Galaxy S21 Ultra with power-saving OLED display


Samsung has revealed more details about the new generation of energy-efficient OLED screens in the Galaxy S21 Ultra.

According to the company, the new screen is not only more efficient, but also brighter, as the new OLED screen reduces power withdrawal by 16 percent while also increasing brightness, improving battery life.

The results of the Galaxy S21 Ultra test prove that the screen is very bright, and battery operating times seem to confirm Samsung's claims that the screen is also more efficient.

OLED screens use light-emitting organic diodes, and Samsung has come up with a new organic material that has been developed that helps electrons flow faster and easier across the screen's organic layer.

The smartphone screen is usually one of its most energy-consuming components, so efficiency gains here can have a significant impact on the overall life of the device's battery.

Samsung confirmed that the Galaxy S21 Ultra uses the LTPO screen, but it is not the first Samsung phone to do so.

South Korean electronics giant The Elec reported last year that the Galaxy Note 20 Ultra also used LTPO screens, which are branded as HOP.

However, this week's announcement indicates that the Galaxy S21 Ultra is the first to use the most efficient screens, showing that Samsung has improved the technology further compared to the Note 20 Ultra display.

LTPO screens were used in smartwatches before they appeared on smartphones, with the Apple Watch 4 featuring an LTPO display produced by LG, while Samsung Watch Active 2 used Samsung's LTPO screen.

Apple's upcoming iPhone devices may benefit from Samsung's energy-efficient screen technology.

South Korean electronics industry outlet The Elec said earlier this year that the South Korean company is working to provide LTPO screens for Apple's 2021 iPhone.

According to the report, Apple uses 120Hz LTPO OLED screens on two of the four iPhones for 2021, while the other two have traditional OLED screens.
