Search the web, LCD vs plasma info is all over the web.
They are two totally different ways of getting a great picture. Plasma uses a gas, usually a combo of neon and xeon gases, sandwiched between two glass panels. The gas is excited by electricity and changes colors to display the picture. LCD = Liquid Crystal Display. The screen is made up of many, many little cache pots with a liquid in them. This liquid is excited by the electricity and then turns colors and displays your picture.
Contrast ratio gives you the shades of a color from darkest to lightest. This gives you more detail, shading in the picture. Plasma is just capable of displaying more contrast ratio than LCD. Plasmas give you those wonderful rich colors with lots of detail (that’s the higher contrast ratio) than LCD. Especially dark colors. Many LCD units will make the dark color much flatter and have less texture than a plasma. Some LCD units won’t pick up on the fact that a suit has a white pinstripe in it or there are light colored textures in a background and will report them as a solid color.
LCD’s run at either 60hz, 120hz or 240hz. Hz is how many times per second the picture can be refreshed to clearly show fast action. Plasma runs at 600hz. You will pay more for a 240hz LCD because it’s the latest and greatest technology. Plasma costs less to buy because it costs less to manufacture.
Both technologies are long lasting, energy efficient and maintenance free. Buying a quality unit in either technology is key to long life and good picture quality. But that does not mean you have to spend big bucks! There are quality budget friendly units available! Either technology is good for gaming but plasma will give you better textures and performance.
Your deciding factor may be size of the unit. Plasma does not come in sizes under 42″. And it’s difficult to find a LCD unit that is 120hz below 32″. Forget about finding 240hz units in that size. And many of the small LCD units are 720p also. In the smaller screens, you don’t see the difference. A good budget stretcher is a 720p Plasma. Their picture quality is still amazing, you get the same performance. But IF you are considering going PS3 or Blu-ray, get a 1080p unit. PS3/Blu-ray puts out 1080p signal to give you that amazing movie or gaming experience and in order to get the most out of that investment, you should match the TV to the unit.
For some info on some of these technologies in a well written format, try checking out hdguru.com. He throws enough techie info to keep those of us in the “business” amused but doesn’t make it so complicated that the general public has trouble understanding.
plasma more deep and little bright …and has not back light problem like cloud or flash light
lcd brighter than plasma …this is the main thing i guess
simply lcd is similar to a studio light box that has a a diffuser in front of the light so even it out over the entire screen. this light never turns off thats why there are no true blacks. the liquid twists to block out the light.
Plasma flat screen technology consists of hundreds of thousands of individual pixel cells, which allow electric pulses (stemming from electrodes) to excite rare natural gases-usually xenon and neon-causing them to glow and produce light. This light illuminates the proper balance of red, green, or blue phosphors contained in each cell to display the proper color sequence from the light. Each pixel cell is essentially an individual microscopic florescent light bulb, receiving instruction from software contained on the rear electrostatic silicon board. Look very closely at a plasma TV and you can actually see the individual pixel cell coloration of red, green, and blue bars. You can also see the black ribs which separate each.
Keep in mind that although plasmas have true blacks they lack true white because they brighten the colors to the point where the light outshines the color. the downside to this is this increases your electric bill. in simple terms. Lost in Space movie will cost less to watch then March of the Penguins. finally if you ever get burn-in on your plasma simply turn the tv off for 5-7 days and it will fade away over time.
