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
