Samsung's Galaxy S21 Ultra features a new low-power OLED display

When Samsung launched the Galaxy S21 Ultra, it talked about how the device’s screen supports refresh rates of 120Hz at both full HD and Quad HD resolutions. What it didn’t say until now, however, is that the S21 Ultra serves as the debut device for the tech giant’s new low-power OLED display technology. Samsung has revealed that the flagship phone uses OLED display that reduces power consumption by up to 16 percent.

OLEDs don’t need a separate light source unlike other screen technologies — instead, it depends on organic carbon-based material that emits visible light when electricity is applied. Samsung found a way to make electrons flow faster across its OLED’s organic layers, and the company says that allows the display to “create brighter light while consuming less power.”

5G devices typically use more battery than their predecessors. In addition to the modem’s power needs, newer phones’ more advanced components may be power—hungry, as well. People might also use their devices for video streaming more frequently than before, since having a 5G connection could make it easier to watch shows and movies on the go.

Manufacturers can only increase their phones’ battery capacities to a certain extent, so coming up with new ways to make their devices more power efficient is a must. Samsung explains that the display planel is “one of the most important components affecting a smartphone's total power consumption.” That’s why equipping the S21 with a low-power OLED technology can “significantly impact smartphone usage time.”

we achieve a two-fold increase in operational stability at the same brightness as a reference conventional device while simultaneously extracting 16 per cent of the energy from the plasmon mode as light. Our approach to increasing OLED stability avoids material-specific designs19–22 and is applicable to all commercial OLEDs that are currently used for lighting panels, televisions and mobile displays.
UDC Develops Nanopatch Antenna for OLED Lighting
Nano-sized particles are coated on top of CPL to maximize the light coming out from the device, but the technique does not produce the uniform thickness displays require for a straight light from the device surface as collimated as possible to maximize the resonance effect, but these particles will scatter the light. This technology might be suitable for lighting applications, but it won't work well for displays.
