1EL640.480-AF1 VGA display
This manual describes Lumineq
®
Displays ICEBrite™ EL640.480 AF1 series of displays. This
6.4" diagonal VGA product offers dramatic visual improvements over passive LCDs.
Utilizing Lumineq proprietary ICEBrite (Integral Contrast and Brightness Enhancement)
technology, this display excels in ambient light environments ranging from dark to nearly
sunlight bright. This technology achieves very high contrast and exceptionally clear images.
The display utilizes an 8 bit FPD type interface compatible with most passive LCD video
controller chips, making it easy to integrate and to replace existing LCD displays.
Through simple design and advanced manufacturing technologies, Lumineq’s new VGA
display family brings the visual performance and image quality of thin film
electroluminescence (TFEL) into cost sensitive applications that have up to now been limited
by the performance of LCD displays.
1.1 Features and benefits
•Excellent visual performance
High brightness and contrast
Wide viewing angle
•Significant reduction in cost over previous TFEL technology
•Reliable, long operating life
•Extremely rugged and durable
•Low EMI emissions
•Rapid display response
•Low power design
1.2 Opti ns
Conformal coating and extended temperature options are available for this display.
The conformal coating option adds a protective layer to the display for applications in which
the display may be subjected to high humidity, dust, or salt mist.
The extended temperature (ET) option provides a 40 °C to +85 °C operating temperature
range, analog dimming capability, and a locking input connector.

2Installati n and handling
The mechanical package consists of the display panel and electronic circuit board adhesively
bonded together and mounted in a plastic bezel. The bezel supplies the mounting ears and
protects otherwise exposed leads. The display is made of glass material and must be handled
with care.
CAUTION: The display uses CMOS and power MOSFET 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.
Do not drop, bend or flex the display. Do not allow objects to strike the surface of the
display.
2.1 M unting
The AF1 display is designed to facilitate the mounting of optical treatments and touch screens
on the viewing side of the display. To this end, the glass extends in front of the mounting
bezel by approximately 0.5 mm (0.02") It is imperative that any mounting scheme apply
uniform pressure across the glass at all times. Pressure applied only to the corners or edge of
the glass is likely to cause breakage.
Mounting should be done using the mounting ears only. Use either metric M3 screws
tightened to 350 Ncm maximum, or unified #4 screws tightened to 4.7 in/lb maximum.
CAUTION: Properly mounted, this display can withstand high shock loads and severe
vibration in aggressive environments. However, the glass panel used in this display will break
when subjected to bending stresses, high impact, or excessive loads.
CAUTION: To prevent injury in the event of a glass breakage, a protective overlay should be
used on the viewer side of the display.
WARNING: These products generate voltages capable of causing personal injury (high
voltage up to 230 V
AC
). Do not touch the display electronics during operation.
2.2 Cleaning
As with any glass or coated surface, care should be taken to minimize scratching. Clean the
display glass with mild, water based detergents only. Apply the cleaner sparingly to a soft
cloth, and then wipe the display. Disposable cleaning cloths are recommended to minimize
the risk of inadvertently scratching the display with particles embedded in a re used cloth.
The TAB (tape automated bonding) leads between the electronics and the display glass are
very sensitive to handling. When cleaning the edges of the display glass, special care should
be taken not to damage the leads.

2.3 Cable length
Do not exceed the maximum cable length of 600 mm (24 in.). Longer cables may cause data
transfer problems between the data transmitted and the display input connector. Excessive
cable lengths can pick up unwanted EMI. There are third party products, which allow this
maximum cable length to be exceeded. Contact Beneq Application Engineering for more
information.
2.4 Av iding burn-in
As with other light emitting displays, displaying fixed patterns on the screen can causes
burn in where luminance variations can be noticed. Use a screensaver or image inversion to
avoid causing burn in on the display.
3Specificati ns
3.1 C ntr l basics
The EL panel is a matrix structure with column and row electrodes arranged in an 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. Required operating voltages are provided by an integrated DC/DC
converter.
Unless otherwise specified, performance characteristics are guaranteed when measured at 25
°C.
3.2 P wer
The supply voltages are shown in Table 1. All internal high voltages are generated from the
display supply voltage (V
H
). The logic supply voltage (V
L
) should be present whenever video
input signals or V
H
is applied. The minimum and maximum specifications in this manual
should be met, without exception, to ensure the long term reliability of the display. Beneq
does not recommend operation of the display outside these specifications.

CAUTION: Absolute maximum ratings are those values beyond which damage to the device
may occur.

CAUTION: There is no overcurrent protection on either the V

inputs to protect against
catastrophic faults. Beneq recommends the use of a series fuse on the 12 volt supply. A
general guideline is to rate the fuse at 1.8 to 2 times the display maximum current rating.

3.4 Interfacing
This dual scan, LCD type video interface provides a low cost, flexible method for controlling
display brightness and power consumption. Many off the shelf chipsets are available for
interfacing to flat panel displays. If your application does not require chip level integration,
there are many vendors that can supply board level solutions for serial control, PC104, ISA,
and many other interfaces.
3.4.1 Vide input signals
The end of the top line of a frame is marked by S, scan start up signal, as shown in Figure 2.
The end of each row of data is marked by CP1 as shown in Figure 2 and Figure 3.
Input signals UD0 through UD3 contain the video data for the upper screen and signals LD0
through LD3 contain the data for the lower screen. For example, four pixels (UD3—UD0) are
sent to row 1 at the same time as four pixels (LD0—LD3) are sent to row 241. This results in
eight pixels sent on each cycle of video clock CP2. Pixel information is supplied from left to
right and from top to bottom. Video data for one row is latched on the fall of CP1 (Figure 4).

Figure 4. Data f rmat
3.5 Self-test
The display incorporates a self test mode composed of a 1 x 2 checkerboard pattern that
inverts and alternates with an all pixels on pattern. The self test mode is entered by applying
power to the display with the S signal static. The display remains in this mode until two (2)
low to high transitions of the S signal are detected. The display then enters and remains in
normal (user video driven) operation as long as power is applied. To enter self test mode
again, the display must be reset by cycling the V
H
power input.
