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.

Abstract: A display system includes a measurer, a measured data filter and a compensation data generator. The measurer measures an image at a measuring point of a display panel to generate measured data. The measured data filter removes a false measured data outside an allowable range among the measured data. The compensation data generator generates representative compensation data compensating the image based on the measured data in which the false measured data is removed.

Abstract: A liquid crystal display device includes a liquid crystal display panel including a plurality of pixels, a voltage generator generating a gate on voltage and a gate off voltage, a gate driver generating a gate signal provided to the pixel using the gate on voltage and the gate off voltage, and providing the gate signal to the pixels, a data driver providing a data signal to the pixels, and a timing controller generating control signals that control the gate driver and the data driver. Each of the pixels includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel. A voltage level of the gate off voltage provided to the red sub-pixel, a voltage level of the gate off voltage provided to the green sub-pixel, and a voltage level of the gate off voltage provided to the blue sub-pixel are different from one another.
