Abstract
A display device includes: an image display having at least one first display area and a second display area; a memory configured to store image data; and a timing controller configured to store first image data for the first display area in the memory after first image data for the first display area and the second display area is received from a host device, wherein the timing controller is configured to control the image display unit so as to display a first image in the first display area by loading the first image data for the first display area from the memory and to display a preset second image in the second display area.
Claims20
A display device, comprising:
- an image display having at least one first display area;
- a memory configured to store image data;
- and
- a timing controller configured to store first image data for the first display area in the memory after the first image data for the first display area is received from a host device,
- wherein the timing controller is configured to control the image display so as to display a first image in the first display area by loading the first image data for the first display area from the memory,
- wherein the timing controller is configured to generate downscaled first image data by downscaling n-bit RGB values of the first image data of the first display area or an n-bit grayscale value, which is converted from the RGB values, to m-bit data and to store the downscaled first image data in the memory, n being a natural number that is greater than 2 and m being a natural number that ranges from 1 to n−1,
- wherein the timing controller is configured to generate second image data by upscaling the downscaled first image data to n-bit data, and
- wherein the second image data is upscaled by at least one of a plurality of algorithms.
A driving method of a display device, comprising:
- receiving a control signal and first image data for a first display area from a host device;
- storing the first image data for the first display area;
- and
- displaying a first image in the first display area by loading the first image data,
- wherein storing the first image data for the first display area comprises:
- downscaling n-bit RGB values of the first image data or an n-bit grayscale value, which is converted from the RGB values, to m-bit data, n being a natural number that is greater than 2 and m being a natural number that ranges from 1 to n−1;
- and storing the downscaled first image data,
- wherein displaying the first image in the first display area by loading the first image data comprises:
- generating second image data by upscaling the downscaled first image data to n-bit data, and
- wherein the second image data is upscaled by at least one of a plurality of algorithms.
