QLED (Quantum Dot Light Emitting Diode) and OLED (Organic Light Emitting Diode) TVs are two distinct technologies used in modern displays. Here's a comprehensive comparison:
QLED:
1. Uses tiny crystals (quantum dots) to create colors.
2. LED backlight illuminates quantum dots.
3. Color accuracy and brightness improved.
4. Wide viewing angles, but not as good as OLED.
5. Generally more affordable.
OLED:
1. Each pixel emits its own light.
2. No backlight; true blacks achievable.
3. Infinite contrast ratio and wider viewing angles.
4. Faster response time and motion handling.
5. Generally more expensive.
Key differences:
1. Backlight: QLED uses LED backlight, while OLED does not.
2. Black levels: OLED achieves true blacks, while QLED can struggle.
3. Contrast ratio: OLED has infinite contrast, QLED has limited contrast.
4. Viewing angles: OLED maintains color accuracy at wider angles.
5. Price: QLED generally more affordable, OLED more premium.
6. Lifespan: OLED panels may degrade faster than QLED.
7. HDR support: Both support HDR, but OLED's contrast ratio enhances HDR.
8. Color gamut: QLED's quantum dots provide wider color gamut.
Comparison chart:
Feature:

Gaming and motion:
1. OLED: Faster response time (1-2 ms) and better motion handling.
2. QLED: Can exhibit motion blur due to LED backlight.
Brand offerings:
1. QLED: Samsung, Vizio.
2. OLED: LG, Sony, Panasonic.
Conclusion:
Choose QLED for:
1. Affordable price
2. Wide color gamut
3. Good viewing angles
Choose OLED for:
1. True blacks and infinite contrast
2. Wider viewing angles
3. Faster response time and motion handling
Ultimately, OLED offers better picture quality, but QLED provides excellent performance at a lower price.
