EL552.256-Q2  
EL552.256-Q2 Display  
The EL552.256-Q2 thin film electroluminescent (EL) display is a high-  
performance alternative to lower resolution LCDs and VFDs and is the  
ideal solution in demanding applications where superior visual  
performance and environmental ruggedness are critical. The display  
consists of an EL glass panel and control electronics assembled into a  
space-saving, rugged package for easy mounting and a separate DC/DC  
converter with interconnecting cable.  
The EL552.256-Q2 display utilizes Planar’s proprietary Integral Contrast  
TM  
Enhancement (ICE ) 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 4-bit LCD-type interface is TTL-compatible and is designed for  
hardware compatibility with the SMOS 1353 or equivalent LCD  
controller. Each of the 141,312 pixels has an aspect ratio of 1:1 and is  
individually addressable to clearly display high information content  
graphics and text.

Installing 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 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.

EL552.256-Q2 Operations Manual (OM410-00)  
 
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.  
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.  
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 (±0.025"). Use  
all the mounting holes provided. Failure to do so will impair the shock and  
vibration resistance of the final installation.  
The EL552.256-Q2 is a tab-mounted display. Use standoffs of appropriate length  
to assure that screws through the mounting tabs do not introduce bending stresses  
to the display. Do not deflect the ECB out of its normal plane. The EL552.256-Q2  
mounting tabs were designed for a 3 mm screw. The EL552.256-Q2 NE display  
does not have mounting tabs. Contact Planar Applications Engineering for  
information on mounting the EL552.256-Q2 NE display.  
WARNING: These products generate voltages capable of causing  
personal injury (high voltage pulses up to 230 VAC ). Do not touch the  
display electronics during operation.  
Cable Length  
A maximum cable length of 0.6 m (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.

EL552.256-Q2  
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.  
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.  
Power-up Sequence  
This display requires simultaneous 12V and 5V input in addition to video signals  
for proper operation. It is important that your design provides these signals  
simultaneously. If these signals are not simultaneous, they must meet the  
sequential timing shown in Figure 1 below.

Connector  
The EL552.256-Q2 display package includes a DC/DC converter and a cable for  
connecting it to the display. As shown in Figure 2, the display is connected to the  
converter (Connector J1 to J3) with the supplied cable, then the converter has a  
connector (Connector J0) for interfacing with the customer design.

voltage requirements for EL displays. Its input voltages are +12V only or both  
+12V and +5V.

Interface Information  
This Planar EL display incorporates 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 should select the chip set that best suits their particular  
architecture and price point.  
Video Input Signals  
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.

Self-Test Mode  
The display will enter the self-test mode if all seven video inputs (VCLK, HS, VS,  
and VID0 through VID3) are high for longer then 2.5 seconds at power up. The  
self-test scans at 100 Hz with a diagonal pattern that changes back and forth every  
2.5 seconds from 3 pixels on/1 pixel off to 1 pixel on/3 pixels off.  
After the self-test, turn the display off and wait at least 15 seconds before  
reapplying power to allow the internal capacitors to completely discharge. When  
you turn the display on again, apply video signals in less than 2.5 seconds after  
power up to enter normal operation.

Generating Grayscales  
Some applications may benefit by using grayscales. The Q2 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, SMOS, and Cirrus Logic 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, Generating  
Grayscales, or contact Planar’s Application Engineering.

The component envelope shown in Figure 5 illustrates the distance components

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.
