Abstract
An image data is filtered to output filtered image data, the filtered image data is stored to a frame memory, and each of a plurality of light emitting elements of a display device is controlled according to the filtered image data in the frame memory to make the display screen display the image data. When a first figure and a second figure are drawn adjacently, the first figure and the second figure are extended such that the first figure and the second figure have an overlap area. Thanks to the overlap area, a background image does not affect in the overlap area, thereby a front of discontinuity, which is not expected, does not appear.
Claims14
A display method, using a display device having a display screen, the display screen having a plurality of lines, each of the plurality of lines having a plurality of pixels in a fixed order, each of the plurality of pixels having a plurality of light emitting elements, each of the plurality of light emitting elements corresponding to one of a plurality of pixel sub-components, the display method comprising:
- filtering image data using a filter having taps to output filtered image data comprising the plurality of pixel sub-components;
- storing the filtered image data to a frame memory;
- and
- controlling each of the plurality of light emitting elements according to the filtered image data comprising the plurality of pixel sub-components in the frame memory to make the display screen display the image data,
- wherein, when a first figure and a second figure are drawn adjacently, figure extension in at least one of the first figure and the second figure is performed such that the first figure and the second figure have an overlap area.
A display method, using a display device having a display screen, the display screen having a plurality of lines, each of the plurality of lines having a plurality of pixels in a fixed order, each of the plurality of pixels having a plurality of light emitting elements, each of the plurality of light emitting elements corresponding to one of a plurality of pixel sub-components, the display method comprising:
