LIGHT SOURCE MODULE AND BACKLIGHT DEVICE

摘要

A light source module (30) used in backlight device (100, 200) is provided. The light source module (30) comprises a plurality of light source groups (301). The light source group (301) comprises at least one first light emitting diode (321) with first chromaticity in first wavelength range and at least one second light emitting diode (322) with second chromaticity in second wavelength range. The chromaticity of the light which is mixed by the light emitted from the first and second light emitting diode (321, 322) and passes through an optical glass element group is equal to the chromaticity of the light which is emitted from the light emitting diode with centre-chromaticity in first wavelength range or in second wavelength range and passes through the optical glass element group.
