A light source (10), backlight module (100) and display device; the light source (10) comprises: a light emitting diode chip (3); and a fluorescent powder layer (2) provided opposite to the light emitting diode chip (3), the fluorescent powder layer (2) receives a first light emitted by the light emitting diode chip (3), and emits a second light having a wavelength different from that of the first light; the light emitting diode chip (3) and the fluorescent powder layer (2) are movable relative to each other, thereby increasing or reducing the amount of fluorescent powder of the fluorescent powder layer (2) excited by the light emitted by the light emitting diode chip (3). The technical solution enables the light emitting diode chip (3) to move relative to the fluorescent powder layer (2), thus simplifying the adjustment of backlight color temperature. |
