An apparatus includes an active region, a source driving circuit, and a light emitting driving circuit. The active region includes an array of light emitting elements corresponding to an array of pixels arranged in M rows and N columns. The number of the array of light emitting elements is k times of the number of the array of pixels. The apparatus includes xM light emitting lines and (k/x)N source lines, wherein x is a positive fraction, and each of xM and (k/x)N is a positive integer. The source driving circuit is operatively coupled to the active region via the (k/x)N source lines and configured to write display data of a frame to the array of light emitting elements. The light emitting driving circuit is operatively coupled to the active region via the xM light emitting lines and configured to cause the array of light emitting elements to emit light.
