The Fundamentals: Understanding LCD and Plasma Technologies
Before we dive into the pros and cons of each technology, it’s essential to understand the basics of how they work.
LCD TVs
LCD TVs use a layer of liquid crystals to block or allow light to pass through a matrix of pixels. This matrix is typically composed of three sub-pixels, each responsible for producing red, green, and blue light. By combining these sub-pixels in varying intensities, LCD TVs can produce a wide range of colors. The liquid crystals are controlled by an electric current, which twists or untwists them to regulate the amount of light passing through.
Plasma TVs
Plasma TVs, on the other hand, use individual cells filled with a mixture of neon and xenon gases. When an electric current is applied, the gas ionizes, creating ultraviolet light that excites phosphors to produce visible light. The cells are arranged in a matrix, with each cell representing a single pixel. The intensity of the electric current determines the brightness of the pixel, and the phosphors used produce the desired color.
