Why has the competition over smartphone pixel density reached the end of the line?

For more than a decade, smartphone manufacturers have touted display resolution and pixel density as the most important features of a screen. Even now, phones like the Sony Xperia 1 Mark 4 and Galaxy S22 Ultra consider the use of 4K and QHD displays as a very important advantage. However, since 2015, when 4K and QHD displays first entered the mobile market, this field has undergone many changes.

For more than a decade, smartphone manufacturers have touted display resolution and pixel density as the most important features of a screen. Even now, phones like the Sony Xperia 1 Mark 4 and Galaxy S22 Ultra consider the use of 4K and QHD displays as a very important advantage. However, since 2015, when 4K and QHD displays first entered the mobile market, this field has undergone many changes.

The Galaxy S6 Edge is one of the first phones equipped with a QHD display, which Its pixels were 580 pixels per inch. Meanwhile, Galaxy S22 Plus offers a pixel density of less than 400 pixels per inch due to the use of a larger 6.6-inch screen with FHD resolution. So the question that arises is why companies have abandoned the competition on pixel density?

Why so many phones do not have QHDdisplays?> and 4K?

Among the important reasons for the silent death of QHD and 4K screens, we can mention the high energy consumption of these types of screens. Naturally, the higher the resolution of the display, the more pixels must be used, and as a result, more energy is consumed to turn them on. According to studies, QHD displays consume about 20% more energy than FHD displays.

On the other hand, higher pixel density means an increase in the need for graphics processing power. Many flagship chips face various challenges in order to provide the processing power required for very high resolution based displays. In addition, as you probably know, increasing the pressure on the chip leads to its heating, which also has many complications.

Meanwhile, the fact is that increasing the refresh rate has a greater effect than the pixel density. It is about improving the user experience. Thanks to the use of LTPO displays in some phones, the problem of high refresh rate power consumption has been largely resolved.

Once upon a time, companies said that phones with 4K and QHD displays were ideal for VR headsets. But over the last few years, these types of headsets have disappeared from the market, and as a result, this advantage is no longer important.

We should also note that most of the content that is used with the phone does not use a resolution higher than FHD. . Although some popular streaming services offer 4K resolution for their content, 4K videos are usually not very popular due to the need for very high bandwidth.

Characteristics of a high-quality display

Regardless of the main reason for abandoning the competition for smartphone display pixel density, it is a smart decision. Now, instead of focusing on this issue, companies can pay attention to other features. For example, HDR content is increasing day by day, and the brightness of the screen has become very important.

Years ago, Android phones used low-quality LCD screens with limited color range and low brightness. But these days, many affordable phones are also equipped with high-quality OLED displays. Of course, in the end, the screens used for different phones are not of the same quality, and such a difference is completely normal.

Although Many new phones support a wide and wide color gamut, but a large part of them do not display these colors accurately enough. An improperly calibrated display will display colors warmer or cooler than expected. Some others, although they support the HDR standard, do not display this type of content well.

Therefore, even if the monitor in question has a great resolution, if these features are not used, its quality will be lower than expected. It will be expected. Unfortunately, just considering the hardware specifications of a display, we cannot talk about its performance in the real world. While all companies mention specifications such as resolution and pixel density in their phone ads, almost none of them provide detailed figures on color accuracy. In other words, you should only rely on reliable reviews for the quality of the screen.

Regarding the future of mobile screens, we must say that resolution is no longer as important as it was in the past. Increased energy consumption, increased body temperature, and high pressure on the chip are all factors that reduce the importance of resolution. Considering that many users cannot tell the difference between FHD and QHD resolution, it does not make sense to continue using QHD displays.
