Abstract: A display device includes a degradation compensator, a controller, a data driver, and a display panel. The degradation compensator generates a first fitting function and a second fitting function based on image data, generates a compensation function through a harmonic mean of the first and second fitting functions, and generates a compensation value based on the compensation function. The controller receives the compensation value, and generates input image data to which the compensation value is applied. The data driver receives the input image data to which the compensation value is applied, and converts the input image data into a data voltage. The display panel includes pixels, in which each of the pixels includes a pixel circuit which receives the data voltage and a light-emitting element electrically connected to the pixel circuit.

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.
