Abstract
In some examples, a non-transitory machine-readable medium stores machine-readable instructions. When executed by a controller, the machine-readable instructions cause the controller to drive a first subset of multiple light sources of a display device using a first color gamut matrix and drive a second subset of the multiple light sources of the display device using a second color gamut matrix. A light source of the second subset is a same type of light source as a light source of the first subset.
Claims17
A display device, comprising:
- a display panel;
- and
- a controller coupled to the display panel, the controller to:
- receive a first original color gamut matrix and a target color gamut, the target color gamut is a first target color gamut of multiple color gamuts;
- receive a first priority and a first coordinate indicated by the first original color gamut matrix, the first coordinate associated with a pixel of an image;
- determine a first color conversion based on the first original color gamut matrix and the first target color gamut;
- generate a first converted color gamut matrix based on the first color conversion, the first converted color gamut matrix based on the first color gamut of the multiple color gamuts;
- cause a light source of the display panel to display the pixel of the image using the first converted color gamut matrix;
- receive a second original color gamut matrix and a second target color gamut, the second target color gamut being a second color gamut of the multiple color gamuts, the first color gamut being different than the second color gamut;
- receive a second priority, and a second coordinate indicated by the second original color gamut matrix, the second coordinate associated with the pixel of the image;
- determine that the second priority is higher than the first priority;
- determine a second color conversion based on the second original color gamut matrix and the second target color gamut;
- generate a second converted color gamut matrix based on the second color conversion;
- and
- cause a second light source of the display panel to display a second pixel of the image using the second converted color gamut matrix.

A display device, comprising:
- a display panel having first and second areas, the first area having a first light source and the second area having a second light source, wherein the display panel has a third area having the first light source;
- and
- a controller coupled to the display panel, the controller to:
- cause the display panel to display a first image in the first area using the first light source and a first color gamut matrix;
- cause the display panel to display the first image in the second area using the second light source and the first color gamut matrix;
- cause the display panel to display a second image in the first area using the first light source and a second color gamut matrix;
- determine a third image for display in the third area has a higher priority than a priority of the first image for display in the first area;
- and
- cause the display panel to display the third image in the third area using the first light source and a third color gamut matrix.
6 more elements
A display device comprising:
- a display panel;
- and a controller coupled to the display panel, the controller to:
- cause the display panel to display at least a first portion of an image in a first area of the display panel according to a first color gamut;
- and when the first portion of the image in the first area is displayed, cause the display panel to display a second portion of the image in a second area of the display panel according to a second color gamut, the first color gamut being different than the second color gamut;
- and a second image in a third area of the display panel according to a third color gamut, the third color gamut being different than the first color gamut.
