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
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.
