| Hello~ I am your der (Deer) a house that loves digital, likes to talk about current affairs hot spots, and digs cost-effective things.
Recently, der found that some friends quarreled over the OLED screen of the mobile phone.
Some people say that the screen of Samsung mobile phones is definitely the best, it looks full of transparency, and it is not comparable to domestic screens; Some people say that domestic mobile phones have used domestic high-end screens, and they can break the wrist with Samsung screens in many aspects, and the cost performance is higher; Some people also say that domestic mobile phones also use Samsung screens, but they are not as good as the Samsung screens of Samsung and Apple mobile phones... There is a lot of debate between Samsung mobile phone screen and domestic mobile phone screen.
So today der will talk to you, why do they say that Samsung mobile phone screen is good, domestic mobile phone screen is always worse?
Three factors that determine the quality of a mobile phone screen
Many people always say that the Samsung mobile phone screen is good, and feel that it looks clearer than many domestic mobile phone screens, and the brightness is higher, so the clarity and brightness of the mobile phone screen has become a measure of the quality of the mobile phone screen by many small partners.
But the friends who have bought a monitor know that the quality of the screen is not only based on the clarity and brightness, but also depends on the luminous substrate, color gamut, color accuracy, color depth, screen uniformity, power consumption... In all aspects, so we have to know first: the standard for measuring the quality of mobile phone screens.
Generally speaking, the quality of mobile phone OLED screens is mainly determined by three important factors - light-emitting substrate, substrate and pixel arrangement.
As the core component of OLED screens, the light-emitting substrate largely determines the luminous efficiency and quality of the screen; Under the foundation of a good light-emitting material, a very thin glass substrate is required to attach to the above display; The pixel arrangement determines the pixel density, clarity and other aspects of the screen.
Taking the latest iPhone 14 Pro Max as an example, it uses Samsung's latest M12 material combination of diamond arrangement OLED screen, resolution of 2796&1290, pixel density 460PPI, Delta-E value of 0.26 (where 0 is perfect), support 120Hz adaptive refresh rate, peak brightness of 2000 nit. From these parameters, it is clear that the Samsung screen of this Apple phone is very good.
Samsung OLED screen of "hexagonal warrior"
In the field of today's OLED screen, Samsung exists like a ceiling, like Samsung mobile phones themselves are their own top M series material screens, except for the rich Apple, basically not for sale. Generally, it is the "castrated version" of the E-series material screen.
Other mobile phone manufacturers are hyping their Samsung E6 screen, how powerful and powerful, and Samsung mobile phones themselves use better M series material screens, but do not hype how good their screens are, after all, the screen used by Samsung mobile phones is already recognized as the "best OLED mobile phone screen".
The reason why Samsung can achieve a recognized good screen is inseparable from its monopoly on the technology of light-emitting materials and material supply.
For example, Samsung's top M series screen, behind the research and development of high-end chemical materials, with the support of the world's top chemical companies, the ratio of these materials is completely confidential.
Although we look at domestic mobile phones with E6 screens and feel that the look and feel is already very good, the top M13 screen provided by Samsung to the iPhone 14 Pro Max is the world's best raw material provided by top companies in the United States, Japan and South Korea, such as Dow Chemical, South Korea's DS Neolux, Merck and so on.
Among these luminescent substrates, red and green phosphorescent materials also have the monopoly of corresponding suppliers, and Samsung's SDI company is one of the monopoly giants. Of course, the rich and rival Samsung also controls more of these material monopoly giants through investment holding to maintain its solid position in the high-end OLED screen market.
In Samsung's handheld key light-emitting material research and development technology, including many upstream materials of the panel industry chain, plus its own "banknote ability", so that each key node in the OLED field is in an advantage, even if the color saturation of the Samsung mobile phone screen is full for you, it still does not affect the existence of its "hexagonal warrior".
So from raw materials to supply chain, the domestic screen is still a little worse than the Samsung screen after all, but in the face of the Samsung screen of the "hexagonal warrior", the domestic screen is not afraid.
Domestic screens taking off one after another
Due to the internal volume of the domestic mobile phone market, mobile phone manufacturers initially rushed to choose Samsung screens for their flagship mobile phones to ensure the best display effect and as a publicity gimmick.
From the "offcut" E2 material screen to the latest customized E6 material screen, domestic mobile phones can be said to have launched banknote capabilities from poor to good, and even specially "customized" Samsung screens.
No way, after all, before 2018, the quality of domestic screens is indeed not dropping, such as what "Zhou Dongyu" arrangement and other domestic OLED screen performance, the price is expensive, four or five thousand flagship machines are not as good as the screen display effect of some low-end mobile phones.
Since the technology can not keep up, then use time to make up, when domestic screens compete for technology research and development, Apple, a wealthy bully, does not want to be tied to Samsung with screens, and finds other mobile phone screen manufacturers everywhere to try, giving domestic screen manufacturers a chance.
Coupled with the expiration of the monopoly contract between Samsung and the major panel industry chains, and the expiration of the patent of the most core light-emitting material of OLED screens, domestic screen manufacturers can also get better material resources and better equipment for research and development.
So in a few years, domestic BOE, Tianma and Huaxing Optoelectronics and other screen manufacturers began to "take off", and rushed to launch a variety of high-level screens, some screens can take out their hands and Samsung screens to break wrists, and even affect the shipment of Samsung OLED screens in 2018.
Especially in the past two years, the development of domestic mobile phone screens has finally seen Samsung's "back".
Like the 2K screen of Redmi K60 some time ago, it is the latest Huaxing Optoelectronics C6 material screen, and some bigwigs compare it with Samsung E6 straight screen, and found that sRGB/P3 full coverage, the best mode average △E 0.9, medium and high brightness / low brightness uniformity and other aspects can be said to be comparable, but the gap in screen luminous materials makes this "handy" top screen still inferior to Samsung E6 screen in terms of viewing angle and high brightness.
No way, after all, Samsung is better in the research and development of light-emitting substrates, coupled with the top upstream technology and a more mature screen panel industry chain, if the domestic screen wants to really take off, it must make a breakthrough in the research and development of light-emitting substrates.
Nowadays, domestic mobile phones have begun to use domestic top screens, and the performance of domestic screens has also been recognized by users, making the share of domestic screens in the mobile phone market continue to increase.
But a reality to know is that as far as high-end mobile phone screens are concerned, domestic screens are still difficult to face Samsung in a short period of time, but domestic screens have taken off, taking advantage of the best development era, der believes that domestic screen manufacturers have made breakthroughs in display technology, and established their own perfect supply chain, and finally made breakthroughs in the research and development of luminous materials.
Finally, although the Samsung mobile phone screen is good, the domestic mobile phone screen is not bad.
