AbraxSys is Increasing the Performance Level of it’s 15” and 15.6” LED Displays with IPS Technology

AbraxSys announced today that it is increasing the performance level of its entire line of 15” (4:3) and 15.6” (16:10) LED-backlit LCD products to utilize In-Plane Switching technology. This is a major move to vastly increase the viewing angles of our 15” and 15.6” LCDs and continue offering the highest performing rugged LCD technology. The full transition is slated to take place late second quarter 2015.

In-Plane Switching (IPS) was one of the first significant improvements in the light-transmissive characteristics of TFT panels. Co-developed by Hosiden and NEC, IPS technology solves two main issues of a standard twisted nematic (TN) TFT display: Color and viewing angle.

IPS Technology

With IPS, the crystals are horizontally aligned across the screen rather than vertically, and the electrical field is applied between each end of the crystal molecules creating a lateral electric field. In this way, the crystals are kept parallel to the the electrode pair, which is parallel to the glass substrate of the screen. The liquid crystal molecules are not anchored to the lower glass substrate, therefore they resolve quickly into the desired alignment.

In a TN TFT display when one end of the liquid crystal is adhered to the lower glass substrate and a voltage is applied, the crystal compounds uncoil, altering the angle of polarization of the transmitted light. A downside of basic Twisted Nematic technology is that the alignment of liquid crystal molecules changes the further away from the anchored electrode, turning at right angles to the substrates. This degrades the flow of light causing diminishing contrast, impaired brightness and altering color definition at wider angles to the screen. IPS vastly improves viewing angles of TFT monitors.

“Industrial” grade versus “Consumer/Commercial” grade LCD products

Many “industrial-grade” product manufacturers sell on solely on ‘price’ and in doing so they must compete in terms of selling prices with other less-costly “industrial-grade” product manufacturers. How do they sell so cheaply? It’s simple….most repackage consumer grade off-the-shelf LCD monitors. They extract the LCD and electronics, reassemble them in cheaply made metal housings and call them Industrial Grade.

Certainly, AbraxSys could purchase these types of consumer grade products from the same distribution channels and repackage them in similar housings and enter the “cheaply made industrial grade LCD” marketplace. But AbraxSys’ business model is different and as such an alternate path was chosen in terms of engineering high-quality, innovative rugged computer systems and LCD products.

In order to effectively combat 24/7/365 usage, high humidity environments, extended operational temperature applications, DC power spikes, etc., during the initial product design stages AbraxSys carefully considers each component to be utilized within a specific design so as to ensure that the finished product can withstand such harsh treatment.

The weakest electrical component within an “industrial” grade system dictates how effective the overall product will be in demanding applications. Use the cheapest integrated circuits, liquid crystal displays, power supplies, high-voltage inverters and you’ll have a product destined for problems. AbraxSys selects only the highest grade ‘parts’. The ruggedness of these internal components and their inherent tolerance to harsh environments provide a display instrument with truly “industrial” capabilities.

In contrast, other manufacturers jockeying for price must utilize the cheapest cost components available in order to maintain a competitive price advantage in the “cheaply made industrial grade LCD” marketplace. This includes the use of low-to-mid-level LCD panels, controller boards, critical power components, etc.

Often the “budget-grade industrial” LCD company has no idea who even actually manufactured the most critical internal system components within “their” monitor as they simply purchased a plastic-desktop LCD, removed the plastic housing and transferred the LCD and existing electronics housing into their enclosure. There’s been no thought given to graphics chipsets, end-of-life (EOL) time-frames for components, integrated circuit quality, power supply and inverter reliability data, grade level of LCD panel, etc. AbraxSys, on the other hand, can explain in detail every component, its performance characteristics, EOL, etc.

Varying operational temperature extremes will have a negative impact on electronics. So, AbraxSys utilizes a number of unique thermal management systems which makes the displays fit for the harshest temperature environments. Some of AbraxSys’ models can even operate effectively for long periods of time at -40°C / -40°F MIL-STD-810F to +70°C / +160°F MIL-STD-810F. “Budget” type products certainly don’t offer such safeguards.

As devices for displaying various types of information and images in many diverse environments, customers are demanding greater sophistication and diversity from displays. To meet the growing demand for higher image quality, greater energy efficiency, and improved environmental performance such as greater resistance to shock and vibration and operational temperature capabilities, AbraxSys selects only the highest quality LCD modules. The results are easily seen in outstanding image reproduction, vivid images in any ambient light environment, wider viewing angles, greater color gamut and much, much more. Original Equipment Manufacturers of amorphous-silicon color thin-film-transistor (TFT) liquid crystal display (LCD) modules take into account the special needs of the industrial market and leverage cutting edge technology and cultivated know-how that it then uses in the design of their advanced true “Industrial Grade” LCD modules.

