Principle and classification of flat-panel TV

Flat screen TV, as its name implies, is a TV that looks like a flat screen. At present, there are two kinds of plasma color TV and LCD color TV, but the principles are completely different, so the prices are also very different.

plasma display panel (PDP)

Plasma is the principle of using countless small inert gas bulbs on the screen to form images. Due to the limitation of this principle, plasma TV cannot be made too small, usually more than 40 inches. Compared with LCD TV, it is cheaper and has poor definition. The thickness of plasma TV is usually around 10 cm.

LCD color TV

LCD TVs use the same display technology as flat panel displays of notebook computers and desktop computers. Its vivid picture is produced by an expensive special glass panel and transistors on it. Like plasma TV, TV is very thin.

Classification of flat-panel TV

At present, LCD (liquid crystal display), PDP (plasma display) and organic light emitting diode (OLED display) have become the three pillars of flat panel display. Digital light display rear projection TV is actually a kind of rear projection TV. The old rear projection TV was larger, but this new generation of rear projection TV uses digital technology and has a lighter shape. The special chip at the back forms an image, which is simpler than the screen of LCD TV and plasma TV.
