Backlight Module and Method of Manufacture Using Complementary Light Sources having the Same Color
First Claim
1. A backlight module comprising:
- an optical film set having a light incident plane; and
a plurality of light source sets disposed correspondingly to the light incident plane of the optical film set, wherein each of the light source sets includes;
at least one first light source generating a first chromaticity light; and
at least one second light source generating a second chromaticity light, the first chromaticity light and the second chromaticity light being mixed and enter the light incident plane;
wherein a spectrum of the first chromaticity light and a spectrum of the second chromaticity light both belong to a first color region, the spectrum of the first chromaticity light is close to a second color region while the spectrum of the second chromaticity light is close to a third color region.

Abstract
The present invention provides a backlight module and a manufacture method thereof using complementary light sources having the same color. The backlight module includes an optical film set and a plurality of light source sets having a first light source and a second light source. The first light source generates a first chromaticity light while the second light source generates a second chromaticity light. The first chromaticity light mixes with the second chromaticity light in the space between the light source sets and the optical film set and then enters the optical film set. The first chromaticity light and the second chromaticity light have their own spectrum and both spectra fall into a first color region of the CIE 1931 color space. Within the first color region, the spectrum of the first chromaticity light is close to a second color region while the spectrum of the second chromaticity light is close to a third color region.

18. A manufacture method of backlight modules comprising:
-
forming a plurality of light source sets, wherein each of the light source sets includes; at least one first light source generating a first chromaticity light; and at least one second light source generating a second chromaticity light, wherein a spectrum of the first chromaticity light and a spectrum of the second chromaticity light belong to a first color region, the spectrum of the first chromaticity light is close to a second color region while the spectrum of the second chromaticity light is close to a third color region; disposing the plurality of light source sets corresponding to a light incident plane of the optical film set, thus the first chromaticity light and second chromaticity light mix together and enter the light incident plane 110 of the optical film set. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)
