Every industry has its own hidden rules, and the display is no exception. Some products seem to be high-end, but they have obvious weakness. Some products look at the discounts, but they also hide the mystery. For those who don’t understand the display industry, for a short time. It is difficult to figure out these doorways. As the price of the display becomes more and more favorable, people pay less and less attention to the display. They are not willing to spend too much thought on this kind of price-priced product. However, after the actual purchase, there are still some users who are smashing their chests and feel that they have not bought it. To the products that satisfy our content, today we will reveal the tricks of the display industry. The hidden secret behind the most popular 4K is the outbreak of 4K display this year. Various products are emerging one after another. Consumers are also very concerned about this new product. After all, the resolution of 4K is rising linearly compared with the resolution of 1080P. . This product has great potential for office and entertainment. The most exciting thing is that the price of 4K monitors is very favorable. Many people think that 4K monitors will cost 10,000 yuan, but many new products are priced at 3,000 yuan, which is only 1,000 yuan higher than the 25601440 resolution products. It can be said that it is very favorable, we must know that Apple's display does not reach 4K resolution. Rate, but still priced at around 7,000 yuan. For this reason, many users are beginning to flex their muscles, but they have not seen the true face of low-cost 4K monitors. They all use TN panels, and they have no wide viewing angle. It is difficult for users who are used to high-end displays to adapt to this old fashion. The panel, there is also a disadvantage that can not be mentioned is the 30Hz refresh rate, which also affects the use of 4K display. For the static picture, the 30Hz refresh rate can still cope with it. For the high-speed picture, the close-range viewing is serious, and the picture is not good. In the past, the contrast of the display has always been the technical point of the manufacturer's fuss. For example, LG's sharp ratio technology appeared in order to highlight the advantages of contrast, but today the dynamic contrast of the display has clearly become a digital game. For example, Samsung's display is basically 1 million: 1 dynamic contrast, and Acer's display has reached 100 million: 1 dynamic contrast, the difference between the two, the data comparison is already very obvious. But the two products put together, but did not see the obvious difference in contrast. In fact, the market also has a high refresh rate, wide viewing angle of 4K display, but the price of 10,000 yuan, the average user is difficult to accept, so this low-cost 4K display. The author is not criticizing this product. After all, it satisfies the desire of the entry user for 4K display, but in the process of publicity, consumers should be informed of the reasons for the offer, so that consumers can decide for themselves. Above we mentioned that the entry 4K LCD uses a 30Hz refresh rate, which reduces the cost. There is another type of display that increases the added value of the product by increasing the refresh rate, which is the gaming display. This product transitions from 60Hz to 120Hz, and now to 144Hz, the refresh rate is constantly improving, in order to better present high-speed images. We all know that there are a lot of high-speed images in the game, so 144Hz can make the picture more coherent. Then the implementation of 144Hz requires certain conditions, but many consumers do not know. First, to achieve a 144Hz refresh rate requires a better graphics card, old-fashioned graphics cards are difficult to support such a high refresh rate, which means that you buy a 144Hz refresh rate display, you need to transform your own hardware platform, which for many users In terms of it, it is unbearable. Although this is common sense, for those who don't understand the display market, I still occasionally make such mistakes and find that I have purchased a 144Hz product, but I can't use it. Secondly, the use process is more complicated, it requires a certain adjustment of the graphics card, and the same settings need to be made for the game. This process is simple and simple, and it is difficult and difficult to say. For different user groups, the operation is indeed It is a big difference. Finally, the 144Hz refresh rate is indeed achieved, but the graphics card and the display are not synchronized, it will still cause a certain smear, so nowadays there is a trend of synchronous optimization of the graphics card and display. In general, the 144Hz refresh rate product requires high hardware support, and the process of use is not very foolish, and it does not completely solve the problem of smear, so it can be said that it is not a perfect technology. LED backlight injury has no mention of LED backlighting, I have said many times, it has its own advantages, energy saving, small size, long life and other advantages, so that LED backlights are carried forward, not only in the field of display applications, In the field of LCD TVs, mobile phones and projectors, the existence of such a light source can be seen. The application is very common. It can be said that the current liquid crystal display devices are all LED backlight products, so there are also such statements as LED displays. In essence, it also refers to the LED backlight used in the display. LED backlights used in displays use LED display backlights, which are more compact and lighter. Today's LCD monitors can be made thin and light, and a large part of the credit goes to LED backlights. In the past, people used CCFL backlights. Not too short, but the power consumption is higher, and the volume is slightly larger, so the thickness of the display is difficult to reduce. However, although the benefits of LEDs are numerous, there are also fatal shortcomings, that is, LED backlights are easy to hurt, which is not known to many users. Long-term use of the monitor eye is easy to fatigue LED backlight is the use of blue LED plus yellow phosphor to achieve white light, so the white light in the white light component, medical research high-energy short-wave blue light damage to the eyes, so LED backlight The damage to the eyes cannot be ignored. Of course, this is not to say that the CCFL backlight does not hurt the eye at all. No matter what light source, the eyes are always staring at it, it will cause certain harm, but there is no doubt that the hidden danger of LED backlight is greater. In daily publicity, display manufacturers never mention the hidden danger of LED backlighting, which is a kind of concealment for consumers. Finally, the author also recommends long-term reading and learning, do not use LED light source, on the one hand there is blue light damage, on the one hand the color temperature is cold, it is not conducive to eye adjustment. 100 million: 1 dynamic contrast ratio has become the true contrast of the digital game LCD panel, in fact, at the time of delivery, it has basically formed. The contrast of LCD panels has indeed risen in these years, but there has not been a leaps and bounds in progress. From the very beginning, the liquid crystal display screen is not sharp enough. Until now, the contrast of the liquid crystal display screen is basically no problem, and the competition in contrast has come to an end. When consumers buy monitors, they don't have to worry about which product has a higher dynamic contrast ratio. The static contrast of the display is determined before leaving the factory: the disclosure of this article is not all the tricks of the display industry, nor is it a very bad secret. For example, LED backlight accelerates the development of the display industry to a certain extent, but it still has its own Disadvantages. These inferior manufacturers often do not selectively promote, so for users who are not familiar with the display industry, it is difficult to understand all the things, there will be some misunderstandings in the use, or spend money to buy a self Products that are not really needed, I hope this article can help some users to have a more comprehensive understanding of the display.
