What is the difference between oled and led screen ?
Core Technology Difference
- LED (Light Emitting Diode): Works like a window with blinds. A large backlight shines constantly from behind, and a liquid crystal layer tries to block the light to create dark colors. Because some light always leaks through, blacks look dark gray.
- OLED (Organic Light Emitting Diode): Works like millions of tiny lightbulbs. Each individual pixel creates its own light and color. When a pixel needs to show black, it turns completely off, creating true, pitch-black darkness.
Comparison Points
- Picture Quality: OLED wins with infinite contrast and no light bleed around bright objects.
- Brightness: LED wins because its powerful backlights can get much brighter, making it ideal for sunlit rooms.
- Viewing Angles: OLED wins because the image looks perfect from any seat in the room. LED colors fade when viewed from the side.
- Durability: LED wins because it lasts for many years with zero risk of "burn-in" (permanent ghost images from static icons). OLED requires some care to avoid burn-in.
