Abstract

The invention discloses a light-emitting diode (LED) strip structure and a backlight module. The LED strip structure is provided with a plurality of light source sets; each light source set comprises a first LED and a second LED, and moreover, the chromaticity of each first LED and the chromaticity of each second LED are complementary. Therefore, uniform and consistent white light can be formed by mixing in the whole LED strip structure without considering the chromaticity used by other light sources, thereby, the phenomenon that the color and the emitted light are not uniform on a backlight module cannot be generated, the materials of the LEDs cannot be wasted, and the chromaticity among different backlight modules can also be controlled to be consistent.

Description

【Technical field】 [0001] The invention relates to a light emitting diode light bar structure and a backlight module, in particular to a light emitting diode light bar structure and a backlight module using two complementary colors as a light source group. 【Background technique】 [0002] Liquid crystal display (liquid crystal display, LCD) is a flat panel display device (flat panel display, FPD) that uses the characteristics of liquid crystal materials to display images. Power consumption and other advantages have become mainstream products in the entire consumer market. However, the liquid crystal material of the liquid crystal display cannot emit light by itself, and an external light source must be provided. Therefore, a backlight module is additionally provided in the liquid crystal display to provide the required light source. [0003] Generally speaking, the backlight module can be classified according to the size of the light tube and the position of the light tube, a...
