Beyond OLED panels; What future awaits mobile monitors?

BingMag.com <b>Beyond</b> <b>OLED</b> <b>panels;</b> <b>What</b> <b>future</b> <b>awaits</b> <b>mobile</b> monitors?

OLED displays have become a common feature among many mid-range and even affordable phones in the last few years. Although the quality of all old panels is not the same, but this technology has reached such a maturity that we no longer see the phenomenon of pixel burns as in the past. With these advances, will a new technology soon overtake the old displays? If not, What new features will the next generation of old panels offer? Here's the future of mobile displays.

Whether microLED or mini-LED Are they becoming ubiquitous among phones?

The first microLED displays appeared in 2018, and we have been waiting for this technology to be used for mobile displays ever since. MicroLED displays are made up of millions of tiny LEDs in the micrometer range. Like the old panels, in these displays, each of these LEDs can be turned on and off separately, and this approach means providing a deep black color. Other benefits of this technology include higher brightness, higher pixel density, lower power consumption, and reduced downtime.

Although it has been about 4 years since this type of display was released, companies have not yet been able to significantly reduce production costs for widespread use. All in all, making microLED displays is by no means an easy task because millions of microscopic LEDs have to be placed next to each other and connected. On the other hand, the benefits of this technology for mobile monitors are not worth the huge costs. That's why companies like Apple plan to use the technology first in augmented and virtual reality gadgets, as well as wearable gadgets.

What can LED say? Mini-ED displays are basically the same as LCD displays, but different technology is used for the backlight. Because of this difference, they can provide more contrast and brightness than conventional LCD monitors, and are cheaper to produce. Unfortunately, mini-LED displays are not yet widely used by companies. Currently, the new MacBook Pro and an iPad Pro are the only major gadgets that take advantage of this technology. Although in 2018 there were rumors that Xiaomi and Huawei phones will use this technology, but these rumors never came true.

OLED display product lines seem to be so mature that, at least for small screens, leaving them aside to take advantage of newer technologies is not very economical. It seems that even Apple does not want to use mini-LEDs for the next generations of iPads, and according to new reports, different models of iPads with OLED panels will be on the market in a few years.

Displays QD-OLED How lucky are they?

Samsung unveiled Quantum Dot Old (or QD-OLED) technology at CES 2022. Simply put, QD-OLED TVs combine the deep black color of old displays with the creation of a wide range of colors in quantum dot technology. This technology can be a good platform for wider color spaces such as Rec. 2020 and on the other hand has more to say in terms of maximum brightness than OLED panels.

However, the benefits of this technology do not necessarily apply to mobile monitors. The vast majority of older TVs on the market use LG's W-OLED panels, dating back to the 2009 purchase of Kodak patents. These panels use white light and color filters to display green, red, and blue. But the same process of filtering the backlight leads to a loss of some brightness and colors. But QD-OLED displays make colors much more attractive and also have more to say about brightness.

On the other hand, Samsung AMOLED panels used for mobile monitors typically have a PenTile RG structure. -BG based on red, blue and green subpixels. This technology does not use any type of filter and therefore has a better performance than the panels used in TVs. Although QD-OLED technology will be further improved in the near future, it does not appear to be as beneficial as it claims.

BingMag.com <b>Beyond</b> <b>OLED</b> <b>panels;</b> <b>What</b> <b>future</b> <b>awaits</b> <b>mobile</b> monitors?

Of course, we're not saying that the old panels used in smartphones are perfect. At PenTile displays have twice as many green subpixels as red and blue subpixels. That's why the effective resolution - the resolution that our eyes see - is usually lower than What is advertised. In this regard, QD-OLED panels with integrated matrix for red, blue and green colors work better than mobile monitors.

Samsung announced in 2013 that the reason for using the PenTile sub-pixel layout is low power consumption Returns green subpixels. Our eyes are also more sensitive to green than red and blue, so in the PenTile layout green sub-pixels use less energy to achieve a certain level of brightness. Reducing power consumption also reduces the likelihood of pixels burning.

As a result, Samsung will soon be scrapping PenTile panels for mobile displays. Also, not enough information has been published about the energy consumption and durability of QD-OLED displays. At present, Samsung only produces large displays based on QD-OLED technology, and there is no word yet on the use of this technology for phones, tablets and laptops. According to published reports, the production efficiency of these displays is very low, about 30%. Meanwhile, the production efficiency of AMOLED displays is around 80 to 90%. Thanks to this high efficiency, Samsung has been able to lower the price of its AMOLED displays over the years and make them available to various companies. But like other new technologies, QD-OLED displays are likely to improve in price and production in the not-too-distant future.

Apart from emerging display technologies, fortunately the current AMOLED panels They are also constantly evolving and improving. Every year, Samsung uses better mobile screens that have more to say than their predecessors. However, these improved displays are first used for flagship phones and later for non-flagship phones.

For example, we can mention the Galaxy S21 Ultra, which was released last year. The phone was the first to use an OLED panel based on new materials, for which Samsung chose the name M11. According to studies, the energy consumption of new light emitters compared to the previous generation has decreased by 25 to 30 percent, which is a significant reduction.

However, the S21 and S21 Plus do not use this technology, which may have been decided to reduce manufacturing costs. A year later, now the S22 Plus uses the same technology alongside the Ultra model, but we do not see the use of this new panel in the standard model. The Korean news agency TheElec reported some time ago that by 2022, the panels on many of Samsung's low-cost handsets will consume less power thanks to the use of M9 headlights instead of the M8 generation.

But What does all this specialized explanation mean for Have regular users? First of all, we must mention the reduction of energy consumption. Assuming that the new chips do not put more pressure on the battery, the battery life of the phones will probably improve day by day in the coming years. On the other hand, improvements in variable rate refresh technology also play an important role in reducing energy consumption. For example, the refresh rate of some phones, such as the Galaxy S22 Ultra and Oppo Find X5 Pro, is reduced to 10 Hz, but many phones still do not use this feature.

Although these improvements are very important for mobile screens But on the other hand, we should not overlook their importance for clamshell phones. At the moment, clamshell phones have no choice but to use old technology for their displays. But overall, the old monitors are not making significant progress in terms of resolution and color gamut, and we should look forward to newer technologies in this area.
