The Apple Watch is often a kind of testing ground for Apple in some respects. Being a smaller device, the company can experiment “on a small scale” with new technologies. This is what happened for example with the pressure on the screen and the OLED panel, two technologies that later came to the iPhone. Maybe the next thing we see is the LTPO technology that allows the Apple Watch screen to save much more energy than a normal OLED panel.
According to a report from The Elec, Apple plans to adopt the low-power, low-temperature polycrystalline oxide (LTPO) technology from the Apple Watch to the iPhone . No dates have been given, although they indicate that it could be in the short term. It seems that everything will depend on how the conditions are negotiated with Samsung Display, which is the main manufacturer of the iPhone’s OLED panels. There is little point in Apple wanting to adapt a new technology if there is no one to manufacture it.
Unfortunately, the report does not go into specific details about when this technology could be adopted . It is possible that the company has been working on it for quite some time and we will see it in the next generation of the iPhone in 2020 for example. But it may also be years away, or it may not be adopted at all. In the end, there is hardly any information about it.
The OLED LTPO panel is the one found in the Apple Watch Series 4 and Apple Watch Series 5. The back layer is responsible for turning the individual pixels on the screen on and off. While OLED panels generally allow you to turn off individual pixels, an OLED LTPO panel can save up to 15% more energy compared to an OLED LTPS panel, which is currently available on iPhone. Why? Because reduces the refresh rate from 60 Hz to 1 HZ when the clock is idle.
In Apple’s words about this technology in the Apple Watch:
The adoption of LTPO technology has made it possible for Apple to significantly increase the battery life of the clock without adding much more battery capacity. In fact, Apple indicated that it is the technology that has made it possible for them to implement the “always on display” technology of the Apple Watch Series 5.
In AppleApple Watch Series 5, analysis: always on
Will we see it on the iPhone? If so we could have a better battery saving and consequently increase the autonomy of the phones. As always, it will depend on several factors such as production capacity, the cost of this technology and its stability. We will know in the future.
