TFT displays use switching transistors and capacitors. These tiny transistors control each pixel on the display and require very little energy to actively change the orientation of the liquid crystal. This allows for faster control of each red, green, and blue sub-pixel cell, thus producing clear, fast-moving color graphics. The TFT pixels are divided into sub-pixels capable of producing various intensities of red, green or blue. The mixture of color and levels of intensity allows for an accurate depiction of any combination of 16.7 million colors.
