Video Signal Input
For trouble-free data transfer from data transmitter to display input connector,
a maximum cable length of 600 mm (24 in.) is recommended. In the case of
VGA Feature Connector use, proper signal buffering should be ensured. In
order to lower signal reflections, the connecting cable should be terminated
with a matching series resistor at each of the eleven outputs of the signal
source. Data input thresholds of the display are 74ACT CMOS compatible, and
data lines have 4.7 k
Ω
pull up resistors and 100
Ω
series resistors connected at
their inputs.
Avoiding Burn-in
As with any other light emitting display, luminance variation may be noticed if
fixed patterns are displayed on the screen for extended periods. It is prudent
to use a screen saver or image inversion to avoid burn-in.
Caution: Properly mounted, this display can withstand high shock loads as well as
severe vibration in aggressive environments. However, the glass panel used in this
display will break when subjected to bending stresses, high impact or excessive loads
To prevent injury in the event of glass breakage, a protective overlay should be used
on the viewer side of the display.
Cleaning Caution: Clean the display glass with mild, water based detergants only.
Apply the cleaner sparingly.
Warning: The product generates potentially dangerous voltages capable of causing
personal injury (high voltage pulses up to 230Vac). Do not touch the display
electronics during operation!
Automatic Overheat Protection: The display is provided with an overheating sensor
to protect the display in the case of temporary overheating. When the temperature in
the display rises over specified limits, the automatic circuitry limits the power
consumption of the display and prevents the temperature to rise critical. When using a
typical power consumption of 16W within the specified operating temperature range,
the overheat protection is not needed.
Electrostatic Caution: The Planar display uses CMOS and power MOS-FET devices.
These components are electrostatic sensitive. Unpack, assemble and examine this
assembly in a static-controlled area only. When shipping use packing materials
designed for protection of electrostatic-sensitive components.
