Abstract

The invention provides a backlight module, a display device and a color correction method of the display device. The backlight module comprises a light emitting unit, a first quantum dot film and a second quantum dot film, and the light emitting unit can emit first light of a first color. The first quantum dot film can emit second light of a second color after being excited by the first light, the second quantum dot film can emit third light of a third color after being excited by the first light, and the first light, the second light and the third light can be mixed into white light; the light emitting unit at least comprises a first light emitting element and a second light emitting element, the light emitting wavelengths of the first light emitting element and the second light emitting element are different, and the first light emitting element and the second light emitting element are driven independently. According to the embodiment of the invention, the chromaticity specification evaluation period can be shortened.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module, a display device and a color correction method for the display device. Background technique [0002] Quantum dot backlight module refers to the backlight module that uses quantum dots to emit light as the backlight module of the liquid crystal panel. The quantum dot film emits light under the drive of the backlight chip, and the color of the display device using the quantum dot backlight module may be affected by the light-emitting chip. Integrative effects of quantum dot films. In order to ensure the consistency of the product, the relevant technology mainly evaluates the chromaticity of the display device, and further specifies the ratio of the quantum dot film according to the evaluation result to ensure the consistency of the display effect of the display device. The specification evaluation cycle is long. Contents of the invention [0003] Embodiment...
