Pixel geometries for LCD display: subpixels are arranged with patterns alternating rows with RBG and GBR order. This is one of the alternative layouts to classic RGB (or BGR) layouts, that allows increasing the horizontal resolution of black and white vertical stripes without creating color fringes (which become visible only when they cover a distance of several pixels aligned vertically).

• With a classic RGB or BGR layout, the thinnest and fringeless B&W stripes must use white strokes covering all three subpixels equally, creating a pattern whose width is 6 subpixels.
• With this layout, it is possible to display both the black and the white stripe within 1.5 subpixel each, i.e. a total of 3 subpixels for the 2 vertical strokes, in two possible configurations, such as: the vertical white strokes on a black background will fully illuminate a red and green row, and half-illuminate the blue pixels on each side; the vertical black strokes will leave the next red or green column black and will half-darken the blue pixels on each side.

This layout would be ideal for small LCD panels of smartphones, where the pixel density cannot be easily increased to keep a good contrast (notably for outdoor use), where the total resolution is necessarily limited as well as the distance of observation which makes the individual pixels more visible.

This layout is currently experimental as it is still not supported by ClearType and Quartz subpixel renderings used in Windows and MacOS X. Note that the blue subpixels are vertically aligned and could still potentially produce bue color fringes, but choosing blue is preferable as it is the pigment that contributes the least to the visual intensity.
