Picture Elements (Pixels)
The phosphor on the screen naturally displays the on/off property of binary
- Suitable for one color (B&W) video
- The bits in memory are streamed out on the screen in “raster” order, like a standard TV
For a color display, three (basic) colors of light must be displayed: red, green and blue (RGB)
- Requires three different numbers, e.g. one byte each
- Range of colors is determined by the intensity of each component
- When all three values are at their maximum, the color is white, and when they are at their minimum the color is black
