Product Profile
The EL640.480-A SB series 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 integrated DC/DC
converter, and their compact dimensions save space that can allow addition of
features or reduction in overall size. The displays are mechanically identical.
The display format of EL640.480-A SB series displays is VGA compatible (640
columns by 480 rows) with sixteen true shades of gray. The display supports
and automatically detects all standard VGA modes.
The displays require a single +12Vdc power source and five basic types of
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
EL Technology
The display consists of an electroluminescent glass panel and a mounted
circuit board with addressing 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 aluminium; the column
electrodes, in front, are transparent. The entire thin film device is deposited on
a single glass substrate. The glass panel is mounted with an elastic spacer to an
assembly support carrying the electronic circuit assembly board (ECA)
mounted on the support. The driver electronics is connected to the EL glass
panel with soldered lead frame interconnects. The result is a flat, compact,
reliable and rugged display device.

The EL640.480-AD4 SB 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.
The 640 column electrodes and 480 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 integrated DC/DC
converter.

Note: Two data parallel mode is selected when DCON '2-d' bridge is open. On default setting the
bridge is set and 4 bits wide data is input to D0...D3 and does NOT require D4...D7 to be
connected.

adjust the luminance of the display. If left disconnected,
the luminance is at the max level. See page 9 for details.

LUMPOT2
Control Basics
The EL panel is a matrix structure, with column and row electrodes arranged in
X-Y formation. Light is emitted when an AC voltage of sufficient amplitude is
applied at a row-column intersection. The display operation is based on the
symmetric, line at a time data addressing scheme. Input thresholds to the
display are 74ACT CMOS compatible (TTL thresholds).
Power Input
The only required supply voltage for the display is +12Vdc (Vcc2). All internal
high voltages are generated from Vcc2.

Programmable Features
Two data parallel input mode is selected when bridge DCON on the ECA is
open (see fig. 2). In default configuration the DCON bridge is set. See page 9
for more details.
The method of gray scale coding can be selected either with COLMAP control
input (J1/27) (see Signal Inputs on page 5) or with solderable bridge MAP on
the ECA (see fig. 2). If COLMAP is left disconnected, MAP brigde defines the
mode. If MAP is left open (default), colour mapping is selected. If MAP is
bridged, binary coding is the method. Note that if COLMAP control input is
used MAP has to be open. See page 8 for more details on colour mapping.
Notice: Only binary coding of input data can be used with Two Data Parallel
mode. See Gray Shades and Two Data Parallel Mode in page 9.
For compatibility to previous versions of A series displays the horizontal and
vertical positioning of the image can be adjusted with solderable bridges on
the ECA of the display. VERPOS0–VERPOS2 (MSB) are for vertical positioning
and HORPOS0–HORPOS3 (MSB) are for horizontal positioning (see Fig. 2). Both
settings form a binary number where a set bridge is a "0" and open bridge 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).
Notice: Due to the fact that picture positioning is not supported by Planar
multi-colour VGA displays and may not be supported by some future Planar
VGA displays, the use of this feature should be avoided.

Note: Absolute maximum ratings are those values beyond which damage to
the device may occur. The minimum and maximum specifications in this
Operations Manual should be met, without exception, to ensure the long-
term reliability of the display. Planar does not recommend operation of the
display outside these specifications.

Display Features
The EL640.480-A SB series displays are timing and pin compatible with the
feature connector on VGA display controller cards. Pins 1–26 on the feature
connector connect directly to corresponding pins on data input connector J1
of the display. Pins 27–34 may be left disconnected.
Video Data
Input signals D0, D1, D2, D3 (and D4, D5, D6, D7 in two data parallel mode)
contain the four bit serial video data to be displayed on the screen. Pixel
information is supplied from left to right and from top to bottom. The four
data bits can be interpreted as colour data or binary gray shade codes.
Gray Shades
The display is capable of displaying sixteen true levels of luminance. The four
bit video input data can either be mapped to colour coding or binary gray
shade coding. Colour coding is selected by pulling COLMAP control input
HIGH. A LOW state in COLMAP control input selects binary coding. See
'Programmable Features' in page3 for setting the coding if COLMAP input is
left disconnected.

For maximum text readability, the default text brightness level is mapped in
text modes 2+, 3+, 7 and 7+ to high intensity white (level 15). If colour coding
is selected levels 11 and 15 are changed. If binary coding is selected, levels 7
and 15 are changed respectively. Please find complete description of VGA
modes in page 11.
