LTPO (low-temperature polycrystalline oxide) displays offer a number of advantages over OLED displays, including:
- Variable refresh rates: LTPO displays can dynamically adjust their refresh rate based on the content being displayed, which can save battery life. For example, a static image can be displayed at a lower refresh rate than a video, without any noticeable impact on image quality.
- Always-on displays: LTPO displays can be used to implement always-on displays without sacrificing battery life. This is because LTPO displays can be set to a very low refresh rate when the display is idle, which minimizes power consumption.
- Thinner and lighter displays: LTPO displays are typically thinner and lighter than OLED displays, making them ideal for mobile devices.
- Improved brightness and contrast: LTPO displays can offer improved brightness and contrast levels compared to OLED displays.
Overall, LTPO displays offer a number of advantages over OLED displays, including better battery life, always-on displays, thinner and lighter displays, and improved brightness and contrast.
Here are some specific examples of how the advantages of LTPO displays can be seen in real-world use:
- The iPhone 13 Pro and Pro Max use LTPO displays to achieve an always-on display without sacrificing battery life.
- The Samsung Galaxy S22 Ultra uses an LTPO display to dynamically adjust its refresh rate between 1Hz and 120Hz, depending on the content being displayed. This results in improved battery life and smoother performance.
- The Apple Watch Series 7 uses an LTPO display to achieve an always-on display with all-day battery life.
LTPO displays are still a relatively new technology, but they are quickly becoming more popular in high-end smartphones and other mobile devices. As the technology continues to develop, we can expect to see LTPO displays become even more widespread and affordable.
