and vivid colour management. High flat panel screen
resolutions and refresh rates are supported with formats
including 1366 × 768 @ 100Hz/120Hz and 1920 × 1080 @
100Hz/120Hz. The combination of Ethernet, CI+ and H.264
supports new TV experiences with IPTV and VOD. On top of
that, optional support is available for 2D dimming in
combination with LED backlights for optimum contrast and
power savings up to 50%.

Ambilight
Sets in the xxPFL7606D/xx range are equipped with Ambilight.
For the implementation of Ambilight, refer to
Figure 7-8
.
Figure 7-8 Ambilight configuration
The Ambilight implementation consists of 2 separate units in
the set, where the Ambilight module located on the right (seen
from the back of the set) acts as a Master and the module on
the left acts as a Slave.
The NVM is located on the Master Ambilight module. This
module communicates via the SPI communication protocol
with the CPLD located on the SSB whereas the Slave Ambilight
module communicates via the PWM communication protocol
with the Master Ambilight module.
The supply voltage of the modules is +24 V.
Refer to
Figure 7-9
and
Figure 7-10
for the Ambilight board
implementation.
