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.
Claims16
A tiled display comprising:
- 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,
- wherein, 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,
- wherein the distance data is based on a distance between adjacent pixels in the adjacent display devices or a distance between outermost portions of the adjacent display devices,
- wherein the main controller generates the corrected image signal when a distance provided by the distance data is within a predetermined value, and generates a normal image signal when the distance provided by the distance data is outside of the predetermined value, and
- wherein even if the distance is within the predetermined value, when a black image is displayed near the boundary portion, the main controller generates a normal image signal.

An image correction method of a tiled display including a plurality of display devices, comprising:
- generating distance data between adjacent display devices among the plurality of display devices;
- generating a corrected image signal that increases luminance near a boundary portion of the adjacent display device, based on an input image signal and the distance data;
- and
- displaying a corrected image with increased luminance near the boundary portion according to the corrected image signal,
- wherein the corrected image signal generates the corrected image signal when a distance provided by the distance data is within a predetermined value, and
- wherein even if the distance is within the predetermined value, when a black image is displayed near the boundary portion, a normal image signal is generated.
