Photographs of various displays, showing various pixel geometries. Clockwise from top left, a standard definition CRT television, a CRT computer monitor, a laptop LCD, and the OLPC XO-1 LC display.
The 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 monitors, such as LCDs or CRTs, that typically display edges or rectangles, the components are arranged in vertical stripes.
