Dithering is achieved by alternately driving some pixels in a checkerboard type pattern.

Dithering is performed using a regular or repeating pattern, grayscale effect can then be detected by our human eyes.

Commonly, more advance dithering methods will be adopted in order to generate a better grayscale display.

Different checkerboard patterns and random “NO” pixel in a pattern may be used to avoid any visual side effects.
