First to look at is the contrast ratio/ black level. It is a measure of the blackest black compared to the whitest white. Both plasma and LCD TV are very competitive in this field. Their qualities are closer than a year a go, but plasma still leads in the business. Plasma TV uses most power when it produces full white. This causes a humming sounds when displaying white or very light images. On the contrary, LCD TVs use most power when displaying dark or black image. This leads to off axis viewing when black levels consistently drop. This is why Plasma TV still consistently does better than LCD TVs for scenes with a lot of dark and light images shown simultaneously such as content originating from DVDs, video games, and NTSC TV signals. For color accuracy, plasma TV is more preferable, but it is depends on the room light. Plasma sends color information that is more accurately reproduced. It has more natural coloration. LCD technology is not as impressive as plasma with similar pixel counts. LCD produces a brighter picture. Greens are sometimes looked over green and reds can run a bit warm. This make LCD TV outperform plasma in a room with bright outdoor lighting whereas plasma will do better in rooms with lower to normal lighting. Plasma has done better for the viewing angle. It has 160o viewing angles. This is about as good as horizontal and vertical viewing angles get. This make plasma is definitely performs better than LCD with only 120 to 130 degrees viewing angle for the best LCD TV. This is back again to a leading performance of plasma in displaying dark material contents especially DVDs. Black level from off axis usually occurs after around 90o. This causes LCD can not help much because it loses black level intensity more as the angle of axis increases. · Function considerations This is the simplest consideration in choosing between plasma and LCD TV. For computer use, LCD is better than plasma. It is because LCD flat screen is extremely well in displaying static images from computer or VGA sources. It has full color detail, no flicker, and no screen burn-in. LCD monitor is also has good specification in displaying large amounts of data with exceptional clarity and precision. This helps you in doing Excel well. LCD TVs is also slightly better model for video gaming. Those advantages are caused by the higher number of pixels per square inch on an LCD display than other display technologies. On the contrary, some plasma models, for example EDTV plasma, do not handle a computer input well and produce a very rough image when viewing static images from same. But, for the fast-moving video playback function, plasma has done a better job. It is because it has an excellent performance with fast-moving images and high contrast levels. In displaying the fast moving sports scenes, LCD still has a slight motion response lag that can be detected by the most discerning eyes. For a high altitude function, LCD is more preferable. It is because LCD TVs are not affected by increases or decreases in air pressure. They have a consistent performance no matter how high at which they are utilized. This is why LCD flat panels are preferably used on airplanes for visual display units. Plasma is more influenced by the air pressure. At high altitude (6,500 feet and above), lower air pressure can cause plasma display emits a buzzing sound. For general, both have the same quality in durability. This aspect depends on manufacturer quality. · Other considerations Both plasma and LCD TV are available in larger size although plasma still wins the size battle because of its great margin. The super duper 100" big screen of plasma has been produced while the biggest LCD screen has been produced is only 45”. LCD is still difficult to be produced in large size without pixel defects owing to faulty transistors. This is due to its substrate material. But a very large LCD screens can be produced if production goes as planned. The smaller screen available now does not make LCD lost in the battle. LCD TVs have been proven can save much energy than plasmas do. LCD TVs consume about half the power that plasma displays consume. It is because plasmas use a lot of electricity to light each and every pixel seen on a screen, even for the dark ones. For the same size display, plasma TV consumes three times more power. But for general, both have a fair shake in price and resolution.

At first, we need to know about both different technologies at the basic level. Both actually have a very different way in delivering the image to the viewer. Plasma technology consists of individual pixel cell in hundreds of thousands amount. These individual pixel cells 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. On the other hand, LCD technology consists of a matrix of thin-film transistors (TFTs) supplies voltage to liquid-crystal-filled cells sandwiched between two sheets of glass. LCD monitors reproduce color through a process of subtraction. They block out particular color wavelengths from the spectrum of white light until they are left with just right color. This basic different technology make both have each specification and advantage. Here are some consideration aspects to compare each advantage:BizRate's Special Offers
