The next-generation high-end Xperia phone, presumably known as the Sony Xperia 1 V, appears to utilize some new display technology (at least new for the Xperia range). Polycrystalline oxide enables additional power-saving features. LTPO displays are available with variable refresh rates, which can extend smartphone battery life.
“LTPO” is already a familiar term in the smartphone world, as devices like the Xiaomi 12 Pro and Apple iPhone 14 Pro feature LTPO displays, but Sony has so far made no attempt to bring the technology to its Xperia lineup. I have avoided using it. The Xperia 1 IV comes with a 4K-capable OLED panel with a fixed 120 Hz refresh rate, making the Xperia 1 V the first device to feature the new variable rate display technology.
However, the source of this information (via Weibo smartphone digestIt also claims that the Xperia 1 V’s LTPO display may not be able to take advantage of the power-saving variable refresh rate when running at 4K resolution. This doesn’t seem to make much sense as it would be pointless to adopt and lock in new tech at a particular refresh rate just to enable 4K on the Sony Xperia 1 V. But it could work well for an LTPO panel and help save power on the Mark 5 variant of the Xperia 1 when displaying FHD content.
