Samsung Display is one of the biggest innovators in the industry. Among the wildest concepts the division has worked on over the years is the extendable display. And on top of that, there's another one that uses 50% less battery power. So the revolution is about to fall. 

There is a conference this week IMID 2024 and Samsung here she performed its latest generation of stretchable display, which has continued to evolve and improve since we were first able to see it (which was back in 2017). It is based on micro LED technology and can be extended by 25%. In other words, it can be stretched up to 1,25x or deformed in some way and it will always return to its original shape. You can see how it works in the video below, which simulates the appearance of the South Korean island of Jeju. 

This almost magical micro LED panel has a pixel density of 120 pixels per inch, which may not sound too impressive compared to today's common displays found in mobile phones. For example Galaxy The S24+ has 513 ppi. And Samsung's OLEDoS screen for VR, introduced in January this year, has 3 ppi. However, this screen is unlikely to be used in smartphones or headsets.

One of the reasons stretchable displays have not yet become mainstream may be that they are too fragile for commercial products. Another reason may be that the technology used is also quite expensive. Finally, as impressive as this technology is, it's quite difficult to come up with really useful applications to justify its cost. However, this does not apply to the second novelty.

Is the era of energy-saving displays coming?
Samsung is developing an OLED display without a polarizing film, which is supposed to usher in an era of energy-saving panels, whose energy consumption will be half that of current phone displays. This is exactly what Samsung Display Vice President revealed during the keynote speech "Everlasting Evolution of Display with AI" at the ongoing IMID 2024 exhibition. 

This is an extremely interesting innovation if only because phone displays (together with processors) have the greatest demands on the phone's battery. A display with 50% less power consumption will thus significantly extend smartphone battery life, or batteries can be made smaller, making the entire device smaller or making more room for additional hardware.

The third possibility is that the 50% of the battery will be taken by something completely different, and it is not difficult to guess what it will be. We are, of course, talking about artificial intelligence. It will probably be more about finding an ideal balance between these options so that the endurance of future smartphones does not deteriorate in any way. No one would probably want that. But in every respect there is something to look forward to.
