If you pay attention to the smartphone market in the recent period, you may have noticed that many ** smartphones in the near future, especially new high-end models, have generally begun to promote the "hard quality of the screen" as an important selling point.
In this context,Almost every high-end model will be mentioned at the press conference,They use the latest panel of a certain screen factory,In terms of resolution、Color、Color accuracy、Latency、Brightness and other indicators,Compared with the past, there has been great progress。
Among them, the most eye-catching is the indicator of "brightness". Because in the past two or three years, it is still difficult to find a few models with a nominal peak brightness of more than 1500nit in the entire market, in fact, until the middle of this year, mobile phone screens that can reach a peak brightness of more than 2000nit are still rare.
But just in the last few weeks, there has been a large number of new phones claiming that they use 4000nit, or even more than 4500nit peak brightness screens. Even according to relevant revelations, in the first half of next year, some manufacturers may launch mobile phone screen solutions with a peak brightness of more than 6000nit, trying to seize this "brightness index" to a new high.
Then the question arises, why does the screen of a smartphone become so bright all of a sudden, and is it really necessary for consumers?
Why does the mobile phone screen suddenly "light up", because there is a new demand
First of all, let's explain why the brightness of the smartphone screen suddenly increases.
The underlying reason for the increase in brightness,Of course, the material of the screen itself has improved,This can actually be explained in one sentence。 That's the new screen paint formula, which now excites more light at the same or lower energy consumption, which is the most direct factor in the "brightening" of the mobile phone screen.
Of course, where there is demand, there is supply. The improvement of the chemical composition of the screen material is a supply-side factor, so there must be a related demand stimulus. Otherwise, there is no way to explain why several different screen factories will "invariably" achieve material replacement this year. After all, if it's just a simple formula iteration, why didn't there be much progress in the first two years, but this year, it will collectively "brighten up"?
To find the answer to this question, we need to look at the end product. When you look at the smartphones that have just been released this year and have significantly brighter screens, it is not difficult to find that they all have in common the generally enhanced HDR** shooting and playback capabilities, and the general support for HDR** shooting functions.
Specifically, for example, the realme GT5 Pro and OnePlus 12 both support the Dolby Vision** shooting capability that their respective brand models did not have in the past.
At the same time, these two models, along with the Vivo X100 series, also support HDR** shooting based on brightness metadata (although each company has a different name for this feature, it is bound to be connected to the unified standard of Android in the future).
In addition, in terms of ** playback, Redmi's first 4000nit peak brightness screenK70 Pro has also become the brand's first model adapted to "cinema mode" and specifically enhanced HDR*** effect.
The birth of the HDR standard has given the high-brightness screen a basis for its existence
Seeing this, some friends may say,Doesn't the previous mobile phone screen support HDR、Can't play back HDR**and**,Why do you pursue HDR must be these ultra-high brightness screens now?
The reason is actually very simple, it is true that the screen in the past was still too dark.
First of all, we need to understand why the entire industry is now emphasizing HDRIn fact, this is because there are big problems with the SDR (Standard Dynamic Range) film and television standards that have been implemented for many years. To put it simply, in order to accommodate the inferior hardware indicators of display equipment at that time, the SDR standard artificially imposed excessive and "one-size-fits-all" restrictions on the color range and brightness range involved in the entire shooting, editing, and playback process.
It is precisely because of the restrictions that in the past, even if the screen size of TV and movies in the past was large, the human eye would still instinctively feel "very unreal". Because the color and brightness information on the screen is too different from the amount of information we usually see in nature. In other words, compared with the color and brightness of nature, the quality of SDR movies and SDR displays in the past is really "weak".
From this point of view, HDR is not actually like an "enhancement" of the old display standard, but more like a "correction" and a "emancipation of the mind". The HDR standard encourages display devices to use the highest possible color and brightness to reproduce the natural light and object color as much as possible, because only in this way can the audience fundamentally feel that the scene on the screen is more realistic and more "immersive".
But the problem is that the brightness of nature is very, very, very high. So this has led to the fact that in the years since the birth of the HDR standard, although we know how bright the picture "should" be, there have not been too many display devices that have actually been able to achieve this brightness.
For example, Dolby Vision, as the most recognized and effective HDR standard, requires 12-bit color depth for the film and up to 10,000nit for peak brightness. But for a long time, even the screen of flagship smartphones has only stayed at the level of 10-bit color and more than 1000nit, and the color is more than 60 times worse than the requirements of Dolby Vision, and the brightness is less than one-fifth. On such a screen, it is obviously impossible to expect its ** playback to be good.
Because of this, the significance of these ultra-high brightness screens this year is even more real. If nothing else, at least they do get closer to the "ideal" when shooting and playing back the top HDR** and **, and are destined to be significantly better than the previous low-brightness devices.
Should consumers go after new screens?Yes, it's actually good for everyone
Some friends may say,I don't have a membership of the major ** platforms,So I don't have any concept of high-quality HDR**,Is it still meaningful to have an ultra-high brightness mobile phone screen in this case?
Of course there are. On the one hand, in order to reflect the experience improvement brought by the "new screen", major manufacturers must make some efforts to explore related functions. For example, as mentioned earlier, many of these models will turn on the camera's HDR mode by default, and the ** shooting will have built-in light information, and the HDR mode of the screen will be activated when it is on its own screen**, which will look significantly more tolerant than the ordinary**, with higher contrast, and a more sense of presence.
On the other hand, don't think that a "brighter screen" is necessarily brighter in any situation. In fact, this is not the case, because when the mobile phone uses the vast majority of everyday apps, it actually still has to follow the traditional color and brightness industry standards. That is to say, at this time, these models equipped with new screens do not necessarily look brighter than the previous models, but because their screen luminous efficiency is objectively improved, so when in a lower brightness mode, the advantages of the new screen in energy saving can be more reflected.
When the market is dominated by hardware, it's advantageous for all.
And most importantly, whether you "use it or not", when manufacturers promote the real and more advanced screen as the common selling point of the ** model, it is definitely a good thing to be encouraged. Because this also means that, at least at this stage, the focus of market competition is to focus on real hardware progress and hardware upgrading. If this strategy can get good feedback, then it can at least be expected to help the entire market quickly popularize and replace new hardware in the coming period. This will have a very positive effect on the interests of consumers and the progress of the industry.
