I've got a Thinkpad 770 running OS/2 Warp 4 and I've noticed recently
what looks to be minor burn in of the LCD. I thought these displays
were immune from burn in, but I'm clearly seeing the ghostly images of
my default icon items in the Warp Center tray as I change trays.
I also can see the Warp Center image if I hide the warp center. It
looks just as it might if you left it burning into a CRT display.
I'm only seeing this ghost image with Warp Center which inhabits the
top of my screen. The regular Control Center is at the bottom my
screen and I don't see ghost images of it if I hide the Center. This
is most likely due to the settings I have chosen for both; Warp Center
can not be covered by other windows while the Control Center can.
Hence there is more "screen time" for the warp center.
I did a high res screen capture of the display and did not see the
ghost images, which fits in with it being display burn in and not a
video issue. If this is screen burn in can someone provide a technical
explanation? I understand how burn in occurs on CRTs, but honestly
thought LCDs were immune to this problem.
Thanks.
Jeff
