What these specs mean
At phone viewing distance (around 15 cm / 6 inches), pixel density is the first thing you notice — above 300 PPI individual pixels disappear and text looks printed rather than pixelated. Refresh rate controls how smooth scrolling and games feel: 60 Hz is the long-standing baseline, 90–120 Hz noticeably cuts motion blur, and LTPO OLED panels can ramp from 1 Hz up to 120 Hz to save battery on static content. OLED's per-pixel contrast also makes blacks look genuinely black, which matters for dark-mode reading and overall battery behavior.
Xiaomi's HyperOS flagships pair LTPO AMOLED panels — often with peak brightness above 3,000 nits and full Dolby Vision HDR — with aggressive 120 Hz refresh targets. Xiaomi tends to push raw panel specs at a lower price point than Samsung or Apple, trading polish for sheer hardware headroom.
