Here’s a quick excerpt
For a layman, there seems to be no difference between a plasma and LCD TV. Both provide high-resolution, high-contrast images and both are flat, sleek and can be mounted on a wall. The difference lies in the technology that drives them.
Plasma TVs work with inert gases like xenon or neon, which are excited by electric pulses from specialized cells called pixels. This makes the gases glow. These glowing gases, in turn, produce the correct blend of red, blue and green light on the pixels. The pixels are illuminated by a fluorescent light bulb, which is driven by semiconductor software on the motherboard.
LCDs are actually thin film transistors (TFT), which contain liquid filled crystals between two plates of glass. LCDs work by blocking out unwanted light. When the signal hits the TFTs, they contort to a required angle, thus allowing only the requisite amount of light to pass through. A lamp […]
