To answer this question, we must first understand what is the difference between OLED and Mini-LED, and what is the difference between the two. Let’s get to know it with Brother T! First of all, what is Mini-LED technology? It can be roughly seen from the name that it uses very small LEDs to generate the light of the display. The official name of Mini LED is “sub-millimeter light emitting diode”, and the chip size is between 50~200μm (the diameter of a hair strand is About 50 microns), compared with the traditional LED, the size of Mini LED is only 1/40 of the original size! The roots of this new technology can be traced back to the traditional backlight LCD technology. Compared with the use of a single large or multiple smaller partial backlights, Mini-LED uses thousands of tiny LED backlights to provide extremely superior Local dimming characteristics. After the size is reduced, the panel of the same size can be equipped with more LED chips! The number of internally packaged LEDs reaches tens of thousands, and tens of thousands of μm-level Mini LEDs are arranged on the backplane and divided into thousands of areas. Although OLED also has the word LED, it has nothing to do with LED. OLED is the abbreviation of Organic Light-Emitting Diode (Organic Light-Emitting Diode). We will not go into the specific technical details. Simply understand it is an advanced flat panel display. Technology, with self-luminous characteristics, uses very thin organic material coatings and glass substrates. When there is an electric current, these organic materials will emit red, green and blue light to display various pictures and texts. At the same time, its color is generally regarded as superior to LCD TVs due to its self-luminous characteristics. Compared with traditional screens, OLED has advantages over ordinary screens in terms of color display and viewing angle due to the natural advantages of organic self-luminescence. However, OLED technology still has two major flaws that have not been resolved: lifetime and image retention. In contrast, the Mini LED screen can also achieve higher brightness, resolution, contrast… and the screen will be lighter and thinner than ordinary screens, energy-saving, and have a longer lifespan. The advantages of LCD and OLED can be taken into account at the same time. This is the advantage of Mini LED. It can greatly improve the contrast, brightness and thickness of the display panel. It is the peak image quality technology under the evolution of display technology and the best choice for improving the performance of LCD panels. Before the Mini LED is shining, TCL has insight into its “golden attributes”! As the company with the “earliest layout and first mass production” of Mini LEDs, TCL currently has X12, X10, C12, as well as TCL 8 series, TCL 6 series and other Mini LED smart screen products for overseas markets, covering from high-end flagships to affordable prices. The multi-price product line has formed a rich and powerful TCL Mini LED product matrix. If you want to feel the charm of Mini LED more intuitively, it is better to experience the TCL C12 quantum dot Mini LED smart screen can achieve 1000nit peak brightness and 10 million:1 ultra-high contrast ratio, making the bright field of the picture brighter and the dark field darker. , Bring more detailed performance.

First, as an organic light-emitting material, OLED is uncontrollable for the aging of each pixel. In addition, large screens are more sensitive to oled aging, and generally have a longer service life than iPhone, iPad and Mac, and are more likely to cause screen aging problems in user groups. Apple naturally does not want to take this risk. Secondly, the industry-recognized future development direction of the screen is micro-LED. Simply put, it combines the advantages of the current LCD and OLED. It can control the light emission of pixels individually, and can also avoid the aging of organic materials. It can greatly make the screen thinner and lighter, and the power consumption is reduced. The current mini-LED is a transitional form between the two, similar to the partition backlight on high-end TVs. The smaller the partition, the better the effect. Finally, the more important consideration is the commercial level. Samsung was the first to deploy and bet on the oled industry. The early products of the S series had various burn-in and color cast problems. However, it has been in business for many years and is currently almost invincible in the industry. If Apple chooses OLED as the future screen, it lacks technical barriers and is likely to lose the initiative and be subject to manufacturers. Therefore, Apple chose to create another track and jointly develop mini-LED and micro-LED together with manufacturers. Here everyone has a similar starting line, so that Apple has the technology in its hands in the future, so it will naturally have more voice and better control costs.

It’s very simple! The Oled screen will burn! For example, iPhone X with oled screen has burned screen in many cases. This has caused people who plan to buy second-hand iPhone full-screen mobile phones to worry about the burning of their mobile phones. Although the current technology has greatly extended the life of the OLED screen, the OLED screen uses a luminescent material, which has a half-life. The burn-in phenomenon will happen sooner or later. Mini LED has an oled display screen with high precision and brightness. Because it uses independent unit lamp beads smaller than the needle tip, it saves more power and does not burn screen. Some people say that Mini LED is an evolved version of LCD screens. However, it is not the ultimate version. More advanced than mini LED is Micro LED technology. However, the cost of the latter is relatively high, and it is still in the laboratory stage for the time being. Researchers have been thinking of ways to reduce its cost and finally mass production.

