How to choose LCD TV

The method of choosing LCD TV is as follows.

1, choose a brand, the old brand is better than the current internet brand, which needs careful consideration.

2, the choice of size needs to be determined according to the location of each family's TV series.

3. Scientific content and resolution are important indicators of the whole TV series. Consumers pay more attention to after-sales service when choosing after-sales service.

How to choose LCD TV

Tips for choosing TV sets:

1, size

Many friends are keen on large-size TV sets when they buy them. In fact, the bigger the TV screen, the better. Does it matter to you? Room? The size of the screen is related to the distance between human eyes and the screen, which we call the viewing distance. According to the summary of many excellent posts on the Internet, there is a proportional relationship between screen size and viewing distance.

2. Grille

Turn on the power, turn the channel to the empty channel, then turn the contrast to the minimum and the brightness to the moderate to see if the scanning line is clear. It shouldn't be black and white, but there should be bright snowflakes.

In addition, after the power is turned on, the grating should appear within 14-20 seconds for ordinary tubes, and within 4-5 seconds for quick-opening tubes, and the brightness should reach normal. Otherwise, the picture tube has quality problems.

3. Processing chip

The image performance of LCD TV depends not only on the screen, but also on the internal integrated circuits, namely video and audio processing chips. The processing of high-definition signals can best test the strength of manufacturers, so the chips of well-known brands can give us more confidence.

Step 4 live in harmony

Finally, don't ignore compatibility issues. At present, the function of LCD TV is not only to watch TV programs and movies, but also to serve as the display terminal of computers, digital cameras, digital video cameras and other digital devices, so rich interfaces are very important.

5. Backlighting

The LCD screen itself does not emit light, and the light we see comes from the backlight system behind the screen. As we all know, color is not the strong point of LCD TV, so the new technology of backlight system is worth paying attention to when purchasing.

Liquid crystal TV (LCD for short) adopts a substance between solid and liquid, an organic compound with regular molecular arrangement, which is heated to a transparent liquid state and cooled to a turbid solid state of crystal particles.

The molecular structure of liquid crystal used in liquid crystal display is similar to that of thin matchsticks, which is called nematic liquid crystal. The liquid crystal display made of this liquid crystal is also called LCD. In LCD TV, a voltage is applied to the liquid crystal between two pieces of glass, and the picture is reproduced through the changes of molecular arrangement and twists and turns. The screen creates a picture through the collision of electron groups, and forms a picture through the perspective reflection of external light.

How to choose LCD TV?

Nowadays, LCD TV has entered thousands of households, and it is favored by people because of its long life. When choosing TV, people always think that the bigger the TV, the better. Actually, it is not. First of all, consider the indoor area, small-sized TV is not suitable. Second, according to the viewing distance, the acceptable range of human sight is limited. Therefore, when choosing a TV size, we suggest you look at the strategy first, which is suitable for you. Not much to say, choose the size of LCD TV that I watch with you.

First, the LCD TV size selection

The most important thing in choosing TV size is to match the viewing distance, that is, the distance between human eyes and TV screen, and the relative distance corresponds to a reasonable size. The specific calculation method is as follows.

If the viewing distance is 1.7m and the TV size is 26 inches; If the viewing distance is 2 meters, the TV size is 32 inches; If the viewing distance is 2.5 meters, the TV size is 37 inches; If the viewing distance is 2.8 meters and the TV size is 40 inches; If the viewing distance is 3 meters, the TV size is 42 inches; If the viewing distance is 3.5 meters, the TV size is 46 inches; If the viewing distance is 4 meters, the TV size is 50 inches; If the viewing distance is 4.2 meters, the TV size is 52 inches.

Second, LCD TV brand selection

1, Sony

Sony's most distinctive feature is the movement technology, which has good TV definition. You can show outstanding picture effects without a good panel. It is not recommended to buy the X series below the mid-range, and the afterimage is serious.

