Recently, Xiaomi released the supreme commemorative edition of Xiaomi TV master, with a price of 49999 yuan. Unlike most TVs, this TV uses Mini LED technology. What’s the difference? What is the improvement of display effect? Let’s learn about it through the article. < / P > < p > Mini LED technology is a new display technology. In addition to being used in TV, mini LED technology may also appear in tablet computers, mobile phones, watches and other intelligent devices in the future, so this new technology is worthy of attention. < / P > < p > Mini LED technology can be regarded as an upgrade of the traditional LCD screen, which can effectively improve the contrast and enhance the image performance. Unlike OLED self luminous screen, mini LED technology needs LED backlight as support to display pictures. < p > < p > the traditional LCD screen will be equipped with LED backlight, but the ordinary LCD screen backlight usually only supports unified adjustment, and cannot adjust the light and shade of a certain area separately. Even if a small number of LCD screens that support backlight partition adjustment, the number of backlight partitions has great limitations. < / P > < p > different from the traditional LCD screen backlight, mini LED technology can make the LED backlight beads very small, so that more backlight beads can be integrated on the same screen, thus dividing into more fine backlight partitions. This is also an important difference between Mini LED technology and traditional LCD screen. However, there is no clear official definition of mini LED technology at present. The data generally show that the size of backlight beads of mini LED display technology is about 50 μ m to 200 μ m, which is much smaller than traditional LED backlight beads. According to this standard, a TV can integrate a large number of backlight beads, which can easily create a lot of backlight zones. The more backlight zones are, the more fine the regional luminous adjustment can be achieved. < / P > < p > with the support of mini LED technology, the screen has multiple backlight partitions, which can control the brightness of a small area of the screen independently, so that the bright place is bright enough, and the dark place is dark, and the screen performance is less limited. When a certain part of the screen needs to display black, the small backlight can be dimmed or even turned off to obtain more pure black, which greatly improves the contrast, which is not achieved by ordinary LCD screen. With the support of mini LED technology, it can have the contrast close to the OLED screen. < / P > < p > the screen with mini LED technology also has the advantages of long service life and not easy to burn screen, and the cost will be lower than that of OLED screen after mass production. Of course, mini LED technology also has disadvantages, because more backlight beads are integrated, the thickness is not easy to be thin, and the concentration of multiple backlight beads is easy to generate more heat, which requires higher heat dissipation. < / P > < p > if you pay attention to products in the field of display, you will find that there are already many products using mini LED technology. In addition to the millet TV mentioned at the beginning of the article, Apple’s Pro display XDR monitor, laptop screen and other products have used this technology. < p > < p > last year, Apple launched the pro display XDR display. Although the official did not say that the mini LED technology was adopted, it was similar to the mini LED technology in terms of implementation principle. Apple Pro display XDR display adopts LCD panel, which is a planar backlight system. It has 576 local dimming partitions, which can independently adjust the light and shade of each partition, bringing an ultra-high contrast of 1000000:1. In addition to the ultra-high contrast, the display’s resolution, brightness, visual angle, and color performance are also top-notch. < / P > < p > more backlight partitions will cause heat dissipation problems. In order to achieve better cooling effect, the back of Apple Pro display XDR display is covered with dense cooling holes, which aims to improve the cooling effect as much as possible and reduce the impact of heating on the display. < / P > < p > from the official technical documents released by Apple’s Pro display XDR display, we can see that the reason why we chose Mini LED technology instead of OLED technology is that the screen has better consistency and continuous brightness performance, and it is not easy to burn the screen to bring long life. These are also the advantages of mini LED technology. < / P > < p > Mini LED technology can be seen as an upgrade on the basis of traditional LCD screen, which mainly solves the problem of contrast of traditional LCD screen, greatly improves the contrast and other aspects, and can bring better picture display effect. In addition to TVs and monitors that will use this new technology, according to information disclosed, the new iPad pro to be launched next year may also adopt Mini LED display technology, so this may soon become the mainstream display technology. < / P > < p > in addition to the mini LED technology mentioned above, there is also a micro LED screen technology with better effect. In short, micro LED screen and OLED screen are self luminous, which has the advantages of high contrast and high response speed of OLED screen. At the same time, because of the use of inorganic light-emitting materials, it is more durable, and there is no need to worry about burning the screen. < / P > < P > however, the micro LED screen technology is not yet fully mature LED technology is more mature and less difficult to implement, and the cost should also be reduced after mass production. For the time being, there may be more screens with mini LED technology. < / P > < p > Mini LED technology can greatly change the contrast of traditional LCD screen and bring excellent display effect. At the same time, there is no need to worry about burning the screen. Many manufacturers attach great importance to this technology, and more products with this technology should be launched in the future. Micro LED technology is more perfect and will become the mainstream when it matures. In the future, these two display technologies are worthy of attention. More Samsung devices can now run Android applications on PC through your phone
