Abstract: A method of performing an image-adaptive tone-mapping for a display device including performing a first tone-mapping on an image frame by applying a first tone-mapping function to respective non-target display blocks, and performing a second tone-mapping on the image frame by applying a second tone-mapping function obtained by applying a local weighted value to the first tone-mapping function to respective target display blocks.

Abstract: A method of performing image-adaptive tone mapping includes: determining a tone mapping curve based on a data signal corresponding to an image frame to be displayed on a display panel; determining whether a scene-change occurs between the image frame and a previous image frame by comparing the data signal with a previous data signal corresponding to the previous image frame; generating, in response to a determination that the scene-change does not occur, a final tone mapping curve based on the tone mapping curve and a previous tone mapping curve, which is applied to the previous image frame; determining, in response to a determination that the scene change occurs, the tone mapping curve as the final tone mapping curve; and performing a tone mapping by applying the final tone mapping curve to the image frame.

Abstract: A display device includes a display panel including a first non-folding area, a folding area, and a second non-folding area and a support plate that is disposed under the display panel and that defines a plurality of openings overlapping the folding area and arranged in a first direction and a second direction intersecting the first direction. The support plate includes a first branch disposed between openings adjacent to each other in the second direction among the plurality of openings and a second branch disposed between openings adjacent to each other in the first direction among the plurality of openings. A first width of the first branch in the second direction is smaller than a second width of each of the openings in the second direction.
