The flexible interconnects between the display glass and the ECA carry high
voltages and are very sensitive to touch. Handling and mounting of the display
should be done from the four corners of the assembly support only.
For trouble-free data transfer from data transmitter to display input connector,
a maximum cable length of 600 mm (24 in.) is recommended. In 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 appr.
100 series resistor at each of the five signal line outputs of the signal source.
As with any other light emitting display, luminance variations 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.
Electrostatic Caution: This Planar display uses CMOS and power MOS-FET
devices. These components are electrostatic sensitive. Unpack, assemble and
examine this assembly in a staticcontrolled area only. When shipping use
packing materials designed for protection of electrostatic-sensitive
components.
Warning: The product generates potentially dangerous voltages capable of
causing personal injury (high voltage pulses up to 195 Vac). Do not touch the
display electronics during operation!
