1. A display device comprising:
a plurality of subpixels of a first color;
a plurality of subpixels of a second color;
a plurality of subpixels of a third color, wherein the plurality of subpixels of the first, second, and third colors are arranged in an array, the array having a plurality of rows and a plurality of columns, with rows of the array including subpixels arranged in a repeating pattern of subpixels of the first color, the second color, the third color, and the second color, and with alternating columns of the array including subpixels: (a) arranged in a repeating pattern of a subpixel of the first color and a subpixel of the third color, and (b) having only subpixels of the second color;
a plurality of scan lines;
a plurality of column lines;
each subpixel in a column of the array being electrically connected to a same column line of the plurality of column lines and each of the subpixels in a column being configured for receiving electronic scan signals from a scan line and from the column line connected to the subpixel, wherein the received signals control a light output from an emissive element of the subpixel; and
one or more line drivers configured for providing the electronic scan signals, during a time period for rendering a frame on the display device:
(i) to subpixels in a first column of subpixels, first to multiple subpixels of the first color in a sequential order and then to multiple subpixels of the third color in a sequential order, and
(ii) to subpixels in a second column of subpixels, first to multiple subpixels of the third color in a sequential order and then to multiple subpixels of the first color in a sequential order.
