The Differences between LCD and Plasma Tvs

The differences between LCD TVs and plasma TVs are like night and day. While many of you know that LCD and plasma differ. Some of you may not know how exactly they differ. There are the obvious trait differences which you can see simply by looking at the screen, and then there are those not so obvious differences, which go beneath the casing and the glossy surface screen.

While they may both look nearly identical on the surface other then slightly different picture displays. They are really very different inside, the technology which is used to manufacture them is completely different.

In an effort to not get too technical, but give you an idea how these technologies vary, let’s start with how they are built.

LCD TVS have a solid sheet of glass with pixels placed inside the glass. Each pixel has a conductor which runs through the entire glass pane and out the end. Each one of these wires registers a different amount of voltage based on the color to be displayed, and this shuts out other colors. Behind this glass pane you will find a couple of florescent lights which shine through the pane to light up the screen. Without this back lighting the image would be invisible as in effect the glass pane is sort of like a stained glass. The colors change but there is no light generated inside.

Plasma TVs have gas and phosphors burning inside them. These phosphors dependent upon how much voltage is applied generate light, the color of the light varies based on gas pressure and electrical charge. This is all contained in between two glass sheets. A plasma screen is not a solid unit, and due to the design it has it’s flaws. It is more likely to be broken then an LCD screen and any fracture will release the gas which is required to generate light.

Basically LCD (Liquid Crystal Display) and plasma are very different even though the boxes they are held in look the same. The differences in technology include gas VS fluorescent, phosphor VS liquid crystal, and solid structure VS contained structure. In picture results and the obvious differences there may seem to be none. Plasma screens have more glare and break easier. LCD screens reduce glare, are difficult to break, and have a slimmer viewing angle due to the technology of the screen the light is only projected through the glass up to a certain degree straight forward.
