HIGH COLOR SATURATION DISPLAY AND COLOR ADJUSTING METHOD THEREOF

摘要

A display device and a color adjusting method are provided. The display device includes a backlight source and color resists disposed above the backlight source for filtering the light from the backlight source. An intensity spectrum of the backlight source has several segments which includes a first segment having a peak value existing at a wavelength between 515 nm and 535 nm. The color resists have a peak transmittance, which is smaller than 75%, existing at a wavelength between 520 nm and 540 nm. In addition, the transmittance of the color resists is smaller than 0.05% at the wavelength of 730 nm. Since the wavelength ranges in the range mentioned above are correlated, the color resists are capable of adjusting the light from the backlight source to enhance the color saturation.
