At first glance, the new Galaxy S25 series smartphones do not differ much from their predecessors, but the author of the YouTube channel The Tech Chap drew attention to the use of a new display technology in them, which replaced LTPO.
What else is known
Thanks to LTPO (Low-Temperature Polycrystalline Oxide) technology, OLED screens can dynamically adjust the refresh rate from 1 to 120 Hz depending on the displayed content. In fact, it has become the standard for flagship smartphones in recent years. Samsung also used this technology, but in the Galaxy S25 models it switched to its own development called HOP 3.0 (hybrid oxide and polycrystalline silicon).
HOP 3.0 is a more advanced alternative to LTPO for improved energy efficiency, although the company does not provide specific figures. In addition, such screens respond more accurately to touch, which reduces response time, and also better adjust brightness in response to changes in ambient light.
