ABSTRACT:
A display apparatus having a backlight unit whose brightness is adjusted according to input image signals. The display apparatus processes input image signals in order for them to be appropriate to a display characteristic in an image signal processing unit and outputs each chromatic signal, R, G, and B, related to a color configuration of the image signals, processed in the chromatic signal output unit. Then a display panel drives an image display screen according to each chromatic signal. Meanwhile, a chromatic averaging unit calculates average brightness of the input images from each chromatic signal to transfer to a controller. The controller controls an inverter through an inverter current limiting unit in order for currents provided to the backlight unit in the display panel, to be controlled according to the average brightness of the input images calculated in the chromatic signal averaging unit.
