In the creation of digital signage there is a debate about which display option is best - LCD or plasma.

There are several factors summarized here, including performance and cost, that will determine whether you choose LCD or plasma for your digital signage display.

The Mechanics

A January, 2007 article on selfserviceworld.com described the differences betwixt LCD and plasma in layperson's terms. In summary:

• LCD consists of two sheets of transparent, polarized material, one of which is treated with a polymer liquid crystals. The crystals interpret the electric current and control the airy that passes through. Fluorescent tubes the crystals perform the subtile that passes out to the viewer. The crystals do not emit weightless so LCD screens use at the bottom electricity than other displays.

• Plasma displays use glass coated with bubbles that contain ionized gas in red, blue, and olive subcompartments. A phosphorescent coating is applied to the glass and when electricity passes through the plasma it emits ultraviolet rays that show the appropriate color.

Performance

An oft-cited concern with plasma screens is burn-in. Depending on what you read, burn-in is either a serious problem or a minor one that can be remedied.

Burn-in is a term used to set forth static images that become permanently in view behind being displayed for a certain number periods of time. Burn-in is not an issue with LCD displays but can become a problem with plasma. Burn-in is becoming below average of an issue as digital signage display firms employ some homely techniques for wild it: ensuring images are frequently rotated, using more motion, and dip contrast and brightness levels.

Lifecycle is another concern. At one time LCD had a longer life, but the life expectancy of LCD and plasma are now roughly equivalent, lasting about 50,000 hours each.

LCD units are lighter and use below average power, factors which may affect your decision.

Contrast ratios (the difference amongst black and white) are much higher on plasma, which results in a clearer and brighter image. Plasma displays video images and speedy flow better than LCD and offers a wider viewing angle, which can be important in retail environments.

Cost and Size

The deciding factor amidst LCD and plasma has oftentimes been cost. With the prices of large-format LCD displays dropping, cost is becoming underADJ Expensiveness of an issue.

Size is an issue that ties in with cost since it is your budget that may ultimately determine the greatness of screen you choose. Plasma is generally available in larger sizes, against this is changing as LCD displays get bigger. Plasma does still tend to win out for larger displays - digital signage display designers tend to prefer it for displays over 50 inches.

How Can You Decide on a Digital Signage Display Format?

Both LCD and plasma motion some benefits, depending on your needs. When making a decision about your digital signage display, you need to take a weal look at your budget and factor in the dimension of the display required
