Abstract
A curved display device includes a curved panel including a plurality of pixels, and an image compensation processor. The image compensation processor is configured to convert a first image signal into a second image signal by scaling the first image signal based on a curvature of the curved panel and a viewing distance between a viewer and the curved panel, map the second image signal onto corresponding pixels of the curved panel, and provide the mapped second image signal to the corresponding pixels of the curved panel.
Claims15
A curved display device comprising:
- a curved panel including a plurality of pixels;
- and
- an image compensation processor, wherein the image compensation processor is configured to:
- convert a first image signal into a second image signal by scaling the first image signal based on a curvature of the curved panel and a viewing distance between a viewer and the curved panel,
- map the second image signal onto corresponding pixels of the curved panel,
- provide the mapped second image signal to the corresponding pixels of the curved panel, and
- scale the first image signal by a first ratio based on the viewing distance,
- wherein the first ratio increases as the viewing distance decreases.
A curved display device comprising:

- map the second image signal onto corresponding pixels of the curved panel,
- provide the mapped second image signal to the corresponding pixels of the curved panel, and
- scale the first image signal by a first ratio based on the viewing distance,
- wherein the first ratio increases as a radius of the curvature decreases.
A method for driving a curved display device, the curved display device comprising a curved panel including a plurality of pixels, the method comprising:
- determining a viewing distance between a viewer and the curved panel;
- scaling a first image signal based on the viewing distance and a curvature of the curved panel, so as to convert the first image signal into a second image signal by enlarging a first image associated with the first image signal by a first ratio;
- and
- mapping the second image signal onto corresponding pixels of the curved panel, and providing the mapped second image signal to the corresponding pixels of the curved panel,
- wherein the first ratio increases as the viewing distance decreases.