Mainly because of burn-in, organic matter is sometimes completely out of control, and some problems will occur inexplicably, while inorganic matter will be relatively stable. It should be considered here that the content presented on the large screen is very different from that on the small screen. The small screen (mobile phone) is limited by the screen area and basically presents very limited static content. A large amount of text and other processing needs to be transferred to the large screen. It is static for a long time, and the damage to OLED is obvious. Another reason is that Xiangzhuang Wujian intends to use Peigong. Originally, miniled is also an intermediate transition state. The entire panel has more than 10,000 LED light groups, and microled can achieve single-pixel self-luminescence with OLED, that is, one pixel. Corresponding to a microled, taking 1920*1080 as an example, about 200w microled lights are needed. This is basically a fantasy for the current process and yield, but vigorously promoting miniled can not only further reduce the cost and yield of miniled, but actually Shanghai also stepped on the accelerator for the mass production of microleds, which is why Apple chose minileds.

1. I don’t agree with the view that OLEDs are easy to burn screens. Apple’s size will never allow excessive repair rates, such as classic butterfly keyboards, not to mention more expensive screens. Refurbishing screens is a nightmare for Apple, but OLED has been used since the iPhone X. 2. I don’t agree with the view that Mini-LED is better. At least for now, Mini-LED and OLED still have their own advantages. OLED is lighter, thinner and more power-efficient, and can achieve pixel-level adjustment. Mini-LED has more advantages in brightness and is more suitable for large-screen devices. 3. I don’t agree with the view that OLED is more expensive. Mini-LED is a supply chain made by Apple forcibly. Compared with OLED, the cost of Mini-LED is astronomical. I have been thinking about this problem for a long time recently, and I feel that the following three points are more reliable. 1. Implement XDR display. Mini-LED may be the only option. Although technically speaking, XDR is not a separate standard for HDR, XDR is what Apple wants to see. HDR looks like. The following is Apple’s definition of XDR display brightness, which can maintain a peak brightness of 1000 nits, and a contrast ratio of 1600 nits is 1,000,000: 1 Judging from the above definition, in addition to contrast, top OLEDs are currently unable to do so. Take Samsung S21 Ultal, the king of OLEDs, for example, the brightness is around 900 nits, and the peak brightness is around 1300 nits, which is not up to Apple’s XDR standard. It is well known that large-screen OLEDs are more difficult to handle than small screens. If the iPad Pro’s 12.9-inch screen uses OLED, the technology still needs improvement. 2. Mini-LED can become Apple’s moat The key technology of OLED is in Samsung’s hands, and Apple needs its own moat. Therefore, Apple once again proved its status as the king of the supply chain with Mini-LED, and quickly matured the Mini-LED industry chain through its banknote capabilities. Just like the early Touch ID, it is difficult for other manufacturers to catch up in a short period of time. Samsung is dominating the OLED market, and Apple will never allow this to happen. 3. Mini-LED can make XDR the next Apple standard. Apple has laid out the P3 color gamut early on, and unified the color management of Apple’s ecology. Is accurate. This is very important for a profession such as a designer, and it is also the reason why every designer has a mac. Then the next standard to be unified must be XDR display. New addition: Apple will bet that the future Micro-LED technology will be updated~ Will Apple use all Mini-LEDs in the future? I don’t think it will. OLED is still very advantageous on mobile phones. It is lighter, thinner and more power-saving, and it can achieve pixel-level backlight adjustment. So I think Apple will use OLED on small screens and Mini-LED on large screens for some time to come.

I think some of the answerers actually didn’t get the point. Some people say that OLED display is poor, burn-in, etc., but there are not flat products without OLED on the market, such as Samsung’s Tab S7, and many domestic learning tablets use large-size OLED screens. Wouldn’t Samsung worry about these problems with OLED? But in fact, these problems are not obvious on the tablet. OLED has developed to this day, and its life span has been considerable, not to mention that tablet computers have a much shorter screen-on time compared to mobile phones. The problem Gao Zan said is completely non-existent, because the OLED screens currently used on Samsung Tab S6 and S7 series tablets are not arranged in diamonds at all. This arrangement does not share pixels, and the number of pixels is the same as the standard rgb arrangement. Stroboscopic is not a problem. Large-sized OLEDs can also be easily adjusted with DC or high-frequency PWM. For example, OLED TVs have DC dimming or 960Hz Pwm dimming. I think this is not a big problem. Not to mention that OLED itself has the characteristics of light and thin, low power consumption, and ultra-high contrast. It is simply too suitable for mobile devices. The really difficult problem is that under low cost, it is difficult for large-size OLEDs to achieve true HDR. HDR consists of two parts. The first part is high brightness, preferably with a peak brightness above 1000nit, and the second part is a partitioned backlight, preferably a pixel-level partitioned backlight. The brightness of large-size OLEDs is not easy to increase. This is related to its light-emitting principle. Organic self-luminous panels can only start with basic materials if they want to increase the brightness. If OLED is forced to increase the brightness, it will be easier to burn the screen. Tab S7 can only achieve 500nit brightness in the case of 11-inch LCD, while the 12-inch S7+ only has 420nit brightness, and he dare not even mark the brightness. LCD wants to increase the brightness, as long as the brightness of the backlight can be achieved, this can step into the threshold of true HDR. Although the partition backlight of OLED will be much easier, the brightness is not high, and there is still a quality gap compared with true HDR. . In the short term, this problem of large-size OLEDs is still not easy to solve. Whether it is Samsung or LG, at this stage, if you want to provide HDR 800 or higher on large-size displays, Mini-LED may be the only solution now.

