1Product profile
The EL640.400-C2, -C3 and -CD3 displays are VGA-compatible high-resolution Thin Film
Electroluminescent (TFEL) 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 allows 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 the EL640.400–CB series
displays and signal-compatible with a VGA feature connector supporting the 350 and 400 line
standard VGA modes. They may be driven at frame rates up to 80 Hz.
The displays require +5 VDC and +11 VDC …+30 VDC power input and four to five basic input
signals to operate:
Video Data or pixel information
Video Clock, pixel clock, or dot clock
Horizontal Sync
Vertical Sync
Blanking in VGA timing modes
2TFEL technology
A display consists of an electroluminescent glass panel and a mounted circuit board with
control electronics.
Figure 1. TFEL technology
The TFEL 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 TFEL 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 ICEBrite™ (Integral Contrast
Enhancement) construction of the display glass. The ICEBrite background significantly
improves the luminance contrast of the display in bright ambient. The ICEBrite 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.

3.3 Control basics
The TFEL 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 a 100 Ωseries resistor.
3.4 Power input
The required supply voltages for the display are +5 VDC (Vcc1) for the logic and +11 VDC …+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.

3.6 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. The
connector J2 contains two control inputs: the LOWPWR input is used to minimize the power
consumption of the display and the ENABLE input is used to shut off the display when it is not
accessed (screensaver 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.
The connector J3 contains input for external luminance control. It can be left disconnected if
its function is not needed.
3.7 Jumper description
PS1
The horizontal and vertical positioning of the image can be adjusted with jumpers on
pin strip PS1. VERPOS0…VERPOS2 (MSB) are for vertical positioning and
HORPOS0…HORPOS3 (MSB) are for horizontal positioning. Both settings form a binary
number where a set jumper is a “0” and open jumper a “1”. The adjustment range for
VERPOS is 0 to 7 upwards (default 000 for no shift) and HORPOS 7 right (0000) to 8
left (1111) (default 0111 for no shift).

4Display features
4.1 Display operation modes
The 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 Beneq displays. Timing mode is determined from a 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 centered 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 the MD640.400 Series displays and the
normal mode of the 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.

4.3 Display enable
The display can be totally shut off for screen saving 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 is only approximately 2W. In normal
operation, the ENABLE input should be pulled HIGH or left disconnected (internal pull-up).
4.4 200 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 the jumper PS2/2
(F2040). The _BLANK input must also be in LOW state. For more information of this mode,
contact Beneq.
4.5 Two-bits-parallel data
To reduce the input data frequency in the 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 viewer side, is input at the TVID (J1/ pin 7) and the
data for the even columns at VID (J1/ pin 15). The two-bits-parallel mode is selected by
removing the jumper 3 of the pin strip PS2.
4.6 Brightness control
The brightness of the display can be adjusted (approximately between 10% and 100%) by an
external 50 kΩlogarithmic 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 (+5 V reference voltage) to LUMPOT2. If the two
inputs are left disconnected, the brightness is at its maximum level.
4.7 Self-test
The operation of the display can be easily checked without any external signals using the
self-test function.
Remove the jumper 1 in the pin stripe PS2.
Connect power to the display.
All the pixels of the display will be lit with the exception of the first half of the topmost row.

5Installation 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 approximately 47 could be placed at each of the four
signal line outputs of the transmitter in order to lower signal reflections.
ELECTROSTATIC CAUTION: Beneq display use CMOS and power MOS-FET devices. These
components are electrostatic-sensitive. Unpack, assemble and examine this assembly in a
static-controlled 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!

6.5.2 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 a protecting sheet
with anti-reflective treatment is recommended. For the best overall performance of the
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 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
approximately 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.
