Abstract: A method of generating information to control display of images providing a display device with align pattern data to which box data having a maximum reference gray level is added, obtaining a first capture image generated based on the align pattern data to which the box data is added, providing the display device with one or more full pattern data respectively having one or more reference gray levels lower than the maximum reference gray level, and obtaining one or more second capture images generated based on the one or more full pattern data. The method also includes generating compensation data including compensation values at the one or more reference gray levels and the maximum reference gray level. The compensation data may be generated based on the one or more second capture images and a portion of the first capture image corresponding to the box data.

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.

Abstract: A display device includes a display panel including pixels connected to emission lines, a controller configured to receive a control signal, and to generate an emission start signal, a first emission clock signal and a second emission clock signal, and an emission driver configured to provide emission signals to the pixels through the emission lines in response to the emission start signal, the first emission clock signal and the second emission clock signal. The controller is further configured to determine an off period ratio for the pixels in units of two or more frame periods in response to the dimming signal. The control signal may be a dimming signal, a low power mode signal, or another type of signal indicative of operation of the display device.
