If a high level signal is continuously
displayed on the same area in the
HDR display, the protection
function activates wherein the
brightness of the bright part in the
display decreases to control the rise
of the surface temperature of the
OLED panel. When the level of the
bright part decreases or the change
of its position continues, the
protection function is deactivated.
However, it may take a while to
deactivate.
