WHITE LED LIGHT SOURCE, BACKLIGHT MODULE AND DISPLAY DEVICE
First Claim
1. A white LED light source comprising a light strip having a plurality of LED units and a plurality of laser units,wherein each LED unit has a chip emitting lights of a first color light and a fluorescent module induced by the lights of the first color to emit lights of a second color;
- the plurality of laser units emit lights of a third color so as to form white lights by mixing the lights of the second color emitted by the LED units and the lights of the third color emitted by the laser units.

Abstract
The present disclosure relates to a white LED light source, a backlight module and a liquid crystal display device. The white LED light source comprises a light strip having a plurality of LED units and a plurality of laser units. Each LED unit has a chip emitting lights of a first color light and a fluorescent module induced by the lights of the first color to emit lights of a second color. The plurality of laser units emit lights of a third color so as to form white lights by mixing the lights of the second color emitted by the LED units and the lights of the third color emitted by the laser units. In the white LED light source according to the present disclosure, laser units are used so as to expand the color gamut of the liquid crystal display device.
