Samsung’s Galaxy S21 Ultra with first new power efficient OLED display


Samsung’s latest flagship, the Galaxy S21 Ultra, is its first phone to introduce a new power-efficient OLED panel from Samsung Display. In a press release, Samsung says the new display consumes 16 percent less power thanks to “just-developed organic materials”, meaning “electrons flow faster and more easily into the organic layer of the display . “

“In other words,” Samsung explains, the technology means that “OLED panels can produce brighter light while consuming less power, thereby improving battery life.” A smartphone’s display is usually one of its most power hungry components, so achieving efficiency here can have a major impact on the overall battery life of the device. In our review, we commented that the S21 Ultra has excellent battery life that lasts “beyond a full day”.

Samsung confirmed The ledge That the S21 Ultra uses an LTPO (aka low-temperature polycrystalline oxide) display, but it is not the first Samsung phone to do so. Last year, elephant It was reported that Samsung’s Galaxy Note 20 Ultra also uses LTPO display panel, which is in the form of Samsung brand HOP (Hybrid Oxide and Polycrystalline Silicon). However, this week’s announcement stated that the S21 Ultra is the “first” to use more efficient panels, suggesting that Samsung Display has further refined the technology than the Note 20 Ultra.

LTPO displays have been used in smart watches before appearing in smartphones. elephant Note that the Apple Watch Series 4 had an LTPO display manufactured by LG, while Samsung’s Galaxy Watch Active 2 used an LTPO display manufactured by Samsung Display.

If the report is accurate, Apple’s next major iPhones may soon benefit from Samsung Display’s power-efficient panel technology. earlier this year, elephant Reported that the South Korean company is in the line to supply LTPO panels for Apple’s 2021 iPhones. According to the report, Apple will use a 120Hz LTPO OLED display in two of its four iPhones in the second half of the year, while the remaining two will have more traditional OLED panels.
