Patent ID: 7333165

Claim:
A liquid-crystal display apparatus comprising: a liquid-crystal panel having a color filter; a plurality of first white light sources for irradiating first white light to said liquid-crystal panel; a plurality of second white light sources for irradiating second white light different from the first white light to said liquid-crystal panel; illuminance detecting means for detecting ambient illuminance of said liquid-crystal panel to output a detected signal; and light source control means for switching said first and second light sources based on the detected signal from said illuminance detecting means; wherein the plurality of first and second white light sources are interposed in a backlight array and aligned to illuminate a back side of said liquid-crystal panel; wherein each first white light source includes a blue light-emitting diode, a yellow fluorescent material, and a first reflecting layer and each second white light source includes an arbitrary-color light-emitting diode, a mixed-color fluorescent material, and a second reflecting layer.
