What is Mini LED technology?
Mini LED technology is a new display technology. In addition to being used on TVs, Mini LED technology may also appear on smart devices such as tablets, mobile phones, and watches in the future. Therefore, this new technology is worthy of attention.
Mini LED technology can be regarded as an upgraded version of the traditional LCD screen, which can effectively improve the contrast and enhance the image performance. Unlike OLED self-luminous screens, Mini LED technology requires LED backlight as support to display images.
Traditional LCD screens will be equipped with LED backlights, but ordinary LCD screen backlights often only support unified adjustment, and cannot individually adjust the brightness of a certain area. Even if a small number of LCD screens support backlight partition adjustment, the number of backlight partitions has great limitations.
Unlike traditional LCD screen backlighting, Mini LED technology can make LED backlight beads very small, so that more backlight beads can be integrated on the same screen, thereby dividing it into more fine backlight zones. It is also an important difference between Mini LED technology and traditional LCD screens.
However, there is currently no clear official definition of Mini LED technology. The data generally show that the size of backlight beads of Mini LED display technology is about 50 microns to 200 microns, which is much smaller than traditional LED backlight beads. According to this standard, a TV can integrate a large number of backlight beads, and it can easily create a lot of backlight partitions. The more backlight partitions, the finer regional lighting adjustment can be achieved.
Advantages of Mini LED Technology
With the support of Mini LED technology, the screen has multiple backlight partitions, which can individually control the brightness of a small area of the screen, so that the bright place is bright enough and the dark place is dark, and the picture performance is less limited. When a certain part of the screen needs to be displayed in black, the small backlight subarea of this part can be dimmed, or even turned off, to obtain a purer black and greatly improve the contrast, which is impossible for ordinary LCD screens. With the support of Mini LED technology, it can have a contrast close to that of an OLED screen.
Screens using Mini LED technology also have the advantages of long life, not easy to burn, and the cost will be lower than OLED screens after mass production. Of course, Mini LED technology also has shortcomings, because it integrates more backlight beads, the thickness is not easy to be thin, and the accumulation of multiple backlight beads is also prone to generate more heat, which requires higher heat dissipation of the device.
Application of Mini LED Technology
If you are concerned about products in the display field, you will find that there are already many products that use similar Mini LED technology. In addition to the Xiaomi TV mentioned at the beginning of the article, there are also Apple’s Pro Display XDR monitors, laptop screens and other products. All use this technology.
Last year, Apple launched the Pro Display XDR display. Although the official did not say that it uses Mini LED technology, it is similar to Mini LED technology in terms of implementation principles. The Apple Pro Display XDR monitor uses an LCD panel, a flat backlight system, and has 576 local dimming zones, which can independently adjust the brightness of each zone, bringing a 1000000:1 ultra-high contrast ratio. In addition to ultra-high contrast, the resolution, brightness, viewing angle, and color performance of this display are also top-level.
More backlight partitions will cause heat dissipation problems. In order to create a better heat dissipation effect, there are dense heat dissipation holes on the back of the Apple Pro Display XDR display. The purpose is to maximize the heat dissipation effect and reduce the impact of heat on the display.
It can be seen from the official technical documents of Apple Pro Display XDR that the reason for choosing technologies like Mini LED instead of OLED is mainly because of the better consistency and continuous brightness performance of the screen, and the long life due to the difficulty of burning the screen. These are also the advantages of Mini LED technology.
Mini LED technology can be seen as an upgrade on the basis of traditional LCD screens. It mainly solves the problem of traditional LCD screen contrast. It has greatly improved the contrast ratio and can bring better screen display effects. In addition to TVs and monitors will use this new technology, according to the news, the new iPad Pro launched next year may also use Mini LED display technology, so this may soon become the mainstream display technology.
In addition to the Mini LED technology mentioned above, there is also a Micro LED screen technology with better results. Simply put, Micro LED screens are self-luminous like OLED screens. They have the advantages of OLED screens with extremely high contrast and high response speed. At the same time, because of the use of inorganic luminescent materials, they are more durable, so there is no need to worry about burning screens.
However, the current Micro LED screen technology is not yet fully mature, and the Mini LED technology is more mature and less difficult to implement. The cost should also be reduced after mass production. For the time being, there may be more screens using Mini LED technology.
summary
Mini LED technology can greatly change the contrast of traditional LCD screens and bring excellent display effects without worrying about burn-in. Many manufacturers attach great importance to this technology, and there should be more equipped with this technology in the future. Product launch. The Micro LED technology is more perfect, and I believe it will become the mainstream when it matures. In the future, these two display technologies are worthy of attention.
