These days, smartphones with high-quality displays are on the market, but it is rare for a company to launch even its most expensive flagship with a 4K display. 4K TVs have become the standard among users these days, and while 1080 resolution is not a small issue at all, the increased quality of video content has left people with no reason to view them on FHD or HD monitors. . Of course, 1080P resolution is still very popular among gamers, and this is the main reason why monitor companies continue to market their products with this resolution.
smartphones have a similar fate. This means that the vast majority of them have FHD + displays and only a few of them have QHD + resolution. Of course, these days we see such clarity only in one of the premium flagship models of each company. Not even the standard flagships of the Plus, Plus, and sometimes the Pro models. So that users can see the content better and create positive ads for themselves?
Are there phones with 4K screens?
But before we look at the reasons why 4K screens are not available in smartphones, we should also note that there are currently phones with 4K screens. For example, the first product to hit the market with such a high-quality display was the Sony Xperia Z5 Premium, which launched in 2015 with a super-high-quality display with a density of 806 pixels per inch. Since then, we have seen 4K displays in a number of the company's flagships, but other companies have not followed such an attractive trend.
In a world where many companies are just trying to get users to phones and In general, to attract their products, it will certainly not be difficult to use a 4K display at all, but in practice, the existence of a display with this quality for a smartphone is not very reasonable.
4K display for smartphones is much more than "Retina"
Apple has been using the Retina standard in its handset displays for several years. The American company that even last year was able to launch the iPhone 13 Pro Max with the best display among smartphones (from the point of view of the DisplayMate website), after years of experience, realized that raising and lowering numbers is not necessarily a miracle. Instead, it used a new standard called Retina to display its products. Retina is actually a pixel threshold that the eyes of users can not see more density in a normal viewing angle
Although the use of a smartphone depends entirely on the user's taste and everyone with a different viewing angle to the phone It looks on its own, but in general, at a distance of 10 to 20 inches, we reach the surface of the retina, and we can no longer distinguish higher and better quality with our own eyes. So when a user can view content at 300 pixels per inch with a quality they can't tell the difference from at 800 pixels per inch, why do companies increase the price of the display to 4K?
Using the "Is This Retina" tool, which is an online calculator, has shown that a 6.5-inch display with Panel with 4K resolution reaches the surface of the retina from a distance of 5 inches onwards. It is unlikely that the user will keep their phone in front of them at a distance of less than 5 inches. Normally most users hold their phone from a distance of 10 to 20 inches, which, as mentioned, does not make a difference to a 4K display compared to other monitors.
More pixels consume more powerdisplay severely affects battery life, allowing you to charge your phone more than two or three times in less than 24 hours.
Long battery life is always an important part of your demands. Has formed users and still nothing has changed in this regard. So if companies want to play with numbers only and use 4K displays when we do not need them at all, just for the purpose of advertising on their phones, they have to combine a number of good features to create the balance they need./p>
Smartphone hardware is not ready for 4K quality
Content rendering in 4K resolution It is not simple and requires very powerful hardware resources. Even the latest gaming consoles or very powerful graphics are sometimes not able to do that. This is why FHD resolution is still the gamers' favorite resolution, and few people are turning to buying a 4K display. Ignored. But it should not be forgotten that the power required to render content in 4K resolution is about 4 times more than the phone needs to render content in FHD resolution. With the exception of videos and 2D content such as web pages or images, many other content needs to be resized to less than 4K resolution. Because it does not have this quality natively.
Even when a content is natively of 4K quality and displayed on our phone's 4K display, it is exactly the same in terms of quality. Which we see on the 1080P or 1440P screen of our phone at a normal distance. So with the power of today's smartphones, it does not make much sense for companies to use 4K displays in them. It also has a much higher price. Imagine an OLED display these days accounting for at least a third of the price of a phone. Now, even if this display is 4K, it will definitely put a lot of costs on the hands of manufacturers and consequently users. These companies need to be able to balance the various features and the price of a phone. Otherwise they will definitely have trouble selling. Because in the end we will see a useless phone with a 4K display that costs more than $ 1,000, if it could be used for lower quality, a few hundred dollars in cost savings or that cost to improve other parts.
What do you think? Would you like to use a smartphone with a 4K display or do you think the quality is quite satisfactory?
