Abstract

A pixel architecture includes a plurality of pixel cell groups disposed in parallel in a row direction. Each pixel cell group includes a plurality of pixel cells disposed in parallel in a column direction. Each pixel cell includes one first sub-pixel and two second sub-pixels. The first sub-pixels in a same pixel cell group are disposed adjacently in sequence in the column direction. The second sub-pixels in a same pixel cell group are disposed adjacently in sequence in the column direction. In a same pixel cell group, one second sub-pixel in each pixel cell and another second sub-pixel that is in another adjacent pixel cell and is adjacent to the second sub-pixel have a same color.
