Samsung’s Galaxy S21 Ultra is the first with a new energy-efficient OLED display



Samsung’s latest flagship, the Galaxy S21 Ultra, is the first phone with Samsung’s new energy-efficient OLED panels. In a press release, Samsung said the new display consumes 16 percent less energy thanks to “freshly developed organic material,” which means “electrons flow faster and easier through the organic layer of the display.”

“In other words,” Samsung explains, the technology means that “OLED panels can create brighter light while consuming less power, which improves battery life.” The smartphone’s display is usually one of the most thirsty components, so increasing efficiency here can have a big impact on the overall battery life of the device. In our review, we noted that the S21

Ultra has excellent battery life, which lasts “all day”.

Samsung confirmed On the edge that the S21 Ultra uses an LTPO (also known as low temperature polycrystalline oxide) display, but is not the first Samsung phone to do so. Last year, The Elec reported that Samsung’s Galaxy Note 20 Ultra also uses LTPO display panels, which Samsung marks as HOP (hybrid oxide and polycrystalline silicon). This week’s announcement, however, says that the S21 Ultra is “the first” to use more efficient panels, suggesting that Samsung Display has further improved the technology compared to the Note 20 Ultra.

Before appearing on smartphones, LTPO displays were used in smartwatches. The Elec notes that the Apple Watch Series 4 includes an LTPO display manufactured by LG, while Samsung’s Galaxy Watch Active 2 uses an LTPO display manufactured by Samsung Display.

If the reports are accurate, Apple’s next leading iPhone may soon benefit from Samsung’s energy-efficient panel technology. Earlier this year, The Elec announced that the South Korean company is about to deliver LTPO panels for Apple’s iPhone 2021. According to the report, Apple will use 120Hz LTPO OLED displays in two of its four iPhones in the second half of the year, while the other two will have more traditional OLED panels.
