What is the difference between screens with miniled backlight technology? Xiaomi released the supreme commemorative version of Xiaomi TV master, which costs up to 49999 yuan. Unlike most TVs, this TV uses miniled technology. What’s the difference between this technology? How does the display effect improve? Let’s learn about it through the article.
What is miniled technology?
Miniled technology is a new display technology. In addition to being used on TV, miniled technology may also appear on smart devices such as tablet computers, mobile phones and watches in the future. Therefore, this new technology is still worthy of attention.
Miniled technology can be regarded as an upgraded version of the traditional LCD screen, which can effectively improve the contrast and enhance the image expressiveness. Unlike OLED self luminous screen, miniled technology requires LED backlight as support to display the picture.
The traditional LCD screen will be equipped with LED backlight, but the ordinary LCD screen backlight often only supports unified adjustment and cannot adjust the brightness of a certain area alone. Even if a small number of LCD screens support backlight partition adjustment, the number of backlight partitions has great limitations.
Different from the traditional LCD screen backlight, miniled technology can make the LED backlight beads very small, so that more backlight beads can be integrated on the same screen, so as to be divided into more fine backlight partitions, which is also an important difference between miniled technology and traditional LCD screens.
However, at present, there is no clear official definition of miniled technology. The data generally show that the size of the backlight bead of miniled display technology is about 50 microns to 200 microns, which is much smaller than the traditional LED backlight bead. According to this standard, a TV can integrate a large number of backlight beads, which can easily create a lot of backlight partitions. The more backlight partitions, the finer regional luminous adjustment can be realized.
Advantages of miniled Technology
With the support of miniled technology, the screen has multiple backlight partitions, which can independently control the brightness of a small area of the screen, so that the bright place is bright enough, the dark place is dark, and the limitation of picture performance is less. When a part of the screen needs to display black, the small backlight of this part can be dimmed or even turned off to obtain more pure black and greatly improve the contrast, which can not be realized by ordinary LCD screen. With the blessing of miniled technology, you can have a contrast close to the OLED screen.
The screen with miniled technology also has the advantages of long life and not easy to burn. After large-scale mass production, the cost will be lower than that of OLED screen. Of course, miniled technology also has disadvantages, because it integrates more backlight beads, the thickness is not easy to be thin, and the accumulation of multiple backlight beads is also easy to generate more heat, which has higher requirements for equipment heat dissipation.
Application of miniled Technology
If you pay attention to the products in the display field, you will find that there are many products using miniled technology. In addition to the Xiaomi TV mentioned at the beginning of the article, Apple’s prodisplayxdr display, laptop screen and other products use this technology.
Last year, Apple launched the prodisplayxdr display. Although the official did not say that it uses miniled technology, it is similar to miniled technology in terms of implementation principle. Apple prodisplayxdr display adopts LCD panel, which is a planar backlight system. It has 576 local dimming zones, which can independently adjust the light and shade of each zone, bringing 1000000:1 ultra-high contrast. In addition to ultra-high contrast, the resolution, brightness, visual angle and color performance of this display are also top-notch.
More backlight partitions will bring heat dissipation problems. In order to create better heat dissipation effect, dense heat dissipation openings are spread on the back of apple prodisplayxdr display, in order to improve the heat dissipation effect as much as possible and reduce the impact of heat on the display.
It can be seen from the technical documents officially released by Apple’s prodisplayxdr display that the reason for choosing technologies such as miniled rather than OLED is mainly because of the better consistency and continuous brightness performance of the screen, as well as the long life brought by the difficulty in burning the screen. These are also the advantages of miniled technology.
Miniled technology can be regarded 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 can bring better picture display effect. In addition to the new technology used in TVs and monitors, it is revealed that the new iPad Pro launched next year may also use miniled display technology, so it may soon become the mainstream display technology.
In addition to the miniled technology mentioned above, there is a microled screen technology with better effect. In short, microled screens, like OLED screens, are self luminous. They have the advantages of high contrast and high response speed of OLED screens. At the same time, they are more durable because they use inorganic luminescent materials, so there is no need to worry about burning the screen,
However, at present, microled screen technology is not yet fully mature. Miniled technology is more mature and less difficult to realize. After large-scale mass production, the cost should also be reduced. For the time being, there may be more screens with miniled technology.
Miniled 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 screen burning. Many manufacturers attach great importance to this technology, and more products equipped with this technology should be launched next. The microled technology is more perfect, and I believe it will become the mainstream when it matures. In the future, these two display technologies deserve attention.
