EL640.480-AF1 VGA Display

This manual describes the Planar ICEBrite EL640.480-AF1 display. This 6.4" diagonal VGA product offers designers an affordable and easily implemented path to dramatic visual improvements over passive LCDs.

Utilizing Planar’s proprietary ICEBrite (Integrated 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. This display utilizes a common 8bit FPD-type interface compatible with most LCD video controller chips, making it easy to integrate and to replace existing LCD displays.

Through simple design and advanced manufacturing technologies, Planar’s new VGA display family brings the visual performance and image quality of EL into cost-sensitive applications that have up to now been limited by the performance of LCD displays.

Features and Benefits

• Excellent visual performance: High brightness and contrast Wide viewing angle

Options

• Significant reduction in cost over previous EL technology

• Reliable, long operating life

• Extremely rugged and durable

• Low EMI emissions

• Rapid display response

• Low power design

Anti-glare and conformal coating options are available on this display.

The anti-glare option adds an anti-glare film to the front of the display to reduce specular reflections (see Application Note 135 for more information).

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 (see Application Note 122 for more information).

Installation 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

Mounting

The AF1 display was 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.

To prevent injury in the event of 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 Vac ). Do not touch the display electronics during operation.

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.

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.

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 Planar Application Engineering for more information.

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.
