That seems like a reasonable article.

Reading a little more about rod and cone distribution it seems like a non striped configuration could really makes a lot of sense. From hyperphysics I found the distribution of cones by color is "red" cones (64%), "green" cones (32%), and "blue" cones (2%) . Additionally, chromatic aberration causes the blue to be slightly out of focus. However, your brain is more sensitive to the signals from blue cones to compensate but this still doesn't overcome. Additionally, many of these blue cones are outside the forvea which is sort of the high resolution part of your eye. It would therefore seem to make sense to cut the number of blue pixels in favor of more green and red pixels. Not sure what the arrangement would be and you would still want to be able to make pure white. Maybe just replacing half the blue pixels in an RG BG arrangement with white pixels.

Another idea...
I wonder what it would be like if instead of using RG and BG pixels one used three sub pixel types. Something like RedCyan, MagentaGreen, YellowBlue. In this design all pixels would be able to render a perfect greys and 1/3rd the color information. In rg bg neither pixel can render gray but instead render 1/2 the color information. Your eyes have way higher resolution for black and white than color so maybe this would produce a better looking display with fewer sub-pixels.
