2-3 DESIGNING FOR BETTER VISIBILITY

1) PANEL ANGLE

Visibility of LCD module deeply depends on the viewing directions. The position and the angle of LCD module in the

system should be designed so that the best visibility can be obtained at the actual usage.

2) WINDOW OPENING

Dimensions of window opening of the system's enclosure should be designed as smaller than "Viewing Area" and

larger than "Active Area" specified in individual specification in order to prevent that a part of screen is interrupted by

the enclosure and disappears.

3) PROTECTIVE COVER/

ULTRA-VIOLET CUT FILTER

In case of severe environmental condition like outdoor usage, a proper transparent protective cover (lens) over LCD

module is recommended, to prevent scratches, invasion of dust and water, etc, between the system housing and the

LCD module.

It is recommended to apply an ultra-violet filter (less than 390nm cut) onto the LCD module, for outdoor operation.

Strong ultra-violet radiation may damage the panel. However, in that case, transmittance-luminance will decrease.

Careful selection of material is required.

Don’t expose any parts, except the viewing area, into the direct sunlight, otherwise deterioration may occur.

2-4 DESIGNING LED POWER SUPPLY CIRCUIT

Make a design of stopping output, when an LED driving circuit becomes no-load (LED, FPC damage).

When the voltage input continuously with no-lighting LED, it may be smoke or fire.

For overcurrent protection, make a design of LED driving circuit with protective circuit (overcurrent

detector etc.).

To drive LED backlight, apply constant electric current by the following circuit diagram as reference. Please refer to

technical note of BD6583MUV (ROHM Co., Ltd.).

For Installation in Assembly

3-1 CARRYING

Hold a metal frame (bezel) part with both hands when carrying a LCD module with hand. Holding FPC may cause

failures, in the worst case, it may cause smoke and/or fire.
