- Limited viewing angles compared to OLED
1.3 Pros and Cons of OLED Screens
Advantages:
- Higher contrast and true blacks
- Better color saturation
- Thinner and more flexible
- Supports features like Always-On Display
- Faster pixel response time (great for gaming)
Disadvantages:
- Coût plus élevé
