1. A pixel array, comprising a plurality of first basic pixel units arranged in odd-numbered rows and a plurality of second basic pixel units arranged in even-numbered rows; wherein each of the first basic pixel units comprises a first sub-pixel group, a second sub-pixel group, and a third sub-pixel group arranged sequentially in a row direction; each of the second basic pixel units comprises the third sub-pixel group, the first sub-pixel group, and the second sub-pixel group arranged sequentially in the row direction; the first sub-pixel group comprises two first sub-pixels arranged in a column direction; the second sub-pixel group comprises two second sub-pixels arranged in the column direction; the third sub-pixel group comprises two third sub-pixels arranged in the column direction; the first sub-pixel, the second sub-pixel and the third sub-pixel have different colors; wherein
the first basic pixel units in the even-numbered rows are aligned in the column direction;
the second basic pixel units in the odd-numbered rows are aligned in the column direction;
light emitting layers of the two first sub-pixels in the first sub-pixel group are continuous, light emitting layers of the two second sub-pixels in the second sub-pixel group are continuous, and light emitting layers of the two third sub-pixels in the third sub-pixel group are continuous; and
there is a distance D, in the row direction, between a boundary of the first sub-pixel group away from the second sub-pixel group in the first basic pixel unit and a boundary of the third sub-pixel group away from the first sub-pixel group in the second basic pixel unit closest to the first basic pixel unit in an adjacent row; the distance D is greater than or equal to zero and less than or equal to a sum of a width of the first sub-pixel group in the row direction, a width of the second sub-pixel group in the row direction and a distance between the first sub-pixel group and the second sub-pixel group in the row direction.
