Additional knowledge: How to choose an LCD TV
In addition to the tricks introduced above when purchasing an LCD TV, there are other things to consider, such as interfaces, LCD panel size, resolution, etc. In short, as a consumer, you need to learn more professional knowledge, not be superstitious about the parameters in manufacturers' advertisements, focus on your own feelings from actual viewing, and shop around, so that you can buy a satisfactory LCD TV.
How to distinguish various types of LCD panels
For flat-panel TVs, the display screen is the most important component, accounting for about /3 of the cost of the whole machine. LCD screens are divided into ordinary screens, ordinary screens and professional screens due to different technologies and skills. This kind of display screen is a special screen for LCD TVs. It has greatly improved in image resolution, color, and texture. It can truly reproduce digital high-definition picture quality, and is especially suitable for receiving digital TV. LCD screens on the market today are divided into three grades: the best quality ones are Sharp screens, but they are not available at all, followed by screens from Japanese and Korean manufacturers, such as Samsung Electronics () and finally screens produced by Taiwanese manufacturers, such as AUO. and Chimei. Now only these five major manufacturers have the ability to cut large-scale LCD panels above an inch. Choosing a panel from a large manufacturer with advanced technology will have advantages for future use, such as longer service life and color than low-end panels. The following introduces the characteristics and differentiation methods of several common LCD panels.
, Check the picture tailing
The human eye has a certain reaction time when watching dynamic pictures. If the response time is long, the lag of the moving picture will appear, which will greatly affect the picture effect. If the response time is shorter, in When watching fast-moving pictures, you won't feel any afterimages or traces of drag. Picture tailing was a disadvantage of early LCD TVs, but with the continuous improvement of technology and technology, the response time of most LCD TVs has been shortened to milliseconds, and some even reached milliseconds. Such a short response time is now far shorter than Human eyes are quick, and the tailing phenomenon that was easily caused by fast-moving images in the past almost no longer exists. However, in addition to the response time, the optimization of the manufacturer's algorithm will also have a great impact on eliminating tailing and afterimage phenomena.
Nowadays, some LCD TVs have completely eliminated the tailing and afterimage phenomena through innovative technological improvements. For example, Konka Sports TV uses digital motion compensation circuit and dynamic 3 noise reduction technology. This technology can quickly check TV signals in an instant, adopt different methods for moving areas and stop areas, eliminate snow blur in moving pictures, prevent comb teeth in moving parts, ensure the proper sense of speed, and effectively eliminate tailing scene.
When we buy a TV, we need to look at the TV screen from multiple angles. For example, choose the angle to face the screen, then shift some angles, and stand on the same horizontal line as the TV screen to see if When inspecting the machine after seeing the pictures, you can also ask the promoter to play some faster pictures to see if the movements on the pictures are connected and whether there is tailing in the picture.
Easily identify dead pixels and bright spots
When some brothers were buying LCD TVs, they saw that the picture shown by the promoter was perfect, but after buying it for a while, the bright and dark pixels were broken. Dots appear on the screen one after another, which seriously affects the screen effect. It is not that simple to go to the merchant to discuss it. So how can we identify whether the LCD TV has dead pixels or bright spots when purchasing? There are three methods to choose from:
The simplest method is to make the screen completely black and watch in pure blackness. Are there any highlights? Then make the screen completely white and see if there are any black spots. Finally, switch to red, green, and blue to check the completeness of the color points. If during the inspection you find that there are more defective pixels than the national specification, don’t buy it.
Another method is to connect the computer to the LCD TV, and then display the required picture through a solid color picture in software such as . You can also select a desktop of the corresponding color in the computer desktop properties to view. This method is the same as the viewing method when purchasing an LCD monitor.
The third method is to use disc viewing, which is a home theater audio-visual test disc. The original version of this disc has Chinese subtitles, explaining the complicated test processes in detail. It enters the testing process when watching the disc. During the testing process, it can be seen at a glance whether the LCD TV has dead pixels or bright spots.
