Samsung’s latest flagship, the Galaxy S21 Ultra, is the first phone with Samsung displays new energy-saving OLED panels. In a press release, Samsung says that the new display uses 16 percent less electricity thanks to a “newly developed organic material”, which means that “electrons flow faster and easier over the display’s organic layer”.
“In other words,” explains Samsung, the technology means that the OLED panels can produce brighter light while using less power, which improves battery life. “The display of a smartphone is usually one of the most power-hungry components. Therefore, increases in efficiency can have a major impact on the overall battery life of the device our ratingWe found that the S21 Ultra has excellent battery life that lasts “beyond a full day”.
Samsung confirmed to The edge that the S21 Ultra uses an LTPO (also known as a Polycrystalline low temperature oxide), but it’s not the first Samsung phone to do this. Last year, The Elec reported The Samsung Galaxy Note 20 Ultra also used LTPO display panels, which Samsung calls HOP (Hybrid Oxide and Polycrystalline Silicon). However, this week’s announcement states that the S21 Ultra will be the “first” company to adopt more efficient panels, suggesting that Samsung Display has further refined 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 has an LTPO display made by LG, while the Samsung Galaxy Watch Active 2 uses an LTPO display made by Samsung Display.
If the reports are correct, Apple’s next flagship iPhone could soon benefit from Samsung Display’s low-power panel technology. Earlier this year The Elec reported The South Korean company is ready to ship LTPO panels for Apple’s 2021 iPhones. 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.
