LCD
A liquid crystal display (LCD) is a thin, flat display appliance made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. It is prized by engineers because it uses very little amounts of electric power, and is therefore suitable for use in battery-powered electronic devices. In color LCDs each individual pixel is separated into three cells, or subpixels, which are coloured red, green, and blue, respectively, by additional filters. Each subpixel can be controlled independently to defer thousands or millions of possible colors for each pixel. Older CRT monitors employ a similar sub pixel structures via the use of phosphors, although the analog electron beam employed in CRTs do not hit correct subpixels.
Color components may be arrayed in a range of pixel geometries, depending on the monitor's usage. If software knows which type of geometry is being used in a given LCD, this can be used to increase the evident resolution of the monitor through subpixel rendering.