Recently I went to the store and took a look at Samsung’s latest miniled screen TV on the spot, and talked about my opinion.
In the store, Samsung miniled TVs and LG and Sony oled TVs are all hung on one wall, and they play the same content, so the contrast is very obvious.
1. Samsung miniled TV is significantly brighter than LG and Sony oled TV. It is not a little brighter, but too much brighter (the display machine is generally adjusted to the maximum brightness). According to the staff, the peak brightness can reach 1500nit.
In terms of display black, oled is better than miniled when you look closely, but the gap is not big.
2. The power consumption of miniled TV is much lower than that of OLED TV. According to the staff, the brightness of the same size is only one third of OLED TV. The electricity bill comes next. The key is heat. Touching the miniled screen of the display machine by hand is a little bit warm, and if you touch the OLED screen, it is already severely hot, and the contrast is obvious.
3. Because the principle is different, the miniled screen does not have the burn-in problem of oled. This is too friendly to the need to display fixed content in a fixed area on the screen for a long time.
4. According to reports, the cost is lower. I haven’t studied this supply chain in depth, but from the price point of view, the price of miniled TV is cheaper than OLED.

In other words, although OLED is now the mainstream of the screen market, its own problems are very serious. Life issues. Because OLED uses organic materials, it will lead to short life of OLED screens. When OLED first appeared, there was a serious burn-in problem. Screen burn: Refers to the different aging degrees of the red, green, and blue lights. For example, blue is easier to aging, resulting in insufficient brightness. Therefore, only green and red glow, resulting in permanent yellowish screen. Even if the so-called diamond arrangement and Zhou Dongyu arrangement appeared to solve the problem of screen burn-in, it only increased the normal time of the screen. After 2 years of use, there will still be different degrees of screen burn-in problems. The price is expensive, and the current manufacturing threshold and cost of OLED panels are very high. For example, the current OLED notebooks are more than 2,000 more expensive than LCDs with the same configuration. In addition, it is not easy to grow bigger, but also because of technical problems, so it’s okay on a small screen like a mobile phone, but it’s not easy to make it on a laptop, and it’s even more difficult to make a TV. Therefore, since OLED has the problem of burning screen and the problem of high technical threshold, even if the technology is mature in the future and the cost is reduced, the life problem is still unavoidable. Instead of wasting time on OLED, it is better to use Micro/Mini LED to realize mass production as soon as possible. Mini/Micro LED is made of inorganic materials. First of all, it solves the problem of screen life. In addition, it also has low power consumption, high brightness, fast response speed, large viewing angle, light and thin, simple structure, almost no light consumption, etc. Features. Let’s put it this way, Mini/Micro LED consumes only 10% of the power of LCD and 50% of OLED, but the brightness is 3 times higher than that of OLED. Mini/Micro LED is actually the miniaturization of LED. The difference between Mini and Micro is only the size of the pixel pitch. Basically, the pixel pitch can become Mini at 100-300 microns, and Micro can even reach tens of microns. But the most important issue of Micro/Mini LED is mass production. As LED pixel particles have dropped to the micron level, realizing their mass transfer and ensuring high productivity and high yield has become a very important topic. This is an extremely delicate task, which places very high requirements on the technical level of various manufacturers. This is an important reason why Micro LED is difficult to produce. Take Apple, for example. He bought LuxVue, a company specializing in MicroLED technology, as early as 2014, but has not launched MicroLED products for a long time. This shows the difficulty of technology. This time Apple finally came up with Mini LED, which will inevitably bring a new trend in the screen market, wait and see!

