LCD Display

Graphical LCD liquid crystal display is a display which allows displaying pictures and text. Its construction is similar to the alphanumerical LCD, with a difference that on the graphic display all pixels are divided as one large matrix. If we are dealing with a monochrome LCD, then a pixel is one square segment. Color displays’ one pixel is formed of three subpixels. Each of the three subpixels lets only one colored light pass (red, green or blue). Since the subpixels are positioned very close to each other, they seem like one pixel.
