Abstract: The present invention provides a backlight module comprising a LED backlight source. The LED backlight source comprises at least two LED light source sets disposed alternatively; each LED light source set comprises red LED lights, green LED lights and blue LED lights arranged in array formation; and a color gamut of the red and green LED lights in two neighbored LED light source sets are different. The present invention further provides a control method of display device. The LED backlight source is controlled and a corresponded RGB grey level is output to the display device according to the percentage of the areas of the red and green pixels having color saturation value greater than the color saturation threshold. Comparing to the existed technology, uncomfortableness on watching red pixels and green pixels is reduced and comfort of human eyes while watching images with high color gamut is improved.
