TV, Videos & Audio
What is the difference between a LCD TV and a Plasma TV?
LCD and plasma TV both are looks same, but it has some difference in it. Outward looks are definitely deceiving when it comes to LCD and Plasma TVs. Appearance has similarity in both TV. Used technology in the display screen has difference in the both screen.
Plasma and LCD TVs both are thin and flat and could also incorporated a number of the same features and product benefits. Both kinds can be wall mounted and might supply the internet and local network streaming, both offer the exact kinds of physical connectivity choices, and of course, both permit you to watch TV programs, videos, and other content in a number of display sizes and resolutions.
However, the picture quality on the both TV’s are different. How they display those video visuals is truly quite different. Branded Plasma TV makers are always come out with innovations in picture quality. Samsung Plasma TV is the most selling brand in the plasma category.
Branded Plasma TV an Overview
Plasma technology is an innovative technology used to reflect florescent reflection on the display screen. It’s known in the local market as display light bulb reflective technology. For high quality visual impact branded plasma TV’s are display consists of cells and quality display cells are the main function area in plasma display.
Within each display floroplasma cells multiple cross glass panels are separated by a small narrow-line gap inside which includes and florescent insulating layer, address electrode, and screen electrode, where neon-xenon gas surface is injected and sealed in plasma shape during the plasm TV production line procedure.
When a Plasma TV is in the working mode, the cell gas is electrically charged at particular intervals. The gas strikes red, green, and blue phosphors produce visually high-quality image. RGB display type of red, green, and blue phosphors is called a pixel, that’s more display quality. Because of how Plasma technology functions, it could be made quite thin. However, although need for the bulky image tube and electron beam scanning of these older CRT TV is no longer required, Plasma TVs still use the burning of phosphors to create an image.
Therefore, Plasma TVs still have problems with some of the drawbacks of conventional CRT TVs, such as heat generation and potential screen-burn of static pictures.
LCD TV Overview
LCD TVs are on the other hand, use another method of technology. LCD panels are the main difference in the LCD TV compare to plasma TV. LCD tv display panels are made of 2 layers of translucent material, which can be polarized, and therefore are "glued" together.
One of those layers is coated with a special polymer that holds the person liquid crystals. Current is passed through individual crystals, which permit the crystals to block or pass light to create images.
LCD crystals do not create their own light, so an outside light source, such as fluorescent (CCFL/HCFL) or LEDs are necessary for the image made by the LCD to become visible to the viewer. Presently (2014 moving forward) almost all LCD TVs utilize LED light sources rather than a fluorescent light source.
Unlike standard CRT and Plasma TV, as there are no phosphors that light up, less electricity is required for operation and the light source in an LCD TV generates less heat than a Plasma or CRT TV. Also, due to the nature of LCD technology, there's absolutely no radiation emitted from the display itself.
The Benefits of Plasma over LCD comprise:
Better contrast ratio and capacity to render deeper blacks.
Better colour accuracy and saturation.
Better motion tracking (little or no movement lag in fast moving pictures because of the usage of Sub Field Drive Technology.
Wider side-to-side viewing angle.
Plasma vs LCD Includes Disadvantages.
Plasma TVs aren't as bright as most LCD TVs. Plasma TVs work better in a dimly lit or darkened room.
Display surface is much more reflective than most LCD TVs. More prone to glare - display surface reflects ambient light sources.
Plasma TVs are more vulnerable to burn-in of static pictures. But this problem has diminished greatly in recent years as a consequence of the incorporation "pixel orbiting" and associated technologies.
Plasma TVs create more heat and use more energy than LCD TVs, because of the requirement to light of phosphors to produce the images.
Doesn't work as well at higher altitudes.
Potentially shorter display life span - that was true. Early Plasmas had 30,000 hours or 8 hrs of seeing per day for 9 decades, which was less than LCD. But, screen life span has improved and 60,000-hour life rating is now common, with a few sets ranked as large as 100,000 hours, because of technology improvements.
Advantages of LCD TV over Plasma TV include:
No burn-in of static pictures.
Cooler running temperature.
No high altitude uses difficulties.
Greater image brightness over Plasma, making LCD TVs better for viewing in brightly lit rooms.
Display surface on most LCD TVs is less reflective than Plasma TV screen surfaces, which makes it less vulnerable to screen glare.
Lighter weight (when comparing same display sizes) than Plasma counterparts.
Now, although display life was a variable
For 3D, with LCD you've got a choice between units which use Active Shutter and Passive Glasses, whereas 3D Plasma TVs only use the Active Shutter Glasses system.
Disadvantages of LCD vs Plasma televisions include:
Lower actual contrast ratio, not as great rendering deep blacks, although the increasing incorporation of LED backlighting has narrowed this gap.
Not as good at tracking motion (fast moving objects can display lag artefacts) - But this is improving with the recent implementation of 120Hz display refresh rates and 240Hz processing in most LCD sets, but that may lead to the "Soap Opera Impact", where film-based content resources seem more like videotape that picture.
Narrower effective side-by-side angle compared to Plasma. On LCD TVs, it's normal to see colour fading or colour shifting as you move your viewing position farther to both sides of the middle point.
Although LCD TVs don't suffer from burn-in susceptibility, it's likely that individual pixels on LCD televisions may burn, causing small, observable, black or white dots to appear on the screen. Individual pixels can't be repaired, the entire screen would have to be replaced at the point if the person pixel burnout gets annoying to you.
LCD TV is generally more costly than equivalent-sized (and equal featured) Plasma TV, even though that is no longer a variable, now that Plasma TVs are discontinued.
The 4K Element
1 additional issue to point out with respect to the difference between LCD and Plasma TVs, is that when 4K Ultra HD TVs were introduced, TV makers made the decision to just make 4K resolution on LCD TVs, using LED back and edge-lighting, and, in the case of LG, additionally incorporating 4K to TVs using OLED technology.
Though it's technologically feasible to manufacture and integrate 4K resolution display capability to a Plasma TV, it's more costly to do so than on an LCD TV platform, and, together with the earnings of Plasma TVs continuing to decrease through time, Plasma TV made a business decision to not attract consumer-based 4K Ultra HD Plasma TVs to advertise. The only 4K Ultra HD Plasma TVs which were/are manufactured are strictly for industrial application usage.
