First Claim
1. A display device comprising:
- a plurality of gate lines;
a plurality of data lines which cross the plurality of gate lines;
a display panel which comprises a plurality of pixels connected to the plurality of the gate lines and the plurality of the data lines;
a data driver configured to drive the plurality of data lines;
a gate driver configured to drive the plurality of gate lines;
a backlight unit which comprises a plurality of light emitting diodes (LEDs) configured to supply light to the display panel, and which is configured to output a rank signal corresponding to a rank of the plurality of LEDs, the rank of the plurality of LEDs corresponding to a color coordinate of light emitted from the plurality of LEDs; and
a control unit configured to convert a first image signal into a second image signal in response to the rank signal, and configured to provide the second image signal to the data driver.

Abstract
A display device includes a display panel with a plurality of pixels connected to a plurality of gate lines and a plurality of data lines, a data driver driving the plurality of data lines, a gate driver driving the plurality of gate lines, a backlight unit which includes a plurality of Light Emitting Diodes (LEDs) supplying light to the display panel, and a control unit. The backlight unit outputs a rank signal corresponding to a rank of the LEDs, where the rank of the LEDs corresponds to a color coordinate of light emitted from the LEDs. The control unit controls the data driver, the gate driver, and the backlight unit in response to a first image signal and a control signal, converts the first image signal into a second image signal in response to the rank signal, and provides the second image signal to the data driver.
