Understanding Plasma Technology
To grasp the concept of why these televisions are named plasma, we must first dive into the fundamentals of plasma technology.
What Is Plasma?
Plasma is one of the four fundamental states of matter, alongside solid, liquid, and gas. It is formed when a gas is energized to the point that electrons are stripped away from atoms, creating a mixture of ions and free electrons. This state is commonly seen in various environments, such as stars (including the sun), neon lights, and fluorescent tubes.
When it comes to plasma TVs, this state of matter plays a critical role in how the television generates images.
How Plasma TVs Work
Plasma televisions consist of two panels of glass sandwiched together, with a thin layer of gas between them. This gas is typically a mixture of noble gases, such as xenon and neon. The working of a plasma TV can be summarized in the following process:
Electrical Excitation: When an electrical current is applied to the gas in the panel, it becomes ionized. The ions in the plasma state produce ultraviolet (UV) light.
Phosphor Coating: The interior glass panel is coated with phosphor – a substance that fluoresces when exposed to UV light. The UV light emitted from the plasma excites the phosphor, causing it to emit visible light.
Color Creation: Plasma TVs typically use three primary colors: red, green, and blue (RGB). By varying the intensity of these three colors, a plasma TV can create a wide range of colors for the projected image on the screen.
This direct control of individual pixels results in stunning picture quality, deeper blacks, and vibrant colors, which have been a hallmark of plasma technology.
