IPS vs TN vs VA

  • IPS
    • Pros
      • Outstanding color accuracy and consistency
      • Maximum available viewing angles
      • Response times sufficient for most users
      • Virtually eliminates color/contrast shift seen with some VA displays
    • Cons
      • Below average static contrast ratio
      • Potential white glow from off-angles when viewing dark content. Usually only an issue with lower-end & off-brand IPS monitors
      • More motion blur than a TN monitor
      • IPS Monitor Best Uses:
    • When
      • Color-critical professional applications
      • Technology enthusiasts
      • Higher-level business/home use
      • Gamers who value image quality over response time
  • TN
    • Pros
      • Rapid response time
      • Lower price
      • Sufficient contrast for most business/general purpose use
      • TN Monitor Drawbacks:
    • Cons
      • Most restrictive viewing angles, especially in vertical plane
      • Not recommended for color-critical applications
    • When
      • Gaming
      • Entry-level
      • General use
  • VA - P-MVA, S-MVA, AMVA (Advanced MVA).
    • Pros
      • Maximum available viewing angles
      • High contrast ratios
      • Response times sufficient for most users
      • Mid-range to high-end pricing options
    • Cons
      • Response times slower than TN
      • Off-center contrast shift with some models
      • VA Monitor Best uses:
    • When
      • Movies
      • Photography/Videography
      • Content creation
      • Home use
      • Gamers who value image quality over response time
  • OLED
  • LCD
    • 使用背光 - 可能发光有误
    • 动态图像模糊
  • OLED
    • 主动 - 避免屏幕发光 - 黑色更黑
    • 比 LCD 更贵
  • CRT
  • TFT

DCR

  • Dynamic Contrast Ratio
  • 对比度优化技术,自动判断画面整体亮度, 通过减弱较暗区域亮度,有效地对不同色阶层次精准还原,使画面细节更清晰,层次更分明。
