Welcome to the LTPO era…

According to CINNO Research’s most recent research, LTPO technology is projected to become standard in high-end mobile phones. In addition, OLED smartphone penetration in the Chinese market is predicted to reach 43% by 2025. This is critical, yet most users will be unfamiliar with these words. They may not even realize whether or not their cellphones employ these technologies.

Apple introduced LTPO technology to the iPhone last year. It was so well received that several Android smartphone manufacturers opted to develop their own versions with LPTO displays. This technology is now being used by an increasing number of Android smartphone OEMs, boosting its penetration rate within the Android camp.


LTPO is an acronym for Low-Temperature Polycrystalline Oxide. For small-size OLEDs, the two major backplane technologies are LTPS and IGZO, with LTPO being able to produce a broad variety of dynamic refresh rates. To put it another way, it combines the benefits of both LTPS and IGZO technology.

Consider the following scenarios to have a better understanding of what this technology can achieve. Allow LTPS to be utilized in the drive circuit to reduce drive current and voltage. Also, because IGZO has a lower leakage current, it should be in charge of the switch circuit to obtain a lower refresh rate. As a result, OLED’s possible refresh rate range expands.

A greater screen refresh rate and touch sampling rate, as we all know, might result in a delicate and smooth user experience. We do know, however, that a greater refresh rate consumes more power. In some ways, LTPO screen technology arose to address this issue. It is also experiencing an evolutionary improvement of technology, from the first worldwide 90Hz and 120Hz to the subsequent dynamic adaptability.

The screen refresh rate is automatically lowered while showing low frame rate material such as films, photos, texts, and so on. This will assist the phone in conserving energy and extending its battery life. The phone will switch to the appropriate mode when a high refresh rate is necessary, such as when playing games. This will result in faster battery depletion, but it will deliver the optimum performance for a concrete usage case.

All OLED screen smartphones employing LTPO technology enable a 120Hz adaptive refresh rate, according to CINNO Research. They also discovered that by 2022, it will be a standard feature on flagship phones. With increasing LTPO production capacity, the technology is likely to exceed LTPS and become the standard configuration of high-end smartphones.

According to CINNO Research, in China’s OLED smartphone industry, flexible OLED products utilizing LTPO technology would exceed those using LTPS technology by 2025.
