pi-function helps eliminate image retention
Image retention (image retention or burn-in) occurs when traces of previous static images remain on the screen. This is a common issue with modern displays.
pi-function is a modern browser utility that uses dynamic patterns: white noise and alternating colors. Regular use helps “discharge” pixels and minimize burn-in effects.
How it works on different panel types
| Panel Type | Problem Manifestation | How pi-function helps |
|---|---|---|
| LCD (TN, IPS, VA) | Temporary sticking due to charge in crystals | Rapid pattern switching accelerates recovery |
| OLED / QD-OLED | Permanent burn-in of organic light-emitting diodes | Uniform noise reduces uneven subpixel wear |
| Old CRT | Long phosphor persistence | Intense noise quickly erases remnants |
It is recommended to run the cleaning 1–2 times a week for 10–20 minutes in fullscreen mode. The “Multicolor White Noise” mode is especially effective for OLED monitors.
Screen Cleaning Tool
Launch one of the modes. The patterns will evenly stress the pixels and reduce image retention.
Additional features in development:
☺ — More cleaning modes: “Strict RGB Noise”, “Glare”, “Flashes”, “Flicker”, “MIX”, etc.
☺ — Additional fill colors from the CMYK color model, plus the ability to add up to five custom preset colors.
☺ — Floating window mode for cleaning a specific part of the screen while working.
☺ — Ability to combine modes in any order with custom processing time for each.
☺ — Additional screen processing using pre-recorded videos with 8K, 4K, 2K, FHD, HD quality selection.
