Should you go for the LCD or plasma video display? It depends. Here are a few tips to help you choose.
Picture quality
Plasma displays reproduce color more accurately with deeper blacks and display moving images with remarkable clarity. They provide excellent performance with their high-contrast levels and color saturation, and have the edge when it comes to viewing angles. In fact, plasma screen have as much as 160° viewing angle, whereas LCDs display at 130-140° angles. However, they also carry the risk of image burn-in (the permanent disfiguring of a screen image caused by the continuous display of a high-contrast object).
LCD displays, on the other hand, don’t have quite the color accuracy of plasmas, but they’re brighter and have a sharpness advantage with a higher number of pixels per square inch. These additional pixels make LCD technology better at displaying static images from computers or VGA sources in full-color detail. Applications with large amounts of data and written material display particular well on LCDs. What’s more, there’s no risk of image burn-in.
Durability
With LCD screens, there are essentially no parts to wear out. They last as long as their backlights do, with displays lasting, on average, 50,000-75,000 hours. That’s why LCD screens are especially good for applications such as digital signage or displays that require around-the-clock use.
Plasma screens, however, use a combination of electric currents and noble gases (argon, neon, and xenon) to produce a glow, which in turn yields brilliant color. The half-life of these gases, however, is only around 25,000 hours. The glow they produce grows dimmer over time. They’re also prone to burn-in or ghosting of images, although this is less of a problem with newer models.
