EL640.400-C2, -C3 and –CD3 Operations Manual (020-0355-00A) 3
Product Profile
The EL640.400–C2, –C3 and –CD3 displays are VGA compatible high-resolution
electroluminescent (TFEL) 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 two displays are mechanically
identical.
The EL640.400–C2, –C3 and –CD3 are timing compatible with Planar
EL640.400–CB series displays and signal compatible with VGA Feature
Connector supporting the 350 and 400 line standard VGA modes. They may be
driven at frame rates up to 80Hz.
The displays require +5 Vdc and +11…+30 Vdc power input and four to five
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
5. Blanking in VGA timing modes
EL Technology
A display consists 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 soldered lead frames. The result is a flat, compact, reliable and
rugged display device.

The EL640.400–CD3 display includes a light absorbing ICE ( Integrated
Contrast Enhancement) construction of the display glass. ICE background
significantly improves the luminance contrast of the display in bright
ambients. The ICE also removes the halo around the lit pixels in dark ambient
making the appearance of each pixel extremely crisp and clear.
In the EL640.400–C2, –C3 and –CD3 , 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.

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 with 100 Ω
series resistor.
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
For easy interfacing with VGA display controllers the video input signals are
VGA Feature Connector compatible. The display automatically determines the
mode of operation. Connector J2 containes two control inputs. LOWPWR input
is used to minimize the power consuption of the display and ENABLE input is
used to shut off the display when it is not accessed (screen saver function). If
the ENABLE or _LOWPWR functions are not in use and the power is connected
via J1, the connector J2 can be left disconnected.
Connector J3 containes input for external luminance control it can be left
disconnected if its function is not needed.

Display Features
Display Operation Modes
EL640.400–C2, –C3 and –CD3 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. Timing 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. Atolerance 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 is pin and timing compatible with MD640.400 Series displays
and the Normal mode of EL640.400–CB 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 (T3 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 the different timing modes as well as setup and hold timing on
page 12-15.

NOTES:
The top and right borders border values are used for image centering to the
display matrix.
In VGA modes 0+, 1+, 2+, 3+, 7 and 7+ the character box 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 stops scanning
and only the DC/DC converter remains functional. The power consumption
only appr. 2W. 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 removing jumper PS2/2 (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 removing jumper 3 of the pin
strip PS2.
Brightness Control
The brightness of the display can be adjusted (appr. between 10 and 100%) by
an external 50kΩlogarithmic potentiometer between the LUMPOT1 and
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.
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 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
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
Ωcould 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
The luminance contrast of the ICE version of the display EL640.400–CD3 is
sufficient for operation without any contrast enhancement. An anti-reflective
coating or protecting sheet with anti-reflective treatment is recommended.
For best overall performance of EL640.400–C2 and –C3 , 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 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.
