Improved LED Backlighting
Our
newly released advanced LED Backlight technology utilizes
the very latest in LED semiconductor technology and
allows us to more precisely control the brightness of
specific areas of the screen. True backlight luminance
has been increased without compromises to thermal dissipation,
power consumption and life expectancy. The results are
a dramatically enhanced contrast with extended brightness
and dynamic range.
Other
improvements due to the new LED backlight technology
are:
-
Increased energy efficiency & thermal control
- Color
stability through active feedback
- Adjustable
white point in backlight
- Infinite
dimming without color shifts
- Motion
blur reduction
A
VarTech LED backlight panel enhances the viewing experience
of LCD display by providing better color, dynamic backlight
control and VarTech’s LEDs are environmentally
friendly and safe.
Improvements to the Optical Stack:
VarTech's
latest proprietary Optical Stack Enhancement (OSE) further
advances the performance of the electronic LCD displays
by making them brighter, clearer, whiter and more colorful.
The difference, quite literally, must be seen to be
believed.
As
light passes through a liquid crystal display, much
of it can be absorbed along the way to the viewer. In
fact, in a typical LCD display a theoretical maximum
of only 16% of the backlight's potential is realized,
in practice, this number is much lower at 8 to 10%.
The
new film enhancement technology is a unique optical
design which boosts efficiency of the backlight's light
utilization and minimizes the surface reflection of
ambient light. The result is a transmissive enhancement
that features higher contrast and a wider range of colors,
even in bright outdoor light, than traditional reflective
LCDs. This is accomplished by:
Recycling
what would be wasted off axis light and then redirecting
light towards the viewer;
Reflecting
and recycling polarized light which under normal circumstances
50% of the backlight output would have been absorbed
into the LCD and subsequently wasted;
The
integration of an advanced polarizing film which can
also make LCDs background whiter and brighter. This
new film type offers increased reflective properties
while maintaining transmissiveness. It nearly doubles
reflected brightness across the complete viewing range
which reduces the need for driving the backlight higher
and brighter therefore extending the life expectancy
of the LED backlight system and reducing battery charge.
Finally,
the use of a multilayer, ultra-high reflectivity, mirror-like
optical enhancement film that is used as a very efficient
light guide and cavity reflector with a reflectivity
of 98.5% across the visible spectrum which provides
a brighter more efficient display.
Improved Mechanical Design:
New
IP67 (NEMA 6) Fully-Enclosed, Submersible design constructed
of a Rugged Machined 6061 T6 Aluminum Enclosure.
Improved
user controls: no more membrane but rather now sealed
momentary pushbutton switches designed with a smooth
tactile feel. These switches are sealed to IP67 standards
with expected life of 500,000 cycles.
