Patent ID: 7656475

Claim:
A liquid crystal display (LCD) module, comprising: a backlight module having at least one illumination device for emitting at least a first color light, a second color light, and a third color light, wherein the wavelength of the second color light is between 520 nanometers (nm) and 540 nm, wherein the first color light has a wavelength less than the wavelength of the second color light, wherein the illumination device includes at least a first light emitting diode (LED), a second LED, and a third LED for emitting, respectively, the first color light, the second color light, and the third color light; and an LCD panel to display an image with the first color light, the second color light, and the third color light as light sources, the LCD panel comprising: a color filter having at least a first filtering layer, a second filtering layer, and a third filtering layer, wherein the first filtering layer is suitable for filtering the first color light, the second filtering layer is suitable for filtering the second color light, and the third filtering layer is suitable for filtering the third color light; and a liquid crystal layer disposed next to the color filter, a peak value of a transmission spectrum of the second filtering layer being provided between 520 nm and 540 nm, and a full width at half maximum (FWHM) of the transmission spectrum of the second filtering layer being between 90 nm and 120 nm, wherein a FWHM of a transmission spectrum of the first filtering layer extends from a first wavelength to a second wavelength larger than the first wavelength, and wherein the transmission spectrum of the first filtering layer does not overlap an emission spectrum of the second LED at the second wavelength.
