1. Take your time to select the proper display
for your application. Selecting the wrong display in the
beginning of your project can lead to disasters further
down the road. If you would like assistance in this area,
contact one of our display
specialists to get started in the right direction.
2. Use anti-reflective or anti-glare coatings
on all surface areas, whenever possible. These will help
bring to contrast ratio closer to it's original "dark-room"
reading.
3. When applying a touchscreen, or other
device in front of your LCD display, select the display
with the highest transmissivity ratio among those that
are durable enough to stand up to the application you
product is designed for. Many manufacturers make resistive
touchscreens with transmissivities as high as 92-95%,
including: Fujitsu,
Gunze, and others.
4. Work with a professional company, such
as FPD Group, to do "behind-the-glass"
enhancements -such as improved light guides, improved
optical filters, etc. These enhancements often provide
up to 40% increased transmissive brightness (and, in some
rare cases, can even double the transmissivity of a display).
5. Make sure polarization of any devices
in front of your LCD (such as a touch screen or various
filters) are compatible with that of your LCD. Place the
device in front of your LCD in direct sunlight and turn
the device that lies in front. If the device yields a
picture that is more sunlight readable when it is skewed
from the way it is supposed to be placed to begin with,
then you may need to switch touchscreens or ask your touchscreen
manufacturer to adjust their touchscreen to be compatible
with your display. Because of this, higher transmissivity
touchscreens may not show as well in direct sunlight as
those that are less transmissive, but are more properly
aligned.
6. Have your display enhanced to be transflective,
by FPD or other reputable companies
-this process often integrates some of the steps mentioned
earlier for best results.
7. If all else fails, look into "active
enhancements" such as backlight replacement or (be
very careful here) overdriving the backlights. For the
best display, you may even want to use anti-reflective
or anti-glare filters in conjunction with actively enhanced
displays.
If that doesn't work, or if you'd like some help with
any of the processes mentioned above, contact
