Abstract
A method of driving light-emitting diodes (LEDs), a backlight assembly for performing the method, and a display apparatus having the backlight assembly are disclosed for various embodiments. For example, the backlight assembly includes a light source unit and a light source controller. The light source unit includes red, green, and blue LEDs generating red, green, and blue light, respectively. The light source controller detects amounts of the red, green, and blue light, respectively, to compare the actual light amount ratio of the red, green, and blue light with the reference light amount ratio. The light source controller controls the red, green, and blue LEDs, respectively, so that an actual light amount ratio becomes substantially identical to a reference light amount ratio when the actual light amount ratio is not identical to the reference light amount ratio.
