Understanding Plasma TV Technology

Plasma TVs are thin, bright, and sharp, replacing older TV models. The largest plasma TV is 103 inches. The first plasma screen was invented in 1964, showing only blue. It took 35 years to develop full-color sets. Plasma TVs work by exciting neon and xenon gases between glass layers, creating colored light for images.
