1. Pochopenie typov obrazoviek a technických rozdielov

Smartfóny Redmi sa dodávajú v rôznych modeloch s rôznymi technológiami obrazovky. Ak chcete urobiť najlepšie rozhodnutie o kúpe, Pozrime sa bližšie na to, ako sa technológie LCD a OLED líšia a ako ich Redmi aplikuje vo svojich produktových radoch.

1.1 LCD vs. OLED: Prehľad technológie

LCD (Kvapalina) a oled (Organická dióda vyžarujúca svetlo) predstavujú dve hlavné zobrazovacie technológie v smartfónoch.

LCD sa spolieha na podsvietený panel, ktorý osvetľuje molekuly tekutých kryštálov.
OLED používa organické zlúčeniny, ktoré vyžarujú svetlo nezávisle, eliminuje potrebu podsvietenia.

Každý prichádza s odlišnými výhodami a kompromismi.

Výhody:

Nižšie náklady

Cannot achieve pure black
Lower contrast ratio
Typically thicker than OLED
Limited viewing angles compared to OLED

1.3 Pros and Cons of OLED Screens

Výhody:

Higher contrast and true blacks
Better color saturation
Tenšie a pružnejšie
Podporuje funkcie ako Always-On Display
Faster pixel response time (great for gaming)

Nevýhody:

Vyššie náklady
Možné blikanie s nízkym jasom (PWM)
Potential for burn-in after long-term use
