Abstract: A tiled display includes a plurality of display devices respectively including a plurality of pixels, and a main controller that processes an input image signal to provide an image signal to the plurality of display devices. Based on distance data between adjacent display devices among the plurality of display devices, the main controller generates a corrected image signal that increases luminance near a boundary portion of the adjacent display devices.

Abstract: A display apparatus includes a display panel displaying an image based on an input image data, a data driver outputting a data voltage to a data line, and a driving controller determining a driving frequency of the display panel based on the input image data. The driving controller includes a flicker value storage configured to store flicker values for grayscale values corresponding to the input image data, a voltage drop determiner configured to adjust a flicker value of the flicker values based on a voltage drop of the display panel, a still image determiner configured to determine whether the input image data is a still image or a video image, and a driving frequency determiner configured to determine the driving frequency of the display panel using the flicker value based on the input image data being the still image.

Abstract: A display device comprises a pixel configured to be driven in cycle periods during a frame period defined by a vertical start signal, and a display driver configured to divide a cycle period into subfields for driving, configured to control an amount of current flowing through the pixel and to control emission on-duties of the subfields, and configured to independently determine, for the cycle period, a reference duty that is a minimum emission on-duty set in the cycle period based on a dimming signal.
