Abstract
Disclosed are a tiled display and an optical compensation method thereof. The tiled display includes a color coordinate compensation circuit configured to convert color coordinates of pure color data to be displayed in display panels into target color coordinates having a color gamut smaller than a color gamut defined in color coordinates of each of display panels, and convert the pure color data into a data combination of two or more different colors.
Claims8
A tiled display, comprising:
- two or more display panels;
- and
- a color coordinate compensation circuit configured to:
- convert color coordinates of pure color data to be displayed in the two or more display panels into target color coordinates having a color gamut smaller than a color gamut defined in color coordinates of each of the two or more display panels, and
- convert the pure color data into a combination of two or more different color data,
- wherein the color coordinate compensation circuit is configured to convert the pure color data into a combination of two or more pure color data or a combination of one or more pure color data and a white data,
- wherein the color coordinate compensation circuit is configured to convert a first pure color data into any one of a combination of a first pure color and a second pure color;
- a combination of the first pure color and a third pure color;
- a combination of the first pure color and a white:
- a combination of the first pure color, the second pure color, and the third pure color;
- a combination of the first pure color, the second pure color, and the white;
- and a combination of the first pure color, the third pure color, and the white, and
- wherein when luminance of the first pure color is 100%, a luminance ratio of the first pure color in the color combinations exceeds 50%.
