Chemistry has had a colossal impact on the advancement of technology throughout the world. Every electronic item can acknowledge chemistry for its creation. A main example that everyone knows of would be the television. Without chemistry, there would be no technology; and without technology, we would not be where we are today.

The newer models of televisions contain plasma in their screens. Plasma screens are made up of groups of cells called pixels. These pixels are composed of three sub-pixels that consist of three different colors; green, red, and blue. “This technology uses a plasma etching system which is a type of plasma processing mainly used in fabricating integrated circuits. The process involves shooting a gas mixture of glow discharge or plasma towards a sample at very high speeds.” (The Canadian News). The plasma, in gas state, reacts with phosphors in the television panel’s sub-pixels to create colored light in green, red, or blue. A phosphor is a synthetic fluorescent or phosphorescent substance. The phosphors used are comparable to the ones used in traditional Cathode Ray Tube televisions and computer monitors. Cathode Ray tubes are a high-vacuum tube in which cathode rays produce a luminous image on a fluorescent screen. With plasma technology, televisions are now able to display richer, more dynamic, and more realistic colors than the CRT televisions (The Canadian News). Technology is affecting society in various ways today. The television has an impact on the behavior of adolescents that many would consider negative. For example, violence in media can cause youth violence. According to Brandon S.
