Abstract: A display device includes a display substrate having a fan-out area, and a plurality of driving integrated circuits are arranged to reduce a signal delay variation. A printed circuit board (PCB) is connected to the fan-out area, and a driving integrated circuit (IC) is disposed on the PCB in a second direction. A first circuit board wiring is disposed on the PCB and connected to the driving IC. A second circuit board wiring is disposed in the second direction and connected to the driving IC. A first fan-out wiring is disposed on the fan-out area and connected to the first circuit board wiring, and a second fan-out wiring is disposed in the second direction from the fan-out area and connected to the second circuit board wiring. A sum of the length of the wiring of the first circuit board and the second circuit board may be substantially the same.

Abstract: A display apparatus includes a display panel configured to display an image. The display panel includes a plurality of display areas. A display panel driver is configured to output a driving signal to the display panel. A backlight unit is configured to provide light to the display panel. A luminance compensating part is configured to generate a backlight compensating signal having different compensating values according to a distance between the display panel driver and the display areas of the display panel.
