EL480.240-PR2 Display
The EL480.240-PR2 thin film electroluminescent (EL) display is a low
cost, high performance alternative to industry-standard quarter-VGA
LCDs. The EL480.240-PR2 utilizes Planar’s proprietary Integral Contrast
and Brightness Enhancement (ICEBrite™) technology to achieve
unparalleled image quality without the use of expensive filters. This
small graphics display excels in a wide range of ambient lighting
environments while effectively eliminating the blooming common to
other high-bright displays.
The display consists of an EL glass panel and control electronics
assembled into a space-saving, rugged package for easy mounting.
The EL480.240-PR2 is easily interfaced using standard 4-bit LCD control
signals. Each of the 115,200 pixels has an aspect ratio of 1:1 (V:H) and is
individually addressable to clearly display high information content
graphics and text.
Features and Benefits
• Excellent visual performance:
High brightness and contrast
Wide viewing angle >160°
• Rapid display response <1 ms
• Space efficient mechanical package
• Low EMI emissions
• Extremely rugged and durable
• Reliable, long operating life with > 100,000 MTBF
• 4-bit LCD-type interface

Installation and Handling
Do not drop, bend, or flex the display. Do not allow objects to strike the
surface of the display.
CAUTION: The display uses 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.
CAUTION: To prevent injury in the event of glass breakage, the use of an
impact resistant shield or a protective overlay should be used on the viewer
side of the display.
Mounting EL Displays
Properly mounted, EL displays can withstand high shock loads as well as
severe vibration found in demanding applications. However the glass panel
used in an EL display will break if subjected to bending stresses, high impact,
or excessive loads.
Stresses are often introduced when a display is mounted into a product.
Ideally, the mounting tabs of the display should be the only point of contact
with the system. Use a spacer or boss for support; failure to do so will bend the
display and cause the glass to break. The instrument enclosure or frame should
not flex or distort in such a way that during use the bending loads might be
transferred to the display. Mounting surfaces should be flat to within ±0.6 mm
(±0.25"). Use all the mounting holes provided. Failure to do so will impair the
shock and vibration resistance of the final installation.
The EL480.240-PR2 is a tab mounted display. Use appropriate length standoffs
to assure that screws through the mounting tabs do not introduce bending
stresses into the display. Do not deflect the ECB out of its normal plane. The
EL480.240-PR2 mounting tabs were designed for a 3 mm screw.
WARNING: These products generate voltages capable of causing personal
injury (high voltage up to 230V
ac
). Do not touch the display electronics
during operation.

Cable Length
A maximum cable length of 600 mm (24 in.) is recommended. 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 Planar Application Engineering for more information.
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, 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.
Avoiding Burn-In
As with other light emitting displays, displaying fixed patterns on the screen
can cause burn-in, where luminance variations can be noticed. Use a screen
saver or image inversion to avoid causing burn-in on the display.

Specifications
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.
Power
This display requires both 12V and 5V in addition to video signals for proper
operation. The display is designed to accept simultaneous application of V
L
, V
H
,
and the input logic signals. If these signals are not simultaneous, they must
meet the sequential timing shown in Figure 1 below.
Figure 1. Data/Power Connector
The supply voltages are shown in Table 1. All internal high voltages are
generated from the display supply voltage (VH). The logic supply voltage (VL)
should be present whenever video input signals or VH is applied. The
minimum and maximum specifications in this manual should be met, without
exception, to ensure the long-term reliability of the display.
Performance characteristics are guaranteed when measured at 25
° C with rated
input voltage unless otherwise specified. Planar does not recommend
operation of the display outside these specifications.

Interface Information
Planar EL Small Graphics Displays (SGD) incorporate an interface that is similar
to many LCD interfaces. This interface is supported by a variety of off-the shelf
chip sets which take care of all display control functionality, freeing the system
processor for other tasks. Designers select the chip set that best suits their
particular architecture and price point. This 4-bit LCD-type video interface
provides a low cost, flexible method for controlling display brightness and
power consumption.
Video Input Signals
The end of the top line of a frame is marked by VS, vertical sync signal as
shown in Figure 2. The end of each row of data is marked by HS.
The VS signal may be independently set to a CMOS low level at any time for
longer than one frame period. During the time of VS inactivity the display is
blank. Halting VS results in a standby condition to minimize power usage.
Figure 2. Video Input Timing Diagram.
Timing is compatible with LCD graphics controllers such as the SMOS display
controller.

Self-Test Mode
The display incorporates a self-test mode composed of two patterns displayed
for approximately 30 seconds each, and then repeated. The patterns are as
follows: Diagonal Lines, Diagonal Lines Inverted, Full On, 1 x 1 Checkerboard,
and 1 x 1 Checkerboard Inverted. The self-test mode is entered by resetting or
applying power to the display with the VCLK signal static. The display will
remain in the self-test mode until two edges of VCLK are detected.

Generating Grayscales
Some applications may benefit by using grayscales. The PR2 has a maximum
frame rate frequency of 120 Hz. Using the higher frame rate, combined with
flat panel controllers designed for this faster display, it is possible to generate
usable grays through frame rate control and dithering. Video controllers from
manufacturers such as C&T and EPSON use these methods with proprietary
algorithms to generate grayscales.
The response time of electroluminescent displays is much faster than LCDs,
therefore not all possible grayscales generated by the video controller are actually
usable. Many of the grayscales may flicker or swim. Careful testing is necessary to
select appropriate grayscales for an application, especially when the
electroluminescent displays are driven at less than their maximum frame rate. For
additional information, refer to Planar Application Note 119 or contact Planar's
Application Engineers.

Component Envelope
The component envelope shown in Figure 4 illustrates the distance

this area. Planar reserves the right to relocate components
within the
constraints of the component envelope without prior customer notification.
For this reason, Planar advises users to design enclosure components to be
outside the component envelope.
An air gap of at least 5 mm is recommended to dissipate heat from display
components. Device designers will need to consider their specific system
requirements to determine the necessary spacing.