The cost of large-screen OLED is high! In fact, Samsung’s own S7+ tablet uses AMOLED, and the display effect is indeed very good. As a kind of organic light-emitting material, OLED is most criticized for burning screen. But I have to remind, it’s 2021 now! OLED technology is quite mature, basically the kind of mature. The so-called burn-in phenomenon has long been ignored. There are not many electronic products that allow you to use burn-in during the life cycle! The main advantage of OLED is that the display is more brilliant and the brightness is higher, and because it is a self-luminous material, it can be made very thin and even bendable. So you will find that mainstream thin and light mobile phones and mobile phones with curved screens use OLEDs. Folding screen phones like Huawei, Xiaomi, Samsung, and Apple in the future must also be OLED. Unless Micro LED is commercially available in advance. But inferior OLEDs will indeed blind your eyes! So you still need to spend more money to buy OLED equipment. In the final analysis, Mini LED can’t get rid of the constraints of LCD, that is, the screen itself still can’t emit light, and it needs to rely on the light source on the back of the screen to illuminate the display. The optimization of Mini LED is mainly to replace the large LED behind the traditional LCD with countless smaller LEDs, the size of which is on the order of 100 microns. For example, Apple’s recently released 12.9-inch version of the iPad Pro 2021 has more than 10,000 Mini LEDs behind the screen. In this way, LEDs with a smaller volume or thickness can be used, and the screen can be made thinner. But if you are careful, you will find that the thickness of the previous generation of 12.9-inch iPad Pro 2021 is 5.9 mm, while the new one is 6.4 mm, there is still a price! These small LEDs can also be controlled separately in different areas. Then, when the black is displayed, a part of the LED can be completely turned off, and the brightness of a certain part of the LED can be increased when the display is highlighted. As a result, the contrast of the screen increases, and the contrast is always An important criterion for measuring the quality of a screen. And Apple actually managed to achieve 1000 nits of this LCD screen globally, which is really unacceptable! I am convinced of the 600 yuan increase. In terms of key technologies, Apple cannot be controlled by others. For example, the iPhone uses its own A-series chips instead of SoCs from Qualcomm, MediaTek, Samsung, or Huawei. For another example, on Apple computers, Apple is also replacing Intel’s chips with M-series chips. The screen has always been the core of digital products, but Apple has not many layouts. Although Mini LED is not enough to overthrow the status of OLED, but at least it can also form a dominant position. It’s not surprising that Apple pushed it hard! Maybe someday, the screen of Apple’s mobile phone will also be self-developed.

First of all, for products at this price, cost is not the first factor. OLED has not been used because of some inherent defects of its own technology, such as life problems, prone to burn-in, and yield problems. After so many years, they have not been well received. solve. Mini LED is essentially LCD-based display technology, but the actual effect is very close to OLED, plus the advantages of high brightness, more power saving, and high reliability. Apple also considered comprehensive considerations, and did not choose OLED, flat panel, and display. Generally, the service life is 5-10 years.

It’s certainly not because of the burning screen, Apple should be laying out the future! It’s all ages. OLED was only used by Samsung’s own mobile phones at the earliest. At that time, it was really burnt. At that time, I used Neuxs 2, the second son of Google, which Samsung produced for Google. That was the first time I saw an OLED screen. The black did not emit light. There is no light leakage problem. It is really cool to look at the black wallpaper or background. After a long time, I am fortunate that there is no burning problem. Looking at it now, it goes without saying that each flagship machine has a monochromatic OLED screen, and even thousands of yuan machines have begun to pile up Samsung OLED screens. If the screen burn is still a particularly serious problem, you should not see all OLED screen mobile phones now. Besides, the frequency of replacement of mobile phones is too high, and iPad and Mac products will take at least four or five years. After a long time, the stalk of the OLED screen burns up easily, after all, optimization is also a flaw! However, current large-screen devices rarely use OLED screens except for Samsung’s own products. Almost all the products used are expensive, so the price must be one of the factors that affects the iPad Pro. The iPad Pro is not cheap and has no shipments. The mobile phone is big, this kind of cost increase totally limited by Samsung is totally meaningless! Since you want to spend money, do something meaningful! Apple’s goal should be to get closer to the perfect form of Micro-LED, but limited by technology, it can’t be done now. It’s better to build a mini-LED as a transition. On the one hand, it can accumulate experience for the following Micro-LED, and on the other hand, the mini -LED can also be used as a current selling point. Obviously it is easy to see. When a new product is released, Apple itself does not even need to advertise. Various media outlets rush to report. Anyway, they spend money and do mini-LEDs by themselves, which can accumulate experience. , Don’t have to be limited to Samsung, it’s much better than giving all the money to Samsung’s custom screens, you can kill two birds with one stone!
