Abstract
The present disclosure relates to a display device and a rendering method thereof which can reduce pattern artifacts by controlling padding data using data of a plurality of pixels neighboring a boundary, and a rendering method of a display device according to an embodiment determines smaller data or luminance values for respective colors between first and second pixel data neighboring a boundary as padding data and renders the padding data and any one of the first and second pixel data immediately neighboring the boundary for the respective colors.
Claims13
A display device, comprising:
- a panel in which each pixel is composed of subpixels of at least two colors from among three colors and has a different subpixel arrangement structure from those of pixels neighboring in a vertical direction and a horizontal direction;
- a panel driver for driving the panel;
- and
- a processor configured for
- determining whether a position of a current pixel is at a boundary at which a previous pixel or a next pixel is not positioned;
- determining smaller values between current pixel data and neighboring pixel data as padding data when the position of the current pixel is at the boundary;
- calculating the determined padding data and the current pixel data for respective colors to perform a subpixel rendering process;
- and
- outputting the rendered data to the panel driver.
A rendering method of a display device, comprising:
- determining whether a position of a current pixel is at a boundary at which a previous pixel or a next pixel is not positioned;
- comparing smaller values between current pixel data and neighboring pixel data;
- determining the smaller values as padding data when the position of the current pixel is at the boundary;
- and
- calculating the determined padding data and the current pixel data for respective colors to perform a subpixel rendering process.
A rendering method of a display device, comprising:
- determining one or both of smaller data or luminance values for respective colors between first and second pixel data neighboring a boundary as padding data;
- and
- rendering the padding data and any one of the first and second pixel data immediately neighboring the boundary for respective colors.
