Some luminance level between the ideal/target "on" and "off" levels?strayan wrote:Explain how burn in would be visible with white text on a black background. Burn in is a non issue.freyesm wrote:OLED display isn't a good idea.
It burn in and loses bright kinda fast, unless you are planning to show the information for just 5~10 seconds, then turn it off.
There are good reasons for this concern. Consulting the NHD-0220CW-AW3 datasheet:
The OSSC Pro is probably a device most people would like to keep using for some time – time until half-brightness for average 50% pixels on is specified as ~5.7 years "minimum". Most people presumably won't have their OSSC Pro switched on 24/7, which should increase that timespan; the display probably also degrades, more slowly, while switched off. The current input video status is probably what is displayed most of the time, which is relatively static – in the worst case (left on 24/7 with same pixels lit and a bit of misfortune), these pixels may reach half-brightness in ~2.9 years, based on that data.
I'm not worried about luminance degradation or burn-in if the Pro FW can switch the display off after some sensible amount of time without user input, as has been suggested. Interestingly, the yellow variant of the display has a lifetime rating of 80,000h (the datasheet of the NHD-C0216CZ-FSW-FBW-3V3, used by the OSSC Classic, doesn't include a lifetime rating).
