the longest center lines of the second and third sub-pixels extend along the first direction x, and the longest center line of the first sub-pixel extends along the second direction y.
Because of the difference of the luminescent materials of the red sub-pixel, the green sub-pixel and the blue sub-pixel, the service life of the blue sub-pixel is shortest in normal cases, the service lives of the red sub-pixel and the green sub-pixel are almost the same, and the service life of the green sub-pixel is slightly smaller than that of the red sub-pixel in normal cases.
