Patent number: 8803788Abstract: 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.
