Subpixel rendering is a method used to increase the effective resolution of a color display device. It utilizes the composition of each pixel, which consists of three subpixels of which are red, green, and blue that can each be individually addressable on the display matrix.

Subpixel rendering is primarily used for text rendering on standard DPI displays.

Despite the inherent color anomalies, it can also be used to render general graphics.
