The Apple Watch Series 5 uses an LTPO display that refreshes as slowly as once per second to save battery power. This in turn makes it easier to add 120Hz refresh rates to phones, while also enabling longer battery life.
What is LTPO display technology?
LTPO displays allow you to have both a high refresh rate and resolution without turning a smartphone into a battery-sucking rectangle of glass and metal. And the tech is becoming increasingly common in 2021’s Android phones. We first got a proper taste of LTPO displays with the Samsung Galaxy Note 20 Ultra.
So let’s move to know what is LTPO display:
A low-temperature polycrystalline oxide (LTPO) display is a special competitive backplane technology delegated for OLED screens and developed by Apple.
It was initiated with the Series 4 Apple Watch and is a delegate portion of how the modern new Apple Watch Series 5 is adequate to give an (AOD)always-on display experience in the absence of entirely exhausting the battery life.
Using LTPO-style displays allows your screen to vary the refresh rate to save battery life
Now move on to know how it works.
Basically, general or normal LCD and OLED display transfer on low-temperature polycrystalline silicon (LTPS) thin-film-transistors (TFTs) when it arrives at the establishment of the backplane.
When it arrives at AMOLED, it’s contemplated to be more-or-less the advanced but it can be costly.
Even so, the LTPO display tech found in the modern Apple Watch picks out for a combination of both LTPS TFTs and Oxide TFTs.
The latter leverages IGZO (Indium Gallium Zinc Oxide) TFTs instead. In the world of display construction, IGZO is being anxious as the next broad thing.
As we can say that LTPO can be costly and complicated to an extent. IGZO gives a method forward.
They bluster substantially greater electron mobility, which in moves to create them simple to proportion descending into lesser sizes without a loss in performance.
But the question is is LTPO just another name for IGZO?
As the acronym might recommend, LTPO is a hybrid of LTPS and IGZO. You’re obtained a bit of both.
As per Apple, the new Series 5 Apple Watch has “the industry’s only low-temperature polysilicon and oxide display (LTPO), ultra-low power display driver, well-organized power management coalescent circuit and modern new context light sensor.”
It’s that latter constituent here that permits it to give or deliver on the always-on mode where the Series 4 could not.
Samsung Galaxy S23 Ultra rumored specifications
The rumored specifications of the Galaxy S23 reveal that it is packed with a Quad HD+ AMOLED display with LTPO technology. And, hence it will support a 1Hz-120 Hz refresh rate. Also, it is expected that it going to have autofocus -enabled 40-megapixel front-facing camera.
