| titleOfInvention | Backlighting device for the display screen of a television or mobile phone |
| abstract | A backlight device (10) for a display screen (1) comprises a first light source (12) adapted to emit light having a peak wavelength between 600 and 630 nm; a second light source (14) adapted to emit light having a peak wavelength between 510 and 530 nm and a third light source (16) adapted to emit light having a peak wavelength between 440 and 460 nm. The spectral power distribution of the backlight results in an enhanced visual acuity and colour perception by better segregating the emission peaks (113, 115, 117) of the light sources and arranging their peak wavelengths at values which particularly suit the spectral sensitivity of the eye. Not only is the perceived resolution of the display screen increased but also the perceived brightness is improved allowing energy savings to be made. |
