AbraxSys Sunlight Readable LCD Flat Panels and Touch Screen Computers

Sunlight Readable LCD Technology - The AbraxSys Way

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 High Brightness Sunlight Readable Rugged Industrial LCD Flat Panel Displays Technology

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 AbraxSys Backlight Enhancement Technologylevels 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 performance.

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.

Key Benefits
• Increased contrast ratio with matched reflective laying
• Decreased backlight wattage while increasing sunlight viewability
• Bonding improves the overall integrity of the entire flat panel
• Eliminates "Greenhouse" effect caused by air between glass and screen
• Eliminates isotropic "black outs"
• Optical 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 U.S.A.

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.
