Low temperature polycrystalline oxide. Probably these words united under the acronym LPTO doesn’t tell you much, but it’s a technology that has already been used by Apple in its Apple Watch Series 4 and Series 5, and will soon reach smartphones like the Galaxy Note 20, including concept images (unofficial ) already described with this image design.

This is what a consultant specializing in this field said, who revealed that the future Samsung Galaxy Note 20+ will have an LPTO screen which will stand out above all for benefiting from high refresh rates (in this case, 120 Hz) without triggering energy consumption. This provides a solution to this drawback of those 90Hz and 120Hz displays which “eat up” the battery faster than when used at 60Hz.

120 Hz screens without (as much) compromise

Ross Young, CEO of Display Supply Consultants (DSCC), has revealed these days how Samsung itself has “confirmed” that the Galaxy Note 20+ will support 120 Hz on its screen, but the base model of this terminal, the Galaxy Note 20, will retain an LPTS screen (Low temperature polycrystalline silicon) at 60 Hz.

The key is to use LPTO technology. As Young explained, 120 Hz LPTS displays can be used, “but they consume a lot of power”.

This is something that we see in terminals that integrate these types of screens with high refresh rates: they either lower the resolution while doing so, or they have operating modes that detect when to activate or not that frame rate. refreshment. The goal is to try to reduce energy consumption at any time.

Between 5 and 15% more efficient than traditional screens

With LPTO technology, it is precisely possible to use displays with high refresh rates and high power consumption that is between 5 and 15% lower than that of LPTS panels according to IHS.


This layer can be applied to OLED and LCD panels, but its integration must be particularly visible on OLED and AMOLED screens that are flooding our electronics right now.

Apple has already used this type of technology in the Apple Watch Series 4, which has improved the screen efficiency of these smartwatches, and has done something similar with the Apple Watch Series 5, which according to the company had the only screen with this technology. as well as new controllers and energy management systems that allowed for the first time to have a screen always active in these models.

Other leaks that take us to the details of the future Galaxy Note 20 and Note 20+ indicate that there will be no noticeable changes in internal specs or in the camera system.

The diagonals will change: the Note 20 will drop to 6.42 inches and have a screen resolution of 2345 x 1084 pixels, while the Note 20+ will have a diagonal of 6.87 inches and a resolution of 3096 x 1444. L no LPTO technology in the basic model will allow its cost to be significantly lower, although as they point out in Sam Mobile, making a more affordable Galaxy Note with S Pen was something Samsung had done before with the Galaxy Note 10 Lite, for example.
