Abstract

The invention discloses a display device, a backlight module and a backlight source. The backlight source comprises multiple light-emitting unit LED particles and a connecting circuit, wherein each LED particle comprises a first cavity, a second cavity, a first light-emitting chip, a first fluorescent powder mixture, a second light-emitting chip and a second fluorescent powder mixture, the first cavity and the second cavity are mutually independent, the first light-emitting chip and the first fluorescent powder mixture are arranged in the first cavity, the second light-emitting chip and the second fluorescent powder mixture are arranged in the second cavity, the light produced by the second fluorescent powder mixture and the light produced by the first fluorescent powder mixture are different in chromaticity. The connecting circuit is connected with the first light-emitting chip and the second light-emitting chip respectively and used for exerting first current to the first light-emitting chip and exerting second current to the second light-emitting chip, wherein the first current and the second current are adjustable in proportion. The chromaticity adjustment of the backlight source can be achieved by adjusting the current portion of the two chips of the LED particles, chromaticity adjustment of the backlight module can be achieved, and the display effect of a liquid crystal display panel is also not affected.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device, a backlight module and a backlight light source. Background technique [0002] A liquid crystal display device is a passive light-emitting display device. The liquid crystal panel itself does not emit light, but is illuminated by a backlight module under the liquid crystal panel. The backlight module includes a backlight light source, a light guide plate, a reflector and an optical film, etc. When the light emitted by the backlight module is irradiated on the LCD panel, the light will first pass through the lower polarizer upwards. At this time, different LCD panels will follow the Its own mechanism changes the polarization direction of the light, and then the light hits the color filter to produce color, and finally enters the upper polarizer. After the polarization direction is changed by the liquid crystal, part of the light can be emitted,...
