Document Type and Number:
WIPO Patent Application WO/2023/216677
Kind Code:
A1
Abstract:
A backlight module and a preparation method therefor, and a liquid crystal display panel. According to the backlight module (10), a quantum dot element containing a fluorescence-quenched quantum dot material is matched with an LED light source (11) for use, and the characteristic that the fluorescence-quenched quantum dot absorbs light and does not emit light and the characteristic that the absorption band is adjustable are utilized to absorb light in a crosstalk waveband, such that the color gamut is improved, and the display effect is better. In addition, compared with a light-emitting quantum dot material, the fluorescence-quenched quantum dot material has the advantages of high stability, low reliability process requirements and low cost.
