Abstract
Disclosed are methods for compensating colors based on virtual chromaticity coordinate points and the related display devices. The present disclosure provides an electronic device. The electronic device comprises: a display comprising an array of pixels and a control circuit electrically connected to the display. Pixels in the array comprise 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 is configured to receive an input image signal and generate a control signal to the display for driving each pixel of the display to output light in a virtual color gamut. The virtual color gamut of the display is among the first, second and third color areas on the chromaticity plane and does not overlap any of the first, second or third color areas.
