Understanding TV and Monitor Display Types

When shopping for TVs and monitors, you are likely to encounter various display technologies such as LCD, OLED, and QLED. Understanding the differences between them can help you make more informed purchasing decisions.

Key Differences

1. Subpixels and Colors

   • Most displays use red, green, and blue subpixels, which are the primary colors of light, to create a full range of colors.
   • The purity of these colors can significantly affect the richness and accuracy of the picture.

2. CRTs vs. Modern Displays

   • CRTs, older display technology, struggled with the accuracy of RGB phosphor dots.
   • Modern subpixels are more accurate due to their fixed positions and patterns.

3. LCD Displays

   • Use a white LED backlight through a color filter to create the RGB subpixels.
   • The broad spectrum of white light can lead to imperfect color reproduction.

4. OLED Displays

   • Use individual white OLEDs with color filters.
   • RGB OLED subpixels can be pure, but blue subpixels tend to degrade faster due to energy requirements.

5. Quantum Dots

   • Offer more color-accurate subpixels.
   • Emit pure single color light when struck by a light source.
   • Types include:
     • QLED: Utilizes pure blue LED backlight with red and green Quantum dots for vibrant colors.
     • QD-OLED: Combines OLED's contrast with QLED's color reproduction, featuring high brightness and saturated colors without blue degradation issues.

Additional Considerations

• Quantum dot displays tend to have faster response times, beneficial for watching sports or gaming.
• Consider display technology aspects based on your usage patterns and preferences for color accuracy and contrast.
