I was playing ZTris on my TI-84 Plus K-0109N yesterday, I paused the game to do something else and forgot that it is still displaying the pausing screen. When I woke up today, I suddenly recalled that the calculator is still on so I exited the game and returned to homescreen, noticing a darker-than-normal vertical strip on the left side of screen. I tried adjusting the contrast, putting it aside without batteries for hours, but these does not help much. I heard that OLED screen can "easily" get images burned-in, but I never expected such thing to happen on my calculator, which uses a monochrome LCD.
My questions are:
Here is a photo showing the burned-in strip on homescreen:
EDIT: The "burn-in image" have nearly disappeared after days of chilling, it's hardly visible now.
My questions are:
- Will it disappear over time? Is there anything I can do to make it better?
- Will it have any bad influence on LCD response time/contrast/etc. ?
