OLED TVs include features to protect against pixel degradation and image retention (burn-in). These typically include:
- Pixel Refresher: Automatically runs after a certain number of hours of use to refresh pixels.
- Screen Shift: Slightly moves the screen periodically to prevent static images from affecting pixels.
- Logo Luminance Adjustment: Detects static logos and reduces their brightness to minimize potential image retention.
It is recommended to allow these features to operate as designed and avoid displaying static images for very long durations at high brightness levels.
