Display color degradation is a common issue affecting both OLED and LCD screens over time. The most effective prevention methods include implementing pixel shifting and screen savers for OLED panels to combat burn-in, where static images cause permanent discoloration. Regular color calibration using hardware calibrators ensures accurate color reproduction and compensates for gradual shifts. Controlling brightness levels to 50-70% significantly reduces phosphor degradation in LCDs and organic compound stress in OLEDs. Using anti-glare coatings prevents abrasive cleaning that damages anti-reflective layers. Environmental controls like maintaining 20-30°C operating temperatures and 40-60% humidity slow chemical degradation. For LCDs, exercising pixels through full-screen white displays weekly helps redistribute liquid crystals. Power management features like automatic sleep mode after inactivity prevent unnecessary usage. These practices collectively preserve color accuracy, contrast ratios, and overall display performance throughout the device's lifespan.
