Product Profile
The EL512.256–H series displays are rugged, high resolution
electroluminescent (EL) flat panel displays. They replace the bulky CRT in
control and instrument product designs. They feature an integrated DC/DC
converter, and their compact dimensions save space that can allow addition of
features or reduction in overall size. They are designed to work in extreme
environments and the crisp display is viewable at wide viewing angles both in
horizontal and vertical directions. Their ease of installation reduces system
integration costs.
The EL512.256–H is a 512 column by 256 row flat panel display with a 1:1 pixel
aspect ratio. The digital flat panel interface is designed to match the needs of
most systems. The displays may be driven at frame rates up to 75 Hz.
The EL512.256–H displays require +5 Vdc and +11…+30 Vdc power input and
four basic input signals to operate:
1. Video Data or pixel information
2. Video Clock, pixel clock, or dot clock
3. Horizontal Sync
4. Vertical Sync
EL Technology
Figure 1. EL Technology.
A display consists of an electroluminescent glass panel and a mounted circuit
board with control electronics. The EL glass panel is a solid-state device with a
thin film luminescent layer sandwiched between transparent dielectric layers
and a matrix of row and column electrodes. The row electrodes, in back, are
aluminium; the column electrodes, in front, are transparent. The entire thin
film device is deposited on a single glass substrate. The glass panel is mounted
to an electronic circuit assembly board (ECA) with an elastic spacer. The ECA is
connected to the EL glass panel with soldered lead frames. The result is a flat,
compact, reliable and rugged display device.

EL512.256-H Series Operations Manual (020-0354-00A)
In EL512.256–H series displays, the 512 column electrodes and 256 row
electrodes are arranged in an X-Y formation with the intersecting areas
performing as pixels. Voltage is applied to both the correct row electrode and
the correct column electrode to cause a lit pixel. Operating voltages required
are provided by an integral DC/DC converter.

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.

Note: Absolute maximum ratings are those values beyond which damage to
the device may occur. The minimum and maximum specifications in this
Operations Manual should be met, without exception, to ensure the longterm reliability of the display. Planar does not recommend operation of the
display outside these specifications.
Display Features
Video Data Input
Four input signals are needed for video input. VS signal marks the topmost
row, HS envelopes the pixels in one row and VCLK indicates the valid pixel
data. The visible pixels in a row are the last 512 pixels before the fall of the HS.
The topmost row displayed is the first HS HIGH time ending after the rising
edge of VS. If HS is running continuously, the rising edge of the VS can be
simultaneous to the previous falling or rising edge of the HS.
See details on the timing as well as setup and hold timing on pages 9 and 10.

EL512.256-H Series Operations Manual (020-0354-00A)
Two Bit Parallel Data
To reduce the input data frequency the video data can be input two bits per
clock cycle. The two data inputs are organized so that the data for the odd
columns, numbered from left to the right at the viewers side, is input at the
TVID (J1/ pin 7) and the data for the even columns at VID (J1/ pin 15). The two
bit parallel mode is selected by removing jumper 2 of the pin strip PS1.
Display Enable
The display can be totally shut off for screen save or power reduction by a LOW
sate in the ENABLE control input (J2/pin 6). When disabled, the display stops
scanning and only the DC/DC converter remains functional lowering the
power consumption to below 2 W. In normal operation the ENABLE input
should be pulled HIGH or left disconnected (internal pull-up).
Brightness Control
The brightness of the display can be adjusted (appr. between 40 and 100%) by
an external 50 k
LUMPOT 2 inputs (J3/pins 1 and 2). The control function is done by feeding a
small DC current signal via the external potentiometer from LUMPOT1 (+5V
reference voltage) to LUMPOT2. If the two inputs are left disconnected, the
brightness is at its maximum level.
Ω
logarithmic potentiometer between the LUMPOT1 and
Low Power Mode
The power consumption of the display is possible to be reduced typically to 4
W by using the low power mode. This mode is selected when _LOWPOW
control input (J2/5) is pulled low. In normal operation _LOWPOW should be
pulled HIGH or left disconnected. In low power mode the contrast and average
brightness of the display are slightly reduced.
Self Test
The operation of the display can be easily checked without any external
signals by the self test function.
Remove Jumper 1 in pinstrip PS1.
Connect power to the display.
All pixels of the display will be lit with the exception of the first half of the
topmost row.

Installation and Handling
The product should be mounted using the M3 insert nuts on the ECA. Beside
the four corner nuts it is recommended to use also the two center nuts in the
mounting, if the vibration or shock stress is severe.
Before touching the display, necessary precaution must be taken to prevent
application of static charges on the display from the operator or tools.
The display is made of glass material and should be handled with proper care.
Do not drop the display or allow hard objects to strike its surface.
NOTE: For trouble-free data transfer a maximum cable length of 300 mm (12
in.) from data transmitter to display input connector is recommended. If
longer cables up to 2m (80 in.) length are needed, a serial resistor of appr. 47
Ω could be placed at each of the four signal line outputs of the
transmitter in order to lower signal reflections.
Electrostatic Caution: Planar display use 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!

Optional Filter
For best overall optical performance of the display, a neutral gray circular
polarizing filter with anti-reflective coating or etch is the usual choice. This
filter will make the reflective electrodes of the display darker and will improve
the contrast ratio. The anti-reflective coating on the filter should face the user.

CAUTION: The ambient temperature of the display should not be allowed to
exceed the environmental specifications (see Table 7). In most applications,
an air gap of appr. 5 mm is recommended (see mechanical drawings). Some
applications may require, however, a larger air gap or cooling of the display
unit in the system. Note that this may slightly increase the total depth of the
design.
