EL4737HB and EL4737HB-ICE
320 x 128 Pixel Electroluminescent Display
Product Profile
The EL4737HB and the EL4737HB-ICE displays are
low power, rugged, high-resolution electroluminescent
(TFEL) flat panel displays. They replace the LCD or bulky
CRT in instrument product designs. Their compact
dimensions save space that can allow addition of features
or reductions in overall size. They are designed to
function in extreme environments, and the crisp displays
are viewable under most lighting conditions at wide
viewing angles. Their ease of installation reduces system
integration costs.
The EL4737HB and the EL4737HB-ICE are 320
column by 128 row flat panel displays. The pixel aspect
ratio is 1:1. The CRT-type interface is TTL-compatible
and is designed to match the needs of most systems.
These displays also have an interface mode for hardware
compatibility with the Hitachi HD61830B or equivalent
LCD controller. These displays may be driven at frame
rates up to 120 Hz for applications requiring extra
brightness.
The displays require DC power and four basic signals
to operate:
1. Video Data or pixel information (VID)
2. Video Clock, pixel clock, or dot clock (VCLK)
3. Horizontal Sync (HS)
4. Vertical Sync (VS)
EL Technology
A display consists of an electroluminescent glass
panel and a mounted circuit board with control elec-
tronics.

Operations Manual
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 aluminum;
the column electrodes, in front, are transparent. The
entire thin film device is deposited on a single glass
substrate. A circuit board is connected to the back of the
glass substrate. Components are mounted on this circuit
board within the same area as the electroluminescent
viewing area on the glass panel. The circuit board is
connected to the glass with metal-on-elastomer
interconnect technology. The result is a flat, compact,
reliable and rugged display device.
The EL4737HB-ICE display includes a light absorbing
Integral Contrast Enhancement (ICETM) construction of
the display glass. ICETM background
significantly improves the luminance
contrast of the display in bright ambients,
and makes the display easier to read by
increasing the crispness of the pixels.
The 320 column electrodes and 128
row electrodes are arranged in an X-Y
formation with the intersecting areas
performing as pixels. Voltage is applied
V(t)
to both the correct row electrode and
the correct column electrode to cause a
lit pixel. Special operating voltages
required are provided by a DC/DC
converter.

3, 4 Voltage VL +5V optional input, see page 4.
5 Scan Mode SMODE Mode 1 (Standard timing) is selected by taking pin 5 high (or left unconnected). Mode 2 (LCD
timing) is selected by pulling pin 5 low. This signal passes directly from the user to the display
via the DC/DC converter. It is not buffered or terminated within the DC/DC converter.
6 not connected
7, 8, 10
12, 14, 16 Ground GND Signal return.
9 Vertical Sync VS A new frame is initiated by the high state of VS. To properly sync the EL display, VS must be high
at the end of line 1. This signal passes directly from the user to the display via the DC/DC
converter. It is not buffered or terminated within the DC/DC converter.
11 Horizontal Sync HS Mode 1: HS high time brackets the active pixel data for a horizontal scan line. Mode 2: HS marks
the last pixel of a horizontal scan line. HS high time should be less than 1 tVCLK. In either mode,
HS period must be an even multiple of 4 tVCLK. The last 320 pixels prior to the falling edge
of HS will be visible on the display. This signal passes directly from the video source to the display
via the DC/DC converter. It is not buffered or terminated within the DC/DC converter.
13 Video Clock VCLK VCLK provides the necessary signal to latch in the information present on VID. The VID and HS
signals are referenced to VCLK, which must continuously run. Data latching occurs on the falling
edge of VCLK. This signal passes directly from the video source to the display via the DC/DC
converter. It is not buffered or terminated within the DC/DC converter.
15 Video Data VID VID contains the serial video data to be displayed. A logic high corresponds to a lit pixel. Pixel
information on VID is supplied from left to right and from top to bottom; the first bit of data on
VID at the beginning of a frameis displayed as the pixel at the upper left corner of the display.
Bit number 320 is at the upper right corner. Bit number 321 is directly beneath pixel number
1 and so on. This signal passes directly from the video source to the display via the DC/DC
converter. It is not buffered or terminated within the DC/DC converter.

DC/DC Converter Calibration - PS512-1
The DC/DC converter cannot be tested separately. It
requires an active low enable signal from the display to
activate the high voltage section. The display provides this
signal after detecting the presence of video signals at its
input.
The DC/DC converter has been properly calibrated at
the factory to the EL display by means of a voltage output
adjustment. The converter should not need adjustment in
the field. If the DC/DC converter and display become
separated the following procedure can be used to set the
converter to the proper voltage:
1. Ensure power to the DC/DC converter is off.
2. Turn trimpot on the DC/DC converter fully
counterclockwise (ccw).
3. Connect the DC/DC converter to the display using
the flat cable.
J1 Jumper Function
EXT = +5V (VL) supplied by customer from an
external source.
INT = +5V (VL) generated from VH within the
DC/DC converter. Shipped set for INT from
factory.
4. Apply a full on video pattern to the display (full white
field). At the factory, calibration is done with all pixels on.
5. Set the DVM to measure a 250VDC voltage.
6. Connect the positive lead of the DVM to HV2 test
point. Connect the ground lead of the DVM to GND test
point on the DC/DC converter.
7. Apply power to the DC/DC converter.
8. Note the voltage statement is
on the display. A sample is shown
at right:
9. Adjust trimpot R20 on the DC/DC converter
clockwise (cw) until the voltage reading of the DVM is equal
to the V (ALL ON) voltage ±1V, as specified on the display.
Do NOT exceed 235V. Do NOT adjust R19.
10. Calibration is complete.

The Definition of Quality ®
Description of Warranty
This description is not the full warranty, and should
not be construed as a substitute for the full warranty. A
copy of the full warranty is available upon request.
Planar warrants that the goods it sells will be free of
defects in materials and workmanship, and that these
goods will substantially conform to the specifications
furnished by Planar, and to any drawings or specifica-
tions furnished to the Seller by the Buyer if approved by
the Seller. This warranty is effective only if Planar receives
notice of such defect or nonconformance during the
period of warranty, which begins the day of delivery.
The goods Planar sells are warranted for a period of
one year unless otherwise agreed to by Planar and the
Buyer. The Buyer must return the defective or non-
conforming goods, upon request, to Planar not later
than 30 days after Planars receipt of notice of the
alleged defect or non-compliance. Buyer shall prepay
transportation charges, and Planar shall pay for return
of the goods to the Buyer. No goods are to be returned
to Planar without prior written permission.
Easy to Use
There are many options available which make Planar
flat panel displays easy to use, easy to interface, and
easy to package. Call Planar for complete information.

egon and Espoo, Finland with a world-wide sales

tion number, please contact Planar Systems, Inc., or

The warranty does not apply in cases of improper or
inadequate maintenance by the Buyer, unauthorized
modification of the goods, operation of the goods
outside their environmental specifications, neglect or
abuse of the goods, or modification or integration with
other goods not covered by a Planar warranty when such
