Product Profile
The EL640.400–CB1/3 and –CD4 displays are VGA compatible high-resolution
electroluminescent (EL) flat panel displays.They replace the bulky CRT in
control and instrument product designs. They feature an intergrated DC/DC
converter, and their compact dimensions save space that can allow addition of
features or reduction in overall size. The three displays are mechanically
identical.
The displays are timing compatible with Planar EL640.400–C3/CD3 displays
and signal compatible with VGA Feature Connector supporting the 350 and
400 line VGA modes. They may be driven at frame rates up to 72Hz.
The displays require +5Vdc and +12 or +24Vdc 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 or Blanking
4. Vertical Sync
EL Technology
Planar EL displays consist of an electroluminescent glass panel and a mounted
circuit board with control electronics.
Figure 1. EL Technology.
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. 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 flexible interconnects. The result is a flat, compact, reliable
and rugged display device.

3 EL640.400-CB1/CB3 and –CD4 Operations Manual (020-0356-00A)
The EL640.400–CD4 display includes a dark ICE (Integrated Contrast
Enhancement) background in the display glass. ICE background significantly
improves the luminance contrast of the display in bright ambients. ICE also
removes the halo around the lit pixels in dark ambient making the appearance
of each pixel crisp and clear.
In Planar EL640.400–C displays, the 640 column electrodes and 400 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.

5 EL640.400-CB1/CB3 and –CD4 Operations Manual (020-0356-00A)
Control basics
The EL panel has 640 transparent column electrodes crossing 400 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.
Power Input
The required supply voltages for the display are +5 Vdc (Vcc1) for the logic and
either +12 Vdc (–CB1 and –CD4) or +24 Vdc (–CB3) (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.
Signal Inputs
For easy interfacing with VGA display controllers the data and control input
signals are VGA Feature Connector compatible. The display automatically
determines the mode of operation.
The control input J2 includes contacts for optional luminance control and
ENABLE signal to totally shut off the display when not in use (screen saver
function).

Mating Hirose DF1–4S–2.5 R 28 or eq.
Luminance Control
The displays feature luminance control capability for users to set the
brightness of the display to meet the ambient lightning. The control function
is achieved by drawing a 0…1 mA current from LUMPOT1 to ground
(LUMPOT2). The luminance is at maximum level when the inputs are open. The
voltage level of LUMPOT1 (J2/1) is appr. 5.1 Vdc when disconnected.
Self Test
The operation of the display can be easily checked using the SELFTST function.
Self test is performed when SELFTST jumper (PS1/1) is set or no data input is
present. During self test all pixels are lit except the left-most half of the
topmost row of the display.

7 EL640.400-CB1/CB3 and –CD4 Operations Manual (020-0356-00A)
Display Features
Display Operation Modes
The displays have two input timing modes. VGA Mode supports standard 200,
350 and 400 row VGA modes and Normal Mode is similar to Normal Mode in
most Planar displays. The operation mode is determined from combination of
the polarities of the VS and HS pulses and the _BLANK signal at the rising edge
of the VS pulse and the polarities of VS and HS pulses at the rising edge of the
_BLANK pulse.
In VGA modes, the number of columns is determined by the number of VCLK
pulses during a HS pulse. A tolerance of ±1 pulse is accepted.
VGA Modes: The display data and control input is compatible with feature
connector signals from VGA board. The display supports VGA modes 0, 1, 2, 3,
0*, 1*, 2*, 3*, 0+, 1+, 2+, 3+, 4, 5, 6, 7, 7+, D, E, F, 10 and 13. It notifies the
polarity of the HS and VS at the rising edge of BLANK and determines the
number of rows in the mode. Note that in VGA modes 0, 1, 0*, 1*, 0+, 1+, 4,
5, D and 13, where the software uses 320 or 360 columns, the size of
borders varies from one VGA- controller to another. Therefore the image
may not be centered properly using those modes.
The image is centred automatically, and in text modes with 720 pixels
horizontally, every ninth pixel is omitted for compatibility. The non-displayed
pixel is in the space region of the character matrix, and therefore no
information is lost. The borders are normally eliminated because of the
centering. The upper and lower borders are however displayed in the modes
using 350 rows due to extra rows not needed for the picture.
The 480 row VGA modes are not supported. Even if the display does not scan
in these modes (11, 12), it continues to operate with no failures when a
supported mode is detected.
Normal Mode: This mode is pin and timing compatible with MD640.400 Series
displays and the Normal mode of EL640.400–C3/CD3 series displays. In this
mode only four input signals are needed: video data (VID), video clock (VCLK),
horizontal synchronizing (HS) and vertical synchronizing (VS). _BLANK is not in
use and should be pulled high or left disconnected.
In Normal mode the last 640 pixels before the fall of the HS are displayed. The
topmost row displayed is the first HS HIGH time ending after HS Hold from VS
time (T4 in Normal Mode) from 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 setup and hold timing as well as
Normal Mode timing on page 14.

NOTES:
In VGA modes 0+, 1+, 2+, 3+, 7 and 7+ the character box width is narrowed to
8 pixels by omitting the data of every 9th pixel. In VGA modes 0, 1, 0*, 0+, 1+,
4, 5, D and 13, where the software uses 320 or 360 columns, the size of
borders may vary from one VGA-controller card to another. The potentially
needed picture adjustments may be done by programming the registers of
the VGA controller chip.
Double Scan is a VGA card feature.
VGA modes 11 and 12 with 480 rows are not supported.
Display Enable
The display can be totally shut off for screen save or power reduction by a LOW
sate in the ENABLE control input. When disabled, the display is totally dark and
only the DC/DC converter remains functional consuming only appr. 2 W. In
normal operation, the ENABLE input should be pulled HIGH or left
disconnected (internal pull-up).
200 Rows Mode
200 Input data rows may be displayed using 400 rows by automatically
doubling every data row to two consecutive display rows. This function is

selected by installing jumper PS1/2 (F2040). The _BLANK input must also be in
LOW state. For more information of this mode contact Planar.
Two Bit Parallel Data
To reduce the input data frequency in NORMAL mode 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 installing jumper 3 of the pin strip
PS1.
Brightness Control
The brightness of the display can be adjusted (appr. between 10 and 100%) by
an external 50 logarithmic potentiometer between the LUMPOT1 and
LUMPOT 2 inputs (J2/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.
Self Test
The operation of the display can be easily checked without any external
signals by the self test function.
Insert Jumper 1 in pinstrip PS2.
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
Mounting
Mounting of the display should be done using the M3 insert nuts on the four
corners of the plastic assembly support or the four holes in the FRA frames.
Note that because all four mounting points are internally connected to signal
ground care should be taken to avoid grounding loops.
Handling
Before handling 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.

EL640.400-CB1/CB3 and –CD4 Operations Manual (020-0356-00A)
10
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.
Cable Length
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.
Avoiding Burn-in
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!

Filter
The luminance contrast of the ICE display CD4 is sufficient for operation
without contrast enhancement filter. For best overall performance of the
monochrome CB1 and CB3 displays in high or low ambient light levels, a
neutral gray circular polarizing filter with anti-reflective coating or etch is
recommended. This filter will make the background of the display darker and
will improve the luminance 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 10). 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.
