RGB System

Colours on the television screen are created by a special form of additive light mixture known as a partitive mixture. The surface of the screen is covered by tiny points, each with a diameter of approximately 0.2 mm, containing phosphorescent materials (molecules). Normally, three types are selected to transmit red, green or blue light after excitement by beams of electrons; in other words, after they have absorbed energy. The screen colour-system introduced here is named RGB after these three colours. (Detailed text)
