LTPO
Backplane tech allowing 1-120 Hz adaptive refresh to save battery while keeping motion smooth.
Also known as:
LTPO OLED
LTPO display
Full Definition & Technical Explanation
LTPO (Low-Temperature Polycrystalline Oxide) lets a display vary refresh from 1 Hz (static) to 120 Hz (scrolling/gaming). Paired with OLED, it cuts power by ~15-25% without hurting smoothness.
On specs look for Adaptive Refresh Rate: Yes (1-120 Hz) and Type: LTPO OLED. It is closely tied to variable refresh rate and ProMotion (Apple's name for it).

Refresh Rate
How often the screen redraws per second (Hz); higher feels smoother but uses more power.
Display
Variable Refresh Rate
