Most smartphones in 2023 offer some form of high refresh pace , whether it ’s 90Hz , 120Hz or even 165Hz , but this has often come at the price of overall battery life .
That ’s all jell to change with the introduction of LTPO 3.0 AMOLED display that expect to dramatically improve power efficiency while still delivering the buttery - politic carrying into action consumers have add up to require .
It ’s a primal feature in plenty of 2022 and 2023 flagships including theiPhone 14 Pro , OnePlus 11andSamsung Galaxy S23 Ultra , but what exactly is LTPO 3.0 and is it really right than standardAMOLED panel ?
We explain all you take to know about LTPO 3.0 show mightily here .
What is LTPO 3.0?
LTPO 3.0 is the latest version of LTPO technology available on certainhigh - end smartphones . In a nutshell , the technical school allows video display to dynamically interchange between refresh rate without the need for an additional component between the graphics controller and the GPU . While initial LTPO displays were define to 10Hz-120Hz , the more late LTPO 2.0 and LTPO 3.0 offer 1Hz-120Hz financial support .
This has the potential drop to greatly meliorate the energy efficiency of the showing , arguably the biggest reference of world power draw on a smartphone . This allows the show to , for model , swing the refresh charge per unit down automatically when looking at static mental image and outright storm it up to 90- or even 120Hz when scrolling through menus or acting games where supernumerary frame are always welcome .
It can also drop as minuscule as 1Hz when exhibit element like an always - on display , greatly meliorate the energy efficiency of the dialog box .
For circumstance , standard organic light-emitting diode panels do n’t reserve for the dynamic adjustment of refresh rates without an additional component installed , which uses yet more power . It ’s the chief reason that many phones you ’ll find will either flip-flop between 60Hz,90Hzand120Hz , whereas LTPO display can range anywhere from 1Hz up to 120Hz .
Is an LTPO display different from a standard OLED smartphone display?
LTPO is technically a tweaked version of OLED , but the two are different . As advert , standard OLED instrument panel ca n’t dynamically adjust the refresh rate without an additional component between the graphics restrainer and GPU , whereas LTPO displays do n’t need this portion .
It ’s down to the means the LTPO displays are built , and more specifically , the type of backplane used . For context , the backplane essentially controls how each pixel acts , and is consist of thin film transistors known as TFTs . LTPO showing are made from a compounding of low - temperature polycrystalline silicon ( LTPS ) TFTs and indium gallium zinc oxide ( IGZO ) TFTs , where the former brings improved Energy Department efficiency while the latter enables the dynamic refresh rate .
What are the benefits of an LTPO display?
As we ’ve alluded to , the main welfare of using an LTPO display over a standard OLED showing is improved power efficiency , specially with high refresh rate displays . It ’s still true that OLED panel are more battery favorable than LCDs , but LTPO take this a step further .
The improved technology permit the display to dynamically adjust the refresh rate look on what ’s happening on screen , with the power to leave out down to a battery - friendly 1Hz when the always - on display is in use and ramp up to up to 120Hz instantly to provide that larder smooth , antiphonal feel of a profligate blind . This allows you to full bask the high refresh charge per unit while not hammering the stamp battery by constantly rendering at 120Hz .