, Contrast is tricky
Contrast refers to the ratio of the brightness of the brightest pixels and the darkest pixels in the image displayed on the screen. It directly affects the transparency of the image, the brightness of the color and the clarity of the image. Spend. To put it simply, the higher the contrast, the whiter the white we see and the purer the black. But when you walk into a home appliance store, you will find that the marked contrast values are all kinds of, which makes people a little headache, such as effective contrast:, dynamic contrast:, maximum contrast, etc. If you think the higher the contrast, the better the product, then you are right. Manufacturer’s digital trap.
In fact, these numbers cannot reflect the contrast performance of flat-panel TVs. They are just numbers. The contrast effects of different brands, series, and types are indeed different, but their different sizes are the same. The numbers indicated are not directly related.
For the identification of TV contrast, when purchasing, you can ask the salesperson to put some discs with particularly dark scenes under normal lighting conditions, and adjust the contrast of the TV to the middle to see if the details of the picture can be clearly seen. For example, in the night scene, if you look at a black building, can you clearly see it? If the details cannot be distinguished, the contrast of this TV will not be very good in darkness. Then show some particularly bright pictures, such as surfing pictures under strong direct sunlight. The faces of athletes and the waves are clearly layered. If the details of the picture are lost and only white flowers are seen, then the contrast is not very good. Generally speaking, if the contrast is poor, the color will be severely mutated, losing its color and luster, and its texture and details will be unclear. In this regard, international brands may do better than small and medium-sized brands, high-priced LCDs do better than cheap ones, and small-sized screens are better than large screens.
. Prepare for a rainy day and keep an eye on the service commitment
LCD TV is a home appliance product with a relatively high technical content, which also means that once there is a quality problem, repairing it is also very troublesome. When purchasing an LCD TV, consumers must learn more about the details of the three-guarantee product from the seller or manufacturer, including: the three-guarantee period for the complete machine, the three-guarantee period for major components, a detailed list of major components, etc. Most manufacturers provide warranty services ranging from 3 years to 3 years. Some manufacturers even provide free door-to-door service and reduction of repair costs during the warranty period. These small details should be clarified before purchasing, and the operators should be aware of the three guarantees. The commitment is clearly marked in text on the three-guarantee voucher or invoice.
Among domestic machines nowadays, the ones worth buying are
Sony, R, R and B series.
Toshiba's 3., series.
Panasonic's 3 series.
of, series
The domestic brands with poor picture quality are LeTV and Xiaomi, which cannot be called TVs at all. The second worst ones are Konka and Skyworth, and in terms of quality, we are generally average (Hua, Hisense, Haier , Changhong, Panda, etc.). To put it bluntly, domestic brands now just buy a screen, casing, and driver board and assemble them. They are all competing for cost and sales, with little technology investment or research and development funds. Therefore, the picture quality of domestic TVs is naturally very good, and the after-sales service is also very good. Once there is a problem, you go to the after-sales service and they will evade it. I personally think that if you want to buy a TV that costs more than 1 yuan, there is no need to buy a domestic brand. .
The TV sets with the best quality and image quality today are the Japanese, American, and Western European versions that are sold to Europe, the United States, and for personal use. In Japan, Toshiba has the best sales and reputation for use, followed by Sony.
In the evaluation results of two of the most professional magazines/magazines recognized by the Japanese audio-visual enthusiast industry, Toshiba ranked first in picture quality, followed by Sony B. In the past three years, Toshiba ranked first in picture quality, followed by Sony B Sony and Sharp. The kings of image quality are Toshiba and Sony. .
The Hong Kong version and other Asia-Pacific versions are okay, but the mainland version is the worst. Circuit chips and panel levels have shrunk in various ways, and even secretly. However, Chinese people have always worshiped foreign countries and have low taste. They only care about appearance and function. He likes to be fooled, so few people can detect it.
When buying a TV, I recommend you to take a look at Japanese professional reviews. The so-called review organizations in the mainland have low qualifications and editors have no talent. Most of them receive money from the manufacturers. The so-called reviews are completely nonsense. Basically, it has no reference value. Therefore, Japanese original products and those sold in the mainland are completely different things. .
