What is LCD, LED and plasma?The first question that comes to mind is probably what is the difference between the three types of TV? LCD means Liquid Crystal Display. LCD screen LCD, which is activated when an electric current is supplied. Working up LED LCD TV, the same platform, but the light from an LED (Light Emitting Diodes) are used as backlighting for this TV, LCD TV, the lamps during normal use CCFL ( Cold cathode fluorescent lamps). A plasma TV works on a completely different platform. A plasma screen is a single sheet of plasma cells which is triggered when the current is passed to the television program. Read on to learn how to work a plasma TV? So we can see that plasma and LCD technologies are completely different, while the difference between LCD and LED backlight, which they use. Read on and criticisms of the flat-screen TV and the difference between LCD and plasma TVs.
Evaluation of step 1: Contrast RatioContrast ratio is the ability of television to point to areas of high contrast on the screen. Areas of high contrast black and white are the colors of the image. If your TV has a contrast ratio is good, you see the difference between light and dark areas of the screen are very good. Testing the contrast ratio is a TV in dark scenes that require the need to distinguish the color black.The fact that plasma TVs have a contrast ratio better generally as LCD and LED. This is because the plasma has a plasma TV in each cell, which activate automatically shares the black screen. LCD TV the other hand, a liquid crystal display so that when it comes to displaying dark images must CCFL mitigated by the black color is not so convincing. On the other hand, supported by LCD televisions with LED rear lights, a slight advantage, because the single LED on the switch "OFF" in the dark as to convince a black screen LCD TV.Results: In the settings of the contrast ratio, plasma TV has a clear top. LED TV is next, followed by LCD TV last year.
The assessment of point No. 2: Viewing AngleThe angle is the angle that the images can be seen on television. To see all the TV when in front of him, but because the audience can not sit around watching TV and had to sit around (left and right), then the point is very important being the parameters.Winner at this point is a new plasma TV. Plasma TV, the picture is still good and solid for the general public in practically every street corner. LCD TVs to fall, when there is often a loss of color and details when the TV is seen in terms of side. LED TV, the problems caused by the LCD TV due to the decentralization of the backlight so that it provides a wider viewing angle to minimize the face.Results: The parameter plasma display TV a winner, a second TV and LCD TV in the head last.
The assessment of point No. 3: ColorIt 'clear that the bright colors of television will be an important factor in the minds of TV buyers. But there are no winners in this setting because all the TV appears to show a good image quality. The differences between the two models can be the same type of television or two different brands of television, there is, the more expensive models show better color, but more of the same image quality. It is said that when the TV is equipped with LED colored lights, will show the best image of all, but is still under discussion.Results: All votes are of good quality TV, which determines the price, the better, because higher prices generally better color screen.
Evaluation of step # 4: MotionLCD TV has shown great improvement in this parameter in the last year, but it can be argued that plasma technology has the advantage of being here. With plasma screens have individual cells that can be upgraded to a much faster rate. Traffic flow has become a scourge for manufacturers of LCD-TV for a while. " LED TV with largely the same technology as LCD TV, but showed a better performance of LCD TVs.Results: Plasma for now, still champion, followed by the TV in the affairs of LED movement.
The assessment described in Step # 5: EnergyPlasma TVs use more energy than LCD TVs, as each sub-pixel on the screen lights up. Conversely, the need for multiple LCD TV has a little power to illuminate the rear wheels. But television is the winner here because the LED rear lights LED power more efficient and have lower power requirements.Results: LED TV is a winner at this stage, followed by LCD and plasma screens.Evaluation Step # 6: LifetimePlasma TV weakness, that the author is trying to solve this problem is age. The quality and brightness of the plasma to a beating in a very short time. But now comes with a plasma output more effectively, which has the potential to last longer. Age of the LED and LCD televisions, age taillights, but it must be the average age of television, better than plasma TVs.Another thing to consider is, over the age of the burn-in (burn). Plasma TVs have problems because it has the potential for burn-in is on a bigger screen. Manufacturers of plasma TVs are trying to fix a solution to this problem. LCD and LED rarely burn problems.Results: At this point, the LCD TV has become the winner, during the lifetime of the LED taillights have not yet been tested, as a relatively new technology. But attempts to extend the life of the plasma in the vicinity of the TV monitor.
Evaluation of step 6: PriceHaving said all that, ultimately, the decision of most people is created by the price tag. For many people around the world, the issue is much more important than the price of the first six points.Over the years, plasma enjoyed a much lower price than LCD, but as a measure of production and increasing demand for LCDs, LCD prices will in future be increasingly competitive with the plasma. LED TV has a high price as a new technology. The small size of the plasma is more expensive, but for now is dominated by large TV Cheap LCD TV.Results: Plasma TV is the number 1 for small (less than 32 inches), but TV over 32 inch LCD is cheaper. LED TV is still worth two times more expensive than LCDs for the same size.
