The autonomy of most phones is often a problem, regardless of coverage. It is not so simple to last all day with really intensive use and manufacturers are constantly trying to develop technologies that can improve this problem.

Samsung is one of the most important manufacturers in the phone sector as well as in terms of panel production. Its new technologies are designed to improve image quality and consume significantly less energy in OLED displays.

A week ago, the IMID 2024 International Information Display Meeting, which is launched every year in Korea, was held. Samsung’s vice president stated that its new panels would significantly increase the autonomy of its flagship phones. So much so that they would not need to be charged daily. An ambitious promise.

He was referring specifically to the new evolution of Eco² OLED panels, a technology that was born with the Galaxy Z Fold 3 and will be significantly improved in the next generations.

As explained on Anandtech, OLED panels are usually coppery in color and often have problems displaying black due to external reflections, even when their pixels are off.

The reflection here is key for us to perceive black correctly, so a polarizing layer is added to the panel to prevent light from entering and reflecting off of it. This allows only the light emitted by the panel to be what our eyes perceive, not what is reflected by external light.

The problem here is that this polarizer ends up intercepting some of the light emitted by the panel, preventing its true brightness from being appreciated. Samsung’s new idea is to test a panel without a polarizing layer, thanks to new developments in OLED that allow blacks to be displayed without reflections.

According to Samsung, the promised energy savings were 25% savings. The company’s new generations will see improvements in this type of panels, and it is suggested that artificial intelligence itself will help increase consumption (how is not explained). They also took advantage of the conference to talk about their expandable microLED panels, which they have been developing for years but have not yet seen the light of day.

Regardless, Samsung’s goal is clear: Panels are one of the biggest energy consumers in a phone, and improving their efficiency is key to achieving superior autonomy.
