Methods for compensating colors and adjusting brightness and related display devices

Abstract

Embodiments of the present disclosure relate to an electronic device. The electronic device comprises a display comprising an array of pixels and a control circuit electrically connected to the display. Pixels of the array of pixels includes a plurality of first sub-pixels defining a first color area on a chromaticity plane, a plurality of second sub-pixels defining a second color area on the chromaticity plane, and a plurality of third sub-pixels defining a third color area on the chromaticity plane. The control circuit comprises a processor and a memory unit. The processor configured to receive an input image signal; based on the input image signal and a compensation matrix, generate a control signal for controlling a pixel of the display to emit light in a virtual color gamut, which is among the first, second, and third color areas does not overlap any of the first, second, or third color areas on the chromaticity plane, wherein the compensation matrix is determined according to the first, second, and third color areas; perform brightness adjustment on the control signal to generate a pixel driving signal for driving the pixel of the display; and output the pixel driving signal to the display for driving each pixel of the display to output light.
