TFT (Thin-Film Transistor) is a foundational technology for LCD screens, where each pixel is controlled by a thin-film transistor to improve display quality. While AMOLED and TFT-LCD both dominate modern display markets, their core principles and performance differ significantly. Here’s a detailed comparison:
AMOLED: Self-emissive technology. Each pixel emits light independently via organic materials, eliminating the need for a backlight or liquid crystal layer.
2. Core Advantages
Aspect
AMOLED
TFT-LCD
Contrast Ratio
Theoretical infinite contrast: Pixels can turn off completely, rendering pure blacks (ideal for dark scenes like night skies).
Limited (typically 1000:1 to 3000:1): Backlight leakage makes blacks appear grayish.
Color Performance
Wider color gamut (DCI-P3/BT.2020 support) and higher saturation, with vibrant HDR rendering.
