Sunlight Readable LCD Technology - The AbraxSys
Behind the LCD
Due to the fact that many of AbraxSys
rugged monitors and embedded LCD computers operate in high
light environments, AbraxSys uses various passive enhancements to increase the
sunlight readability of the touch screen. AbraxSys touch panels utilize an
anti-glare surface coating, in addition to an anti-reflective internal coating on the back and front
of the LCD behind the surface coating. AbraxSys incorporates transflective backlight enhancement
film as well. The enhancements adapt to the index of refraction to decrease reflection there
by increasing the ratio of contrast and maximizes overall dyalight viewability in high ambient light
environments. (See figure below)
The typical liquid crystal display degrades
to black during exposure to direct sun and ultra violet radiation. Through the application
of AbraxSys special coatings, filters, and films, the screen achieves readability in direct
sun even when backlighting is not increased. The result is a display with viewability
equivalent to that of a 1000+ nit high bright monitor while not increasing the power draw and
without the extra heat generated by more backlights. As a result, Abraxsys LCD monitor
systems maximize the operating life cycle of the systems, yield higher processor capability,
and widen the range of operational temperatures.
AbraxSys' active enhancement is then added with AbraxSys advanced
backlighting maximizing the sunlight readability and luminance of the screen's overall performance.
AbraxSys utilizes LED and CCFL technologies to deliver the best sunlight readable solution for your
environment. LED backlights deliver a ultra bright screen with a lower power draw
than CCFL and without creating the heat levels produced by CCFL backlighting which requires higher wattage. Commercially
available LCDs typically do not provide sufficient color contrast and
luminance for operating in high ambient light environments thus producing a degraded image.
AbraxSys' ultra bright, sunlight readable monitors and embedded computers achieve
exceptionally higher luminance levels resulting in the highest image quality in high light
areas. AbraxSys' extreme-performance LCDs and computers produce the image intensity and display
brilliance required from your sunlight reabale systems.
Then we add our unique Optical Bonding procedure:
Improved contrast. Faster perception. Higher
Maximize TFT/AMLCD readability-at-a-glance performance by adding an optically bonded LCD
TFT display from AbraxSys Corporation. Combining LED backlight enhancement, optical bonding, optic
coatings, and touch screens to fulfill your interface requirements in high light areas. AbraxSys Corporation's
state of the art optical bonding production center produces proven high quality sunlight readable LCD
systems, comprehensive in-house optical contrast and luminance test verification, a certified clean room
and total environmental protections.
• Increased contrast ratio with matched reflective laying
• Decreased backlight wattage while increasing sunlight viewability
• Bonding improves the overall integrity of the entire flat
• Eliminates "Greenhouse" effect caused by air between glass
• Eliminates isotropic "black outs"
coatings diffuse reflection and reduce specular
• Much lower power draw required for battery powered devices with increased sun
• Certified clean room and other environmental protections
• Fast, responsive delivery and service. AbraxSys optical bonding systems are manufactured in
Typical LCDs are sufficient for most indoor environments, but do not
provide readability in outdoor or the requirements to deliver high performance in
rugged or extreme environment applications. For extreme applications, typical commercial monitors
are virtually unusable. The options are to decrease display washout less through passive
enhancement such as coatings and optical bonding, or increase the LCD brightness; and in many
instances, both passive and actively enhanced options. The OEM LCD companies are not produced
for operation in these extreme conditions and applications. AbraxSys' line of high performance
optically bonded LCD displays deliver high quality screen interfaces for high light or
rugged industrial environments requiring hardened systems.
AbraxSys sunlight readable solution is to combine LED light bar (rather than CCFL) for backlighting
technology, with optical coating, advanced design reflection patterns on light guide bottom, and unique
radiation technology to deliver maximum brightness and decrease power consumption from the backlight
source. Brightness is important because it affects readability. The high brightness solution increases day-time and
night-time visibility and offers a good choice of sunlight readable solution. Related applications covers from ATM,
the in-vehicle satellite television, the telephone booth, and the outdoor displays.
In order to satisfy the application market for high brightness
displays, Advantech develops our in-house high brightness technology positively, which is guaranteed to meet your
application needs. A standard LCD monitor is generally 300 ~ 500nits. Advantech high brightness solution at the
moment can help enhance the LCD brightness up to 2,000nits and meanwhile increase the color saturation and the
contrast. Moreover, our high brightness solution requires low power consumption, resulting in displays that run
cooler with minimal stress but maximum reliability.
