Pixel geometry
\nThe
components of the
pixels (
primary colors red, green and blue) in an
image sensor or
display can be ordered in different
patterns, called
pixel geometry.
The
geometric arrangement of the
primary colors within a pixel varies depending on usage (see figure 1). In
monitorss, such as LCDs or
CRTss, that typically display edges or rectangles, the components are arranged in vertical stripes. Displays with
motion pictures should instead have triangular or diagonal patterns so that the image
variation is perceived better by the viewer.

Knowledge of the pixel geometry used by a display may be used to create
raster images of higher apparent
resolution. See
subpixel rendering.
