?[The difference between plasma TV and LCD TV] Which is better, plasma TV or LCD TV
Plasma TV
Also known as PDP TV, it relies on high voltage to activate a special gas in the imaging unit, so that it generates ultraviolet rays to excite phosphorescent substances to emit light. Plasma TV completely eliminates the phenomenon of picture shaking, and high definition, will not cause visual fatigue and damage to the eyes. At the same time, in theory, plasma can achieve an unimaginably large picture. With this technology, you can enjoy the theater effect even at home.
LCD TV
Also known as LCD TV, it uses current to change the structure of the crystal in the thin film transistor on the liquid crystal panel to make it develop. LCD TVs have many features, such as rich colors, up to 16.7 million colors, the current resolution of LCD TVs over 32 inches can reach 1366*768 or more, and most of them support 1920*1080 resolution; LCD TVs have longer use. Life, the life of the general LCD TV is about 50,000 hours.
1. Differences in appearance
LCD TVs are thinner than plasma TVs, especially the latest TVs with LED backlights , even less than 1 cm thick, plasma TVs are slightly stronger in appearance than LCD TVs. With the continuous updating of technology, LCD TVs have appeared borderless TVs. Such TV products are stylish, slim and more competitive in appearance. Although the design of the plasma TV has also changed, in general, it is still a bit heavy.
2. The difference in price
Currently on the market, plasma TVs are slightly more expensive than LCD TVs, but plasmas look more comfortable than LCDs. Brightness is not as high as LCD, so dazzling. LCD TVs have different functions, different models, and different prices. In particular, the price of new models is high, and there are very few large-screen LCD screens made in China, and almost all of them are imported. It also depends on the level of the screen. There are price differences here.
3. Differences in viewing angle
Due to the different lighting principles, although the viewing angle of plasma and LCD TVs can reach 170 degrees, LCD TVs are When viewing at a large angle, the picture will have a color cast phenomenon, but the plasma does not have this problem. Therefore, when the whole family is watching together or the living room area is large, plasma TV is more suitable.
In general, LCD TVs and plasma TVs have their own advantages and disadvantages. The body of LCD TVs is thinner, especially some of the latest TVs with LED backlight, the thickness is even less than 1 cm, the power consumption of LCD TVs is relatively small, and it is more power-saving than plasma TVs of the same size. There is more or less light leakage, and it is especially clear in a completely dark environment.
Compared with LCD TVs, plasma TVs are better in terms of image layering, especially in the performance of black scenes, LCD TVs are completely incomparable with plasma TVs. The dynamic definition of LCD TVs is not high, which is mainly determined by the limited deflection speed of liquid crystal molecules, so LCD TVs will appear tailing. Due to the working principle, plasma TVs have higher resolution than LCD TVs. Dynamic definition, for sports games, action movies and other high-speed motion pictures, the performance is smoother, and there will be no smearing phenomenon.
Which is better, LCD TV or plasma?
1. Service life
The initial standards for plasma TVs and LCD TVs are mostly 25,000 to 30,000 hours. The lifespan of plasma screens has reached 60,000 hours. With the development of technology, the lifespan of plasma TVs may be further improved. LCD TVs are also exploring new light source technologies such as LEDs to extend their lifespans.
2. Performance indicators
The nominal brightness and contrast ratio of plasma TVs are higher than those of LCD TVs, and the nominal contrast ratio of plasma TVs is basically 3000: 1. 4000:1 and 5000:1, the latest has reached 10000:1, the brightness is mostly 500cdm2~1000cdm2; the contrast index of LCD TV is basically between 400:1-12001, the brightness is mostly 400-800cmm2, only from 400:1 to 12001. In terms of nominal indicators, plasma TVs are higher than LCD TVs, which is believed to be the origin of the statement that the performance of plasma TVs is better than that of LCD TVs.
3. Display effect
Plasma TV images have a stronger sense of pixels, especially those with a resolution of 852×480, while LCD TV images are more Delicate; in terms of color, the colors of LCD TVs are generally bright and saturated, and some are warmer. Plasma TV’s colors are more natural and fresh.
4. Resolution
Some people say that the resolution of LCD TV is higher than that of plasma TV, this statement is not accurate, from the current market Looking at the products above, plasma TVs do have a number of products with a resolution of 852×480, but at present, plasma TVs with 1024×768, 1366×768 and 1024×1024 resolutions have appeared in the market, whether for computer image display or high-definition Video displays all do the job well. The resolution range of LCD TVs on the market is relatively wide, ranging from 640×480, 1024×768, 1024×768, 1280×768 to 1920×1080.
5. Power consumption
In terms of power consumption, plasma TVs are indeed higher than LCD TVs. At present, most plasma TVs on the market have nominal power consumption They are all in the range of 300W~400W, and LCD TVs rarely exceed 200W.
6. Eco-friendly
LCD TVs are truly eco-friendly TVs without any radiation, while plasma TVs have UV radiation.
Summary: Under the current market conditions, experts suggest that consumers can consider LCD when buying small-sized flat-screen TVs, while large-sized flat-screen TVs have the more obvious advantages of plasma.
A small reminder: Plasma TVs are in decline these days. Plasma TV market acceptance is not high. Market sales are poor, and market-oriented manufacturers reduce production or change the plasma TV production line to other product lines. The plasma TV industry is shrinking and the market share is declining. In contrast, LCD TVs continue to make breakthroughs in technology, manufacturers continue to increase investment, and the market response is also very good.
With the delisting of plasma TVs, the products discontinued by manufacturers, such as plasma TVs, may be recommended by the maintenance personnel to replace or purchase new models in the event of lack of replaceable parts. In this regard, the industry suggested that consumers should be cautious when buying plasma TVs, and manufacturers should also do a good job of after-sales service.
