VBOND
Overview...
VBOND
creates Sunlight Readable LCD Monitors
without adding any backlighting enhancement. VBOND
process is equipped with a UV protected solid, transparent
bond. This procedure permanently bonds the front protective
glass overlay or touch screen directly to the frontal
face of the display.
VarTech’s
unique optical bond eliminates reflection from the
two internal layers and utilizes an adhesive that
matches the index of refraction of the flat panel
and the overlay. As well, the outer surface of the
protective window is chemically treated with anti-reflecting
coatings which matches the front surface of the glass
with the index of refraction of air. This combination
reduces the total reflection of the display and front
cover glass to less than 2% of the ambient light.
A reduction of reflection of this level, all but eliminates
reflective loss in most ambient lighting conditions.
With reductions of this level, displays with 250 to
450 nits of brightness (cd/m2), traditionally not
viewable in direct sunlight, will now be readable
in very high ambient brightness or indirect lighting
conditions.
VBOND
also removes all air gaps, therefore reducing the
number of internal reflecting surfaces which can lead
to significant degradation of the LCD’s optical
performance.

CCFL
High Bright Overview...
Our
CCFL actively enhanced High Brightness TFT
LCD Monitors are designed to operate in high
ambient light conditions. At 700 nits to 1850 nits
of brightness, VarTech's High Bright Sunlight
Readable Displays outperform commercially
available non-enhanced products that washout in direct
and/or indirect sunlight conditions.
Although a display with less than 500 nits screen
brightness and a mere 2 to 1 contrast ratio can be
read in outdoor environments, the quality of the display
will be extremely poor. A truly sunlight readable
display is typically considered to be an LCD with
700 nits or greater screen brightness with a contrast
ratio greater than 5 to 1. In outdoor environments
under the shade, such a display can provide an excellent
image quality.

LED
High Bright Overview...
This
new technology creates an amazingly bright
LCD display without increased heat usually
associated with higher wattage CCFL backlights. VarTech
LED backlight technology provides the best of both
worlds – a high bright monitor with low power
consumption and no need for additional thermal dissipation.
VarTech’s
unique LED backlighting technology was developed for
displays requiring a luminance level of at least 700
nits as required for outside viewing. When compared
to the practice of adding traditional CFFL backlights
to achieve a high bright LCD, LED
backlight technology increases the reliability of
the high bright monitor and extends its lifetime.
This
new technology creates a sunlight readable
monitor with inherit protections against
environmental factors such as shock, vibration and
frigid temperatures. LED backlighting technology enables
all these benefits while maintaining adequate thermal
levels of the LCD.
