I recently summarized a research review of the Sony PVM-2541 (OLED). The paper itself is open access. and can be found here
. My brief summary is here
While they didn't discuss burn in, the manual
Due to an OLED’s panel structure and characteristics of materials in its design, displaying static images for extended periods, or using the unit repeatedly in a high temperature/high humidity environments may cause image smearing, burn-in, areas of which brightness is permanently changed, lines, or a decrease in overall brightness. In particular, continued display of an image smaller than the monitor screen, such as in a different aspect ratio, may shorten the life of the unit.
Avoid displaying a still image for an extended period, or using the unit repeatedly in a high temperature/high humidity environment such an airtight room, or around
the outlet of an air conditioner.
To prevent any of the above issues, we recommend reducing brightness slightly, and to turn off the power whenever the unit is not in use.
and even on their top of the line OLED, the BVM E250, from the manual
Due to the characteristics of the material used in the OLED panel for its high-precision images, permanent burn-in may occur if still images are displayed in the same position on the screen continuously, or repeatedly over extended periods.
Images that may cause burn-in
• Masked images with aspect ratios other than 16:9
• Color bars or images that remain static for a long time
• Character or message displays that indicate settings or
the operating state
• On-screen displays such as center markers or area
To reduce the risk of burn-in
• Turn off the character and marker displays
Press the MENU button to turn off the character displays. To turn off the character or marker displays of the connected equipment, operate the connected equipment accordingly. For details, refer to the operation manual of the connected equipment.
• Turn off the power when not in use
Turn off the power if the viewfinder is not to be used for
a prolonged period of time.
This product has a built-in screen saver function to reduce burn-in. When an almost still image is displayed for morethan 10 minutes, the screen saver starts automatically and the brightness of the screen decreases.
