A high quality LCD TV? What is the difference between good and bad LCD TVs?

Domestic LCD TV is good,I know Changhong、Skyworth,Good reputation,Hard screen panel,Very credible in terms of quality。

The most important thing to buy a TV is to look at the panel.

I feel that the domestic ones are good,Like Skyworth,Changhong's is not bad,Hard screen panel,Good picture quality,The quality is more credible。

In fact, buying large goods,In addition to considering quality factors,After-sales service is also very important,As far as LCD TVs are concerned,Domestic after-sales service is relatively better,Specific situation,It is recommended that you go to315Consumer electronics complaint network to inquire about it,Compare the details of each brand in after-sales service,I believe it will help you。

Sony's does not recommend using Sony's soft screen, which has a slow response speed and low resolution, and the picture is unstable when playing games.

The choice of LCD TV should put the panel in the first place,As far as I know, the LCD TV with a hard screen panel has been recognized by everyone,The quality is reliable,The dynamic picture can also be clearly expressed。

You get what you pay for. Regardless of national feelings, it is safer to import.

Pros:1Thin and portable, the weight of an LCD TV is about 1 3 of a traditional TV.

2.Rich colors With millions of colors, the picture is layered, and the colors are gorgeous and real.

3.The resolution is large, the clarity is high, and the gap between the liquid crystal itself is thicker, and the image is viewed like a grid. So the best resolution of the LCD screen can generally reach 1024x768

4. Low power consumption, long service life, according to industry standards, the use time of annual power consumption of hours per day, with 30-inch LCD TV instead of 32-inch picture tube TV, each unit can save 71 kilowatts of electricity per year. The lifespan of LCD TVs is generally 50,000 hours, which is much longer than the lifespan of ordinary TVs.

Cons: 1The display is slow and the LCD has a long response time, so it doesn't perform well in moving images.

2.The display quality is poor, and the LCD can theoretically only display 18 bits of color (about 262144 colors), but the color depth of the CRT is almost infinite.

3. The viewing angle is small, and the viewing angle of LCD is relatively small compared to CRT display.

4LCD displays are fragile and susceptible to damage. This makes it more difficult to use and maintain LCD TVs.

Advantages 1) Extremely thin, the thickness of the whole machine is only, only 1 6 of LCD TVs, and the weight is also lighter;

2) The frame can be easily made to 1mm, which brings greater visual effect;

3) With an infinite contrast ratio of more than 1,000,000:1, the black is more pure, and even the hair in the black picture can be clearly displayed;

4) The response time is only 1 5000 of LCD, which is 20 times higher than the limit of human eye recognition (the limit of the human eye is;

5) WRGB four-color sub-pixel makes the color gamut coverage up to 115% (NTSC CIE1976 standard);

6) The effective viewing angle is increased from 97° to 160° without losing brightness, and different angles are equally exciting;

7) Solid-state mechanism, no liquid substance, so the seismic performance is better, not afraid of falling.

8) The low temperature characteristics are good, and it can still be displayed normally at minus 40 degrees, while LCD can not do it.

9) The manufacturing process is simple and the cost is lower.

10) The luminous efficiency is higher, and the energy consumption is lower than that of LCD.

11) It can be manufactured on substrates of different materials, and can be made into flexible displays.

Disadvantage 1: The life span is usually only 5000 hours, which is lower than the life of LCD at least 10,000 hours;

2. It cannot realize the mass production of large-size screens, so it is only suitable for portable digital products;

3. There is the problem of insufficient color purity, and it is not easy to show bright and rich colors.

LCD TVs don't have this problem,And the screen is thinner than plasma TVs,Heat generation (plasma TVs usually use fans to assist heat dissipation) and power consumption are relatively low,It seems,It seems to be ahead of plasma TVs across the board,But it also has obvious disadvantages。 For example, the common low-cost LCD TVs on the market are generally not bright enough, and the screen brightness is not enough.

At present, the size of LCD TVs is generally smaller than that of plasma TVs,The size of the mainstream LCD TVs in the market is still below30Inch,Not only because the unit of LCD TV panels exceeds plasma TVs by about 30%,And only a few companies** can provide glass substrates suitable for manufacturing large-size LCD TV panels。

High LCD life. Low radiation; High clarity; Low power consumption; The response speed is slow, and the dynamic effect is worse than that of plasma

The difference between the quality of an LCD monitor should be distinguished from five aspects: backlight, screen, compatibility and life, which is also the five criteria for measuring the quality of an LCD monitorGreat standard

1. Backlight. The LCD screen itself does not emit light, and the light we see comes entirely from the backlight system behind the screen. Therefore, the application of new technology of backlight system in products is the first thing to pay attention to and consider, such as Sony developed and applied a new backlight system, this new backlight can increase the color range by 30%, and the color performance ability is excellent.

Because of technological innovation,Each manufacturer has invested the most in the research of the screen,There are many electronic components and new materials used,LCD TV has developed to the seventh generation of LCD panels to complete a leap in performance,The eighth generation of LCD panels has appeared,Even the ninth generation has been developed,Consumers can give priority to the selection of TV products with new panels when buying,If this is not too clear,You can check the relevant introduction on the relevant manual,If it is the latest product, there will be a detailed introduction。

3. Compatibility.

4. Lifespan. Second, the principle of LCD TV

Turn on the LCD TV to see the color of the TV and some adjustment functions, if the buttons are particularly flexible. And the color is also particularly full,Then such a TV is particularly good。

If you ask about quality, it is mainly related to the brand, and choosing some brands with a good reputation is the key If you are asking about performance, it mainly depends on the parameters, including resolution, contrast, power consumption, response time, etc.

In fact, the main difference is in terms of clarity,Because the picture sense of a bad LCD TV is still very poor。

There is no guarantee of TV shopping in China, and the quality is not as bad as online shopping

The LCD TV is very good, and I haven't found any shortcomings for the time being.
