Design and function
This chapter introduces the systems and explains some of their characteristics.
4.1
Display of choice
The displays are latest generation FullHD LCD displays with full matrix LED backlight.
The displays utilize a state-of-the-art IPS (in plane switching) LCD panel technology. This allows them being used
for an extended period of time without image sticking artifacts.
The displays are illuminated by a full matrix LED backlight: the white LEDs are positioned in an array behind the
screen.
The display features the following interfaces:
OPS
OPS
OPS Open pluggable specification channel with HDCP 1.4
DVI 1, DVI 2
DVI single link input with HDCP 1.4, up to 165 MHz)
HDMI
HDMI 1.4a with HDCP 1.4, up to 300 MHz
DP
DisplayPort input with HDCP 1.3, up to 300MHz
DP
DisplayPort output with HDCP 1.4
S/PDIF
Audio output interface according Sony/Philips Digital Interface specification
LAN 1, LAN 2
1 GB Ethernet input, video streaming supported.
USB
USB interface USB 2.0
All inputs (OPS, DVI 1, DVI 2, HDMI, DisplayPort) have a loop-through connection to DisplayPort out (loop-through
connection is established as soon as the input is the active input).
The state-of-the-art displays deliver crisp, clear images detailed to perfection and can be used in different pro-
fessional applications.
The displays have a Web interface and can be addressed using any web browser in the subnet.
The display can be controlled via LAN using the BCM client application (Barco Wall Control Manager) or via API.
4.2
Cooling concept
The display features LED backlight.
LEDs like all semiconductors are quite sensitive to thermal stress and require a stable temperature for optimum
operation. Reliable heat dissipation is mandatory for a long lifetime.
As a rule of thumb lowering the temperature by 10°C will double product reliability.
Reliable heat dissipation is also mandatory stable intensity!
A temperature change of 10°C will shift the dominant wavelength of the emitted light of an LED up to 4nm (in-
creasing temperature leads to shorter wavelengths).
Therfore the display has been provided with two cooling fans. The cooling of the electronics and the cooling of
the power supply is separated. This ensures a decoupling of the power section with the higher heat dissipation
versus the low power electronics for the logical controller.
Temperature is measured by sensors and continuously monitored by Barco Wall Control Manager which controls
the ultra low noise fans for optimal cooling.