2. sharp

Sharp is the developer of LCD technology, so the original LCD panel is very important. So far, few brands can surpass Sharp's panel technology. The definition of TV is above average, but the only fly in the ointment is the slow channel change.

3. Panasonic Corporation of Japan

Panasonic's best is plasma TV, but the power consumption is a bit high. 10 years of plasma TV, you can buy a 60-inch LED TV when the electricity bill adds up. Its LCD TV screen is too bright in color and its definition is above average.

4. Samsung Electronics

Buying Samsung TV is most afraid of quality problems, which may be because the screen explosion time of mobile phones has affected the brand effect in the past two years, and the definition of its LCD TV is above average.

Third, LCD TV shopping projects

1, after-sales service

For LCD TVs, many manufacturers only provide warranty services ranging from 1 to 3 years, and some manufacturers provide free on-site service and maintenance fee reduction during the warranty period. These small details should be asked before buying.

2. Select the appropriate display size.

As mentioned above, different distances are used to choose different sizes, and we should do what we can.

The greater the brightness, the better.

Television is used to watch movies, and the comfort of watching is the factor. If the screen is too bright, your eyes will get tired after watching it for a long time.

The above is

What configuration do I need to buy a TV set?

What configuration should I look at when buying a TV set? With the continuous progress and development of science and technology, we have now produced a very intelligent TV set with multiple functions. Because of its variety, many people don't know how to choose. Let's take a look at what configurations are needed to buy a TV set.

What configuration TV do you want to buy? 1

1, screen quality

People also pay attention to the quality of TV sets, and the high definition of LCD TV pictures is its advantage. But in some cases, when watching movies with LCD TV, it can be found that LCD TV may appear tailing phenomenon in high-speed dynamic pictures, but plasma TV has some advantages over LCD TV.

Step 2 be clear

The definition of TV sets is the most important issue that we need to pay attention to when buying TV sets, and it is also the issue that people are most concerned about.

The definition of TV is also the resolution of TV. The higher the resolution, the clearer the TV picture. Generally, the resolutions of LCD TVs are 800×600, 1280×768, 1366×768, but now the resolution of 4K TVs seems to be four times higher than that of LCD TVs, which is one of the current TV resolutions.

3. Response speed

Compared with plasma TV, the response speed of LCD TV can be regarded as a weakness of LCD TV. The reaction speed of plasma TV is faster than that of LCD TV. The faster the response speed, the less TV tailing. The tailing phenomenon of LCD TV screen is also caused by the slow response speed of LCD TV.

4, the picture color

The choice of TV color is also a key point we pay attention to when choosing TV sets. The choice of TV color is not to let people choose the color of TV appearance, but the color of TV picture. Now the TV closest to the natural color is better, so that the color of TV is more restored and more acceptable to people. If the true color of the object is restored, the user's viewing experience will be more realistic.

What configuration should I buy a TV set? 2

1, size-you can't ignore its size when buying a TV. The larger the size, the higher the price. When choosing the TV size, we should consider the viewing distance, that is, the distance from the human eye to the TV screen. For example, 2.5 meters is suitable for TVs of 50 inches and below, 2.5-3 meters is suitable for TVs of 55 inches, and 3-3.5 meters is suitable for TVs of 65 inches.

2. Brands-It is best to choose well-known TV brands in the market, such as Sony, Hisense, TCL, Samsung, Sharp, Huawei, Glory, Skyworth, Changhong and Konka. Among these brands, the quality of TV sets won't be much of a problem.

3, picture quality-picture quality is related to the feeling of watching TV, the picture quality is not good, watching TV for a long time will feel uncomfortable, you should check the picture quality in different scenes.

4. Resolution-Now better TVs have been equipped with a resolution of 4k, and ordinary TVs also have a resolution of about 2K. The higher the resolution, the clearer and more realistic the picture will be.

