Control basics
The EL panel has 512 transparent column electrodes crossing 256 row
electrodes in an X-Y fashion. Light is emitted when an AC voltage is applied at
a row-column intersection. The display operation is based on the symmetric,
line at a time data addressing scheme which is synchronized by the external
VS, HS, and VCLK input signals. The internal control signals and the high
voltage pulses for the column and row drivers are generated
internally by the
control electronics. All control signal
inputs are HCT compatible with pull-up
resistors.
Power Input
The required supply voltages for the display are +5 Vdc
(Vcc1) for the logic and
+11…+30 Vdc input (Vcc2) for the
integrated DC/DC converter. The high
voltages needed
for driving the display are generated by the DC/DC
converter
from the Vcc2 input voltage. The input voltages
can be connected either
through J1 or J2.
Signal Inputs
Connector J1 contains input for the video signals,
connector J2 contains two
control inputs and connector
J3 contains input for external luminance control.
The
signals on J2 and J3 that are not used can be left
disconnected.
Optional Grounding
In order to improve the EMC properties of the display
system, there is an
option for the customer to tie together
the signal ground of the display and
the chassis of the
user device. For this purpose the four corner mounting
nuts
are each connected to the signal ground with
10 nF / 50 V capacitors. When
using this option, please
be aware of the possible risk of lowered isolation
strength
of the device and possible generation ground loops.
