Nyquist–Shannon sampling theorem
Although subpixel rendering increases the number of reconstruction points on the display this does not always mean that higher resolution, higher spatial frequencies, more lines and spaces, may be displayed on a given arrangement of color subpixels. A phenomenon occurs as the spatial frequency is increased past the whole pixel Nyquist limit from the Nyquist–Shannon sampling theorem; Chromatic aliasing (color fringes) may appear with higher spatial frequencies in a given orientation on the color subpixel arrangement.
