i or λ j ); and a color filter corresponding to the WLED and comprising a plurality of red, green and blue color resists, the color filter having a transmission spectrum CF(λ i or λ j ); wherein the emission spectrum BL(λ i or λ j ) and the transmission spectrum CF(λ i or λ j ) have specific relations therebetween, as follows: Y (λ i )= CF (λ i )× BL (λ i ), λ i =λ 1 ; MAX(λ j )=MAX[ CF (λ j )× BL (λ j )], λ j =λ 2 ; 0.20≦ Y (λ 1 )/MAX((λ 2 )≦1; wherein the wavelength λ 1 ranges between 590 nm and 600 nm, Y(λ 1 ) is a product of the transmission spectrum CF(λ 1 ) and the emission spectrum BL(λ 1 ), MAX(λ 2 ) is a maximum of the product of the transmission spectrum CF(λ 2 ) and the emission spectrum BL(λ 2 ).