5. Response time-TV response time is also an indicator to measure the quality of a TV. The response time refers to the corresponding time of the signal. Generally, the smaller the value, the better, and 30 milliseconds is the minimum standard.

What configuration should I buy a TV set? three

1, image quality

Of course, the first place is the image quality. The most important thing to buy TV is definitely the performance of picture quality. But now many TV brands don't pay enough attention to the picture quality, or even avoid the weight, and focus on promoting some flashy things, such as how thin the fuselage is, and the content is twice that of competitors. It can be said that the cart before the horse.

Parameters related to image quality include color gamut, HDR, etc. Gamut is a range of colors that can be represented. The following horseshoe chromaticity diagram may be familiar to you.

Proposed by CIE International Commission on Illumination in 193 1. Horseshoe-shaped area is the color gamut range visible to the naked eye, and the color gamut range that each TV can display is represented by a triangular area composed of three RGB points. The larger the triangle area, the larger the color gamut range.

CIE 193 1 chromaticity diagram

A higher color gamut means that TV can display richer colors, and the picture is not only gorgeous but also more realistic. Although a wide color gamut does not directly represent a good picture quality, a TV with a good picture quality must have a higher color gamut coverage.

Let's take a look at the hot HDR in the past two years. HDR(high dynamic range) is the abbreviation of high dynamic range, which was first used in the field of photography, mainly used to present rich light and dark information in TV.

However, HDR is not a technology, but a general term for display effects. Before it appeared, some TV manufacturers had made great achievements in this respect in order to achieve HDR effect, such as Sharp TV's brilliant color technology.

Contrast between light and shade of HDR lifting painting

Partition backlight control can intelligently analyze images and classify the brightness of backlights in different partitions, so that the brightness of backlight in the dark part is reduced and the backlight in the bright part is brighter, further enhancing the contrast of the picture.

In addition, bright color technology also has a magic weapon-brightness signal detection technology. The unique algorithm will intelligently calculate which part of each element in the picture should be brighter and which part should be darker. Combined with backlight control technology, the bright part and the dark part are controlled separately, thus making the contrast between light and dark more prominent.

Although there are more and more HDR TVs now, most HDR TVs will only be effective when playing HDR sources. It is realized by backlight control and signal source analysis without the support of film source. Any format of video can present HDR effect, so this image quality technology is of course more practical significance.

2. Excellent quality

Sound quality is also very important for TV, but now TV is getting thinner and thinner, and the sound quality is even worse than that of early CRT TV. Although the content is getting richer and richer, the sound is weak, which greatly affects the overall viewing experience. In fact, the pursuit of slim design and good sound quality is not completely contradictory.

3. Hardware configuration

Because the smart TV is equipped with an operating system, the hardware configuration must keep up, just like when we buy a mobile phone, we must buy those with high configuration, so that it will be smooth and will not get stuck.

Judging the hardware configuration of a TV mainly depends on the parameters such as processor, memory and flash memory. The combination of 2GB memory+16GB flash memory is relatively common at present, which will last at least 3-4 years. Besides, it is stronger. For example, Sharp's 8K TV is not only equipped with 64-bit chips, but also uses 5GB memory and 64GB flash memory, which fully considers the needs of the 8K era.

4. Appearance technology

With the progress of science and technology, the technical level of TV has been obviously improved. The frame, base and other parts are basically made of metal. After anodizing, drilling and cutting, they are very high-grade, and even the back design is very elegant, so the value of TV is getting higher and higher, at the expense of using metal materials and wire drawing technology.

In addition, the design trend of full-screen is very popular now. Not only in the mobile phone industry, "full-screen" TV can also bring good results when watching TV because it reduces the bondage of borders.

These are the four aspects that should be paid attention to when buying TV, especially the picture quality, because it can directly reflect the technical strength of a TV. If you want to buy TV in the coming double 1 1, you must keep a rational understanding of all kinds of propaganda terms and don't go out of tune.
