Hello everyone, Lin Fei to answer the above questions, plasma TV schematic, what is plasma TV many people do not know, now let's take a look at it!

With the improvement of our quality of life, people more and more know how to enjoy, which can be seen from the development of television. In terms of broadcast content, from cable TV to the current network TV; in terms of display, it has also developed from the initial rear projection TV to second-class plasma TV and LCD TV. But many people may not know much about plasma TV and LCD TV, nor do they know the difference between the two. Today, Benshaw will introduce the difference between plasma TV and LCD TV in detail.

Image quality:

At present, the contrast of plasma is mostly 3000: 1, 4000: 1, 5000: 1, or even as high as 10000: 1, while the contrast of LCD TV is basically between 400: 1 and 1200: 1. In the well-lit environment such as the store, the picture of the LCD TV will be brighter than the plasma, but in the darker environment at home, the LCD will be very dazzling. If the brightness is reduced, the image hierarchy and details of the dark picture will be lost. Compared with plasma, the picture is softer, clearer and brighter. Because the liquid crystal is transparent, the bright part of the picture is brighter, basically losing the detailed image that can be seen on the plasma.

Power consumption issues:

First of all, it should be clear that the plasma TV is a pixel-by-pixel drive circuit, which belongs to pure digital display. It is a kind of liquid crystal digital circuit with analog image display function. In principle, plasma consumes more power. The power consumption of plasma TV is determined by the light and shade of picture pixels, and the liquid crystal is illuminated by more than a dozen fluorescent lamps, which is the principle of "shadow play". On the surface, the nominal power consumption of plasma is larger, but in practical use, compared with plasma and liquid crystal of the same size, the power consumption of plasma is less than that of liquid crystal. This is not nonsense, because it is almost impossible for the picture to reach 100% brightness when watching TV or DVD. The average brightness of the general picture is about 30%, while the power consumption of the plasma is only 30%, 60% of the nominal value. But LCD is different, the brightness of the picture does not affect the power consumption. All bright and all black fluorescent lamps have 100% brightness. Rated power at any time. The nominal power of the two plasma is larger, but the plasma power consumption is smaller in use, or the power consumption of the two is very close. The test results show that when watching TV, the power consumption of 42-inch plasma varies from 100 W to 320 W, while the power consumption of 40-inch LCD is always 280W.

The question of lifespan

Because the LCD tube is in a bright state, the screen brightness drops to 70% after 5000 hours, and then enters a stable period. However, when the light changes to a yellow cycle, the image has a yellow feeling. There is little chance that the plasma's self-illuminating pixels will be at 100% brightness, and the pixel brightness will drop by about 5% after 10000 hours. Nowadays, industrial monitoring requires 24-hour work on many occasions, and plasma is the main task. Some data show that the plasma displays used by some units in 1997 are still working normally, and the start-up time has exceeded 73000 hours. If the LCD is replaced, even if the LCD panel is not damaged, I do not know how many lights have been changed!

In terms of energy consumption, as the power of the 42-inch flat panel TV is about 300W, it should not be our concern. Birthday faces take only 20000 hours, at least 20 years for the family.

After reading the above introduction, I think you already know the difference between plasma TV and LCD TV. The two are different in terms of picture quality, life, price and so on. Bian Xiao believes that if it is for home use, choose LCD TV, if it is public, you can choose plasma TV. LCD TV has high quality, good eyesight and good look and feel, so it can be put at home. Moreover, LCD televisions are expensive and uneconomical to use in public places, because televisions in public places are difficult to protect, so the degree of damage may be very high.

At the end of this article, I hope it will be helpful to you.
