Abstract: A display panel includes pixels arranged in an array in a first direction and a second direction. Each pixel includes a first sub-pixel having a first light-emitting zone to emit light of a first color, a second sub-pixel having a second light-emitting zone to emit light of a second color, and a third sub-pixel having a third light-emitting zone to emit light of a third color. The first, second, and third light-emitting zones are arranged in a triangle such that the first, second, and third light-emitting zones cover respective vertices of the triangle, with one side of the triangle being substantially parallel to the first direction. Any two pixels directly adjacent in the first direction have respective patterns of first, second, and third light-emitting zones, which are substantially mirror-symmetrical to each other. Any two diagonally adjacent pixels have a substantially repeating pattern of first, second and third light-emitting zones.
