40 Special instructions for TV sets with
OLED technology
"OLED twin R" televisions are equipped with OLED screen techno-
logy.
The source of the OLED technology's advantages in picture quality is
the fact that OLED at subpixel level is an individually controllable
self-luminous technology. The more differentiated screen control is,
the more negative the effect of motionless pictures or sections of
pictures upon degradation is. Consequently, these should, if possi-
ble, either be avoided or be subject to a time limit.
In normal TV operation, the device has various internal mechanisms
which prevent damage to the image quality. However, the prescri-
bed automatic calibration cycles must be performed in standby
mode for this purpose.
To ensure that your OLED TV always delivers a first-class image, you
should pay attention to the following points:
• Avoid still images over longer time periods.
• Avoid picture content with a still image character (e.g. a static
outer frame containing a moving image) over long periods.
• Avoid using presentation mode.
• After four hours of operation, the device starts an "RS compensation
cycle" as soon as the set is switched to standby mode . “Calibration”
will appear in the text display. The TV screen will remain dark. This
process can take a few minutes and removes residual stress in the
OLED panel control.
If this process is prevented or interrupted, the following will appear at a
later time:
After four hours of use, your Metz OLED device will be calibrated for opti-
mal image display at the earliest opportunity. For this to happen, the de-
vice must be in standby mode. Because the device was last switched off
with the power switch, it was not possible to run the calibration.
Please switch the device to standby with the remote control. The display
will then be calibrated.
Once only the red LED is illuminated, the device can be turned off with the
power switch. If you do not switch off to standby mode, the calibration
will be performed automatically at the next start.
If this process is prevented or interrupted, mandatory calibration will
occur at a later time, which cannot be cancelled.
The following will appear on the screen.
You did not use standby mode the last time the device was switched off.
As a result, the device is now being automatically calibrated.
This operation cannot be interrupted with the remote control.
Please do not switch off the device with the power switch.
Once only the red LED is illuminated, can the TV can be returned to ope-
ration.
• After around 600 hours of operation, JB compensation will be
performed as soon as the device is put in standby mode. “Calibra-
tion” will appear in the text display. The TV screen will remain dark.
During the last few minutes of JB compensation, a thin white line will
be visible, travelling from top to bottom. This involves irregularly
degraded subpixels being recorded and compensated for.
This process lasts about 70 minutes and removes residual voltage in
the OLED panel control.
• First switch off the TV set using the power switch when only the red
standby LED is illuminated.
