About LCD Screens and Plasma Screens, Flat Panel Display

The continuing development of LCD screens.  Most people are familiar with an LCD screen, because laptop computers have used them for several decades. The immediate characteristics you notice is the thinness of these screens  compared to the traditional desktop CRT computer screens. LCDs have developed to become desktop or arm-mounted computer monitors and also a technology used in designing television sets. LCDs eliminate screen curvature, allowing them to be dubbed flat screen, and the 1" to 4" inch thick monitor body-type fits them into the category known as flat panel display.

Flat panel plasma screens provide a viewing screen measuring up to 60" diagonal. Considered the "coolest" television by many consumers, plasma technology has allowed screen size to  expand. Available in flat screened sizes from the mid 30" models up to 60", these bigger plasma panels can come in HDTV, high definition television. Their body types are from 3" to 6" deep, which allows them to also be termed flat panels. Plasma monitors can also be used as computer monitors as well as television screens.

How do plasma screens work? A plasma screen is able to deliver a more detailed screen image than LCDs and the traditional CRT televisions, because of the very large quantity and extremely small size of phosphor cells that are foundational to this technology.

Inner workings of flat panel plasma. Every pixel (sectioning) in the screen contains a red, green, and blue phosphor cell that may be filled with either neon or xenon gas. There may be over 980,0900 pixels in a 50 inch screen plasma, for example. This gas in each colored cell changes into a plasma state when an electrical current passes through them, causing them to emit an ultraviolet light; that light, in turn, causes the phosphor material in each cell  to emit combinations of the red, green, or blue light that forms images.

Care must be taken to protect the display screens from damage. Crushed pixels will render sections of the screen un-viewable.

Why might you select plasma? An expanded list of advantages and disadvantages are noted below, but what are three primary reasons someone might be attracted to purchasing a plasma screen display? (1) A desire to watch television on screens larger than 37"; (2) Clear, colorful, and responsive video images; (3) When several people or a group will be watching the set because the wide viewing field allows clarity at angles.

How do LCD screens work? There are five layers within an LCD display: a backlight, polarized glass sheet, a layering of colored pixels, a coating of liquid crystal solution, another sheet of glass. Each pixel contains cells filled with liquid crystals (red, green, and blue cells). Voltage off thin film transistors (TFTs) power the red, green, and blue cells to untwist and allow measured amounts of light to shine through them and form images.

Because light always has to pass through an LCD chip to create an image and because LCDs, unlike plasma screens, do not create their own light source, it is impossible for LCD monitors to produce a true black; instead, it will show up as dark shades of gray. Straight viewing is the best angle for viewing LCD images, because as you move to either side, image quality diminishes and, as the angle increases, the image disappears.

LCDs are manufactured as both computer monitors and television screens. It is proper to call them flat panels because of their thin depth of only a couple inches. Their lack of screen curve may be referred to as flat screen, as well, but they are most suitable to be called "flat panel." Their light build enables them to be mounted conveniently.

Why might you select an LCD? (1) LCDs are excellent as computer screens, because those images are static, compared to video images which can create a jagged "image delay" appearance; Most particularly, it’s often recommended that when you will be using your screen for dual video and computer use, you consider purchasing a LCD TV with a computer input, rather than a LCD computer screen with a tuner. (2) When few people in a contained area will be watching the LCD television, to ensure viewing is from "straight-on." (3) LCDs allow you to enjoy more accurate and vibrant color.

Care must be taken with your LCD screen, which is also true for plasma screens, in order to protect them from damage. Crushed pixels render sections of the screen completely un-viewable.

Mounting your LCD and Plasma screens. Their thin design takes up less desk or floor surface area. You can hang LCDs and plasmas  from a wall, ceiling mount them, attach them to articulating arms, or place them on desk mounts or floor stands or even cabinets designed to meet your office or home decor. Not all mounting devices fit both LCD screens and plasma screens, but Ergo In Demand has complete mounting solutions that manage your viewing placement effectively and attractively.
