Abstract
The present invention discloses a light emitting diode (LED) light bar structure and a backlight module. The LED light bar structure is provided with a plurality of the light source sets. Each of the light source sets comprises a first LED and a second LED, and the chromaticity of the first LED and the chromaticity of the second LED are complementary. Hence, it is not necessary to consider with the others of the light source sets, so that it can achieve mixing a uniform white light, and the backlight module will not appear the phenomenon of “Mura”. Besides, the material of the LED will not be wasted, and it is easy to control the identical chromaticity between the different backlight modules.
