A directional display device comprising: a display panel comprising a subpixel repeating group having subpixels (2414, 2416, 2412) in at least first, second and third primary colors; said subpixel repeating group comprising twelve subpixels disposed in two rows, wherein the subpixel repeating group comprises four quadrants of exactly three subpixels each; said subpixel repeating group further comprising only one subpixel each of said second and third primary colors in each row; and wherein the second primary colour subpixels are disposed at the same positions within diagonally opposing quadrants, and wherein the third primary colour subpixels are disposed at the same positions within diagonally opposing quadrants, such that the second and third primary colour subpixels (2416, 2412) form an alternating pattern along rows and along columns; driver circuitry configured to send a signal to each subpixel on said display panel; and an optical directing component configured to direct light emissions from a first column of the subpixel repeating group on said display panel to a first viewing window, configured to direct light emissions from a second column of the subpixel repeating group on said display panel to a second viewing window, and configured to direct light emissions from a third column of the subpixel repeating group on said display panel to both said first and second viewing windows, the third column having the alternating pattern of the second and third primary colour subpixels (2416, 2412), such that when an observer positions left and right eyes in said respective first and second viewing windows, the observer perceives a three-dimensional image. a display panel comprising a subpixel repeating group having subpixels (2414, 2416, 2412) in at least first, second and third primary colors; said subpixel repeating group comprising twelve subpixels disposed in two rows, wherein the subpixel repeating group comprises four quadrants of exactly three subpixels each; said subpixel repeating group further comprising only one subpixel each of said second and third primary colors in each row; and wherein the second primary colour subpixels are disposed at the same positions within diagonally opposing quadrants, and wherein the third primary colour subpixels are disposed at the same positions within diagonally opposing quadrants, such that the second and third primary colour subpixels (2416, 2412) form an alternating pattern along rows and along columns; driver circuitry configured to send a signal to each subpixel on said display panel; and an optical directing component configured to direct light emissions from a first column of the subpixel repeating group on said display panel to a first viewing window, configured to direct light emissions from a second column of the subpixel repeating group on said display panel to a second viewing window, and configured to direct light emissions from a third column of the subpixel repeating group on said display panel to both said first and second viewing windows, the third column having the alternating pattern of the second and third primary colour subpixels (2416, 2412), such that when an observer positions left and right eyes in said respective first and second viewing windows, the observer perceives a three-dimensional image.
