pixelrefresh

Pixelrefresh is a term used in display technology to describe a maintenance procedure aimed at preserving image quality on certain screens, particularly OLED panels. The core idea is to rebalance the wear of red, green, and blue subpixels and to reduce image retention or burn-in that can occur with prolonged display of static content. Pixelrefresh routines are part of broader panel maintenance practices and are not image processing, but rather a calibration-like process for the display hardware.

How a pixelrefresh works can vary by manufacturer and model. In many implementations, the process runs a controlled sequence across the panel, occasionally re-calibrates subpixel voltages, or re-establishes uniform pixel states to prevent uneven aging. The routine can be automatic, triggered after extended use or when idle, or manually started by the user through the device’s settings or companion software. The duration can range from a few minutes to longer periods during which the display may be dimmed or temporarily unavailable.

Effectiveness and limitations: Pixelrefresh can help mitigate mild image retention and slow the progression of burn-in on OLED and related displays, but it is not a guaranteed cure for permanent discoloration or deep-set burn-in. It is most effective as a preventative maintenance measure when used in conjunction with good usage habits, such as avoiding long static images and enabling auto-brightness where appropriate. Results vary by panel type, usage patterns, and the severity of existing wear.
