Do plasma TVs use a lot of electricity?
According to the Wall Street Journal, a 42-inch plasma set can consume more electricity than a full-size refrigerator -- even when that TV is used only a few hours a day. But the WSJ notes that A 42-inch LCD set, a typical upgrade item, requires about twice that amount of electricity.
Plasma TVs have an edge over LCD TVs in terms of overall picture quality but LCDs are catching up with improvements like LED backlighting. The main difference lies in the display technology. Liquid Crystal Displays (LCD) panels - work by trapping a liquid crystal solution between two sheets of polarized glass.
- Plasma TV is a television display technology in which each pixel on the screen is illuminated by a tiny bit of plasma (charged gas). The plasma is encased between two thin sheets of glass. Plasma displays are generally considered to offer better dark-room viewing and wider viewing angles than LCD.
- Though Fujitsu gets credit for producing the first full-color plasma display panel in 1992, it was Philips in 1997 that produced the first plasma television to be sold to consumers – the display was 42-inches diagonally and begged a premium price of $15,000.
- A flat-panel TV is a television set that uses one of several different technologies for display in a flat, thin format. Most new televisions are flat-panel models; older TV sets, which use cathode ray tubes (CRT), are much bulkier. Plasma and LCD are the two most common technologies used for flat-panel displays.
