A device for driving a display backlight, a method for driving a display backlight, and a display apparatus having a backlight driving device. The device, method, and display apparatus are capable of displaying a substantially uniform white light. A sensing unit senses light intensities for each of a plurality of colors of light emitted by the light emitting elements, and outputs sensing signals for each of the plurality of colors of light emitted by the light emitting elements. The signal processing unit processes the outputted sensing signals to output light intensity signals for each of the plurality of colors of light emitted by the light emitting elements. The control unit controls the light emitting elements to generate a substantially uniform white light by outputting driving signals based on the light intensity signals and a set of reference light intensity signals to control each of the plurality of colors of light emitted by the light emitting elements. Accordingly, increased uniformity of white light is provided.
