EL552.256-Q2 Display

The EL552.256-Q2 thin film electroluminescent (EL) display is a highperformance 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 Enhancement (ICETM) 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.

Features

♦ Excellent visual performance:

High brightness and contrast Wide viewing angle > 160°

♦ Rapid display response < 1 ms ♦ Low EMI emissions ♦ Extremely rugged and durable ♦ Reliable, long operating life with > 30,000 MTBF ♦ Separate DC/DC converter ♦ 4-bit LCD-type interface

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.

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.
