LIGHT-EMITTING UNIT AND METHOD FOR ADJUSTING LIGHT-EMITTING SPECTRUM THEREOF, BACKLIGHT MODULE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A light-emitting unit and a method for adjusting a light emitting spectrum thereof, a backlight module, and a liquid crystal display device. The light-emitting unit comprises a light source (1130) and a color filter layer (120) located at a light exit side of the light source (1130). The color filter layer (120) comprises at least two colors of color filters (121) arranged in an array, and the color filter layer (120) is configured to have different transmittances for at least two colors in white light emitted by the light source (1130). The adjustment on a spectrum of the light-emitting unit can improve the color gamut of a display device comprising the light-emitting unit.