The picture quality of Samsung TVs has never been outstanding. What is good about Samsung is the panel. The original picture quality of the black crystal-panel of 2008 is very good, with high contrast and deep black. It is favored by high-end products from Sony and Toshiba. LCD was used, but the cost was high. After the panel factories that Sony and Samsung collaborated with separated, Samsung stopped producing black crystal in 2000. The so-called panels that followed were all cheap and shrunk, and the picture quality deteriorated greatly. . Last year's Samsung TV was exposed by a forum expert. Its TVs were divided into test versions and commercial versions. Once I accidentally sent the commercial version to an evaluation organization, and the blue level was detected. There is overflow, the green level is super low, the overall image quality is bluish, the contrast is weird, and the colors are too light. Later, Samsung gave some money through its public relations, saying that it had sent the wrong phone, and sent a new test version for review. It's very cheap, right? The picture quality of Samsung's series and series after the year has greatly declined. The scale of domestic panels has shrunk sharply, and waste produced in Suzhou is used as backlight. I saw the Samsung-funded TVs in B's "Love Come Home" and the Samsung TVs used in some current affairs programs on Southern TV. The picture was horribly bluish and the picture quality was disgusting. .
However, Samsung’s after-sales service is very good. As long as you find serious light leakage, dead pixels and scratches, they will replace it with a new one easily. .
Sharp is not a good product. Among Japanese manufacturers, it is the most qualified to shrink its products. It was the first to use Taiwanese panels, boasting four-color technology and Japanese original panels. But if you actually look at the picture quality, you will feel that everything is fart, the motion is blurred, the black level is smoky, and some series still have color cast problems. People His skin is the color of pig liver. Sharp's high-end panels are not even used by themselves. Most of them are used as monitors and have excellent functions. However, when they are decentralized for civilian use, only a few R models have good picture quality and can be considered qualified. And the so-called R, , 3 and so on later The mid-to-high-end models all have unqualified image quality, but the prices are still high. . Sharp was content with its own shrinkage, and also brought in several other good Japanese brands. Sony, Toshiba, and Panasonic later followed suit. . Now that Sharp's LCD factory has been sold to Foxconn, high-grade Kameyama panels have been discontinued in the early years. Now they are mass-producing cheap and shrink-cut panels, so costs can be controlled. Sharp's after-sales service is quite satisfactory, and its customer service is condescending.
Let me tell you, the LCD picture quality before 2000 was quite satisfactory. At that time, the oil painting feeling of my TV was particularly strong, so I didn’t like it. The so-called engine, in terms of dynamic definition, standard definition, and non-point-to-point picture quality, No major improvement has been seen, and the level of standard definition optimization technology is average. The color grading technology and image processing technology of Korean TVs have always been average and far inferior to Japan. Overall value for money is average. . Years later, Small World was launched. Since the beginning of the series, the picture quality has improved significantly, the price is reasonable, and the plan is conscientious. . But since the beginning of this year, the picture quality of the new B series has actually begun to shrink and become worse. The price is a little more expensive than the series, which is a bit of a trap. The forum experts discovered it. In terms of after-sales, there are many quality control problems with LCDs produced in Guangzhou. This is true for monitors and TVs. Its panels are recognized to have the most light leakage, dead pixels, and negative and yang issues. However, if you find something is wrong after delivery, you can raise a problem. If you want to replace it with a new one, you will at most have to deal with the after-sales service for a while. .
Panasonic Plasma, the so-called screen launched at the beginning of this year, is basically a low-cost and shrunk product. The power consumption is reduced, but the picture quality is also reduced. After replacing the original plasma phosphor with a cheap one and simplifying the image quality processing circuit, the screen started to flicker significantly and the brightness seemed to be a bit higher. It was said to increase the luminous power. However, the noise in the dark parts and the highlight image were compromised. People with sharp eyes found that , the colors of Panasonic's later models tend to be more like liquid crystal texture, and the transparency becomes worse. . These shrunken products from the beginning of the era to the end are just the same. . In addition, Panasonic had a large number of black line failures in the 3 era, which scared many people away. The plasma brand was completely finished, and it was not at all the high image quality level that Panasonic had in the past and years. .
