- General features include operation from standard power sources worldwide and direct analog connect video (VGA, SVGA, VESA) without special drivers or modifications.
- In recent years, two main types of LCDs have emerged: Super Twisted Nematic (STN) and Thin Film Transistor (TFT) displays.
- The liquid crystal display is a non-emissive display device. It does not produce light like a CRT monitor that we usually found in desktop PCs.
- The LCDs available on the market can support up to 256 thousand colors.
- An LCD is a mixture of layers of glass and liquid crystals, modern electronic circuitry and a background lighting source.
- The liquid crystal layer is then surrounded by two additional layers of glass, known as polarisers, which possesses a unique quality of only passing light if it is oriented in a specific direction.
- The integrated circuittry (IC) address the individual pixels by applying a voltage to that area to stimulate a reaction in the liquid crystals. This reaction causes the liquid crystal to either pass or block light coming from the display's light source, thus creating the image we see on the screen.
- Color is produced by adding a layer of color filters, which is comprised of three sub-pixels, each corresponding to the colors red, green and blue (RGB).
