Abstract: A display apparatus includes: a backlight to generate light; a display panel to display an image by utilizing the light; a driving part to provide image signals corresponding to the image to the display panel; and a timing controller to drive the backlight, to drive the driving part at a first frequency when the image is a moving image, and to drive the driving part at a second frequency lower than the first frequency when the image is a still image. The timing controller is to set the second frequency based on a value obtained by applying a reduction rate of a flicker index corresponding to a dimming index of the backlight to a flicker index of image signals of a previous frame.

Abstract: A tiled display device includes a plurality of display panels coupled to each other, where each of the plurality of display panels includes an edge region adjacent to a boundary line between the plurality of display panels, and a panel driver which multiplies input gray levels of input image data for the plurality of display panels by an adaptive gain, generates boundary compensated image data by adding boundary compensation gray levels to the input gray levels multiplied by the adaptive gain for the edge region, and drives the plurality of display panels based on the boundary compensated image data. The adaptive gain is gradually decreased over a plurality of frame periods in a case where a sum of each of the input gray levels for the edge region and a corresponding one of the boundary compensation gray levels exceeds a maximum gray level.
