    Study Notes

    Burn-in in PDPHE (Plasma Display Panel High-Speed Electron)

    Definition:

    • Burn-in, also known as image retention, is a phenomenon where a static image remains on the screen for a prolonged period, even after the image has been changed or removed.

    Causes:

    • Phosphor degradation: The phosphor coating on the plasma display panel can degrade over time, leading to a permanent impression of the static image.
    • Ion bombardment: The intense ion bombardment on the phosphor surface can cause damage, resulting in image retention.

    Effects:

    • Permanent image retention: The static image can remain on the screen even after the power is turned off.
    • Decreased panel lifespan: Burn-in can reduce the overall lifespan of the plasma display panel.
    • Decreased image quality: Burn-in can cause a decrease in image quality, leading to a loss of contrast and color accuracy.

    Prevention methods:

    • Screen savers: Running screen savers can help prevent burn-in by changing the image on the screen periodically.
    • Image rotation: Rotating the image on the screen can help prevent burn-in by reducing the static nature of the image.
    • Pixel shifting: Some displays can shift the image by a few pixels to prevent burn-in.
    • Turning off the display: Turning off the display when not in use can help prevent burn-in.

    Mitigation techniques:

    • Burn-in correction: Some displays have built-in burn-in correction features that can help reduce the effects of burn-in.
    • Image washout: Some displays can perform an image washout, where the screen is filled with a white or gray image to help remove the static image.
    • Panel replacement: In severe cases, the plasma display panel may need to be replaced to prevent further burn-in.
