Electronic devices, methods of operating display units, and methods of color compensation for display units

Abstract

The invention refers to methods (300, 310, 320) to compensate for colors based on brightness adjustment parameters and display devices with 1100. The electrical device (100) includes; the display includes a screen of pixels (210, 220, 230, 240) and a control circuit (130) which is electrically connected to the display. The pixels (210, 220, 230, 240) in the array consist of many first-order subpixels defining the first color region (401, 501) in the color plane (400, 500, 800, 1000, 1100, 1200, 1300), many second-order subpixels defining the second color region (402, 502) in the color plane (400, 500, 800, 1000, 1100, 1200, 1300), and many third-order subpixels defining the third color region (403, 503) in the color plane (400, 500, 800, 1000, 1100, 1200, 1300). 1300). Many of the first subpixels are linked to the first primary color, many of the second subpixels are linked to the second primary color, and many of the third subpixels are linked to the third primary color. The control circuit (130) is configured to receive the input image signal and generate a control signal for the display to control each pixel of the display to output light in the color gamut (817, 1019, 1117, 1217, 1219, 1317). The virtual color gamut (817, 1019, 1117, 1217, 1219, 1317) of the display family consists of the first virtual color gamut, which includes the coordinate point of the first degree of the first primary color; the second virtual color gamut, which includes the coordinate point of the second degree of the second primary color; the third virtual color gamut, which includes the coordinate point of the third degree of the third primary color; and the fourth virtual color gamut. The fourth virtual color gamut is within the first, second, and third color areas (401, 501, 402, 502, 403, 503) on the tonal plane (400, 500, 800, 1000, 1100, 1200, 1300) and does not overlap any color area within the first, second, or third color areas (401, 501, 402, 502, 403, 503).
