A four-color organic light-emitting device having pixels which emit light
includes a substrate; pixels arranged in rows and columns and each pixel
including groups of four subpixels disposed over the substrate and wherein
each subpixel includes spaced apart first and second electrodes; and
organic EL media disposed between the first and second electrodes of each
subpixel. The device also includes drive circuitry disposed relative to
the organic EL media over the substrate and arranged to drive each group
of four subpixels and having an electrical connection to the first
electrode corresponding to each subpixel, and wherein the drive circuitry
for each group of four subpixels including four data lines, two power
lines, and one select line, the four data lines being shared for each
column of the array of pixels, and the select line being shared for each
row of the array of pixels.