Here again in contrast, the low-end ‘industrial’ display “manufacturers” must purchase only cheaply made office/home grade LCD panels.  We truly do build top-end systems and do not try to compete with the cheaply made units often coming out of Asia and/or local “repackaging” companies.  And, we offer an exceptional THREE YEAR WARRANTY for most models.

What does half-life mean in terms of an LCDs backlights?

Half Life

In scientific terms, half-life pertains to the amount of time it takes for a substance to decay by half. Similarly, the same term pertains to Light Emitting Diodes (LEDs) describing the amount of time before a display’s brightness degrades to half of its original intensity. It may still be viewable at this point, but it won’t be as visually appealing or effective as it was when it was first switched on. So, why is this information important to you, as a consumer? Well, quite simply put, you’ll want a product that is able to withstand the test of time. Owners of any LED sign, no matter the size or shape, will likely be interested in keeping it working for as long as possible. Most LED’s these days maintain a half-life between 60,000 to 80,000 hours, some few systems 100,000 hours (like those from AbraxSys).  What this means for consumers is that with constant un-interrupted use at maximum brightness, an LED will be at half of its original brightness in 7 to 11 years. Granted there are other external forces that can affect sign quality, but many can be avoided with proper maintenance and precautions.

The Benefits of Conformal Coating

Many chemicals found in the oil, gas, and petrochemical industries can consign electronic components to a short life, creating high failure rates and low reliability. Corrosive agents such as H2S gas, hydrocarbons, chlorobenzene, and chemical by-products play havoc with components that control and manage processes, or transport vital data between control centers and remote sites. What is required is a protective coating that can isolate the components from the harsh reality of industrial settings.

AbraxSys Industrial Rugged LCD Monitors and Touch Screen Computers - Conformal Coated ElectronicsConformal coatings, as the name suggests, do just that by conforming to the contours of elements that populate printed circuit boards (PCBs) and other components present in electronic assemblies and systems. Conformal coatings are thin layers of synthetic resins or organic polymers applied to PCBs and electronic components for protection against environmental, mechanical, electrical, and chemical problems including contaminants such as dust, dirt, fungus, moisture, chemicals, thermo mechanical stress, mechanical shock, and vibration. Conformal coating types include urethane, silicone, acrylics, epoxies, and parylene.

A conformal coating service from AbraxSys is offered to protect all internal PCBs and components from dust, moisture, fungus, corrosion and vibration.  The coating can be brushed or sprayed onto the PCB, depending on application needs. A conformal coating can help minimize electromigration between metal conductors. In addition, the use of a conformal coating can protect circuits and components from direct contact that can lead to abrasions or electrical short circuits.

BENEFITS
Solution for Preventing Corrosion and Moisture

Coating offers protection of circuitry from moisture, fungus, dust and corrosion caused by extreme environments.

Coating prevents damage from board handling during construction, installation and use, and reduces mechanical stress on components and protects from thermal shock.

Coating resists abrasion in service.

Coating enhances performance and allows greater component density due to increased dielectric strength between conductors.

NEW INDUSTRIAL LCD PANELS WITH LONG-LIFE LED BACKLIGHTING SYSTEMS

TFT LCD Modules Feature Replaceable LED Backlights, High Brightness and Low Power Consumption

AbraxSys Solid State LED Backlight for Industrial LCD Flat Panel Monitors TechnologyAbraxSys Corporation, a committed industry leader that collaborates with customers to create breakthrough designs, not long ago began using an advanced color active-matrix thin-film transistor (TFT) liquid crystal display (LCD) module product lineup for most of its industrial applications that incorporates long-life light-emitting diode (LED) backlighting systems.  Developed by AbraxSys, the modules are designed to satisfy the requirements of a broad range of industrial applications, such as test and measuring equipment, medical equipment, portable handheld computing devices, and more, utilizing the latest LED backlighting technology.

The LED-based backlighting systems provide an average backlight lifetime of over 70,000 to 100,000+ hours, or approximately well over 8 years continuous operation, (to half-brightness of the initial luminance specification), which exceeds that of today’s common TFT LCDs for industrial applications utilizing long-life cold cathode fluorescent lamp (CCFL) backlighting systems.  AbraxSys has achieved this by applying long-life LEDs, and by optimizAbraxSys Rugged LED LCD Displaysing the thermal design of the industrial-type LED-based backlighting system based on AbraxSys’ extensive experience in utilizing LED backlighting for rugged TFT displays.  The modules have been designed with a replaceable backlight structure to accommodate the product longevity requirements, and the harsh-usage environments, of industrial, military, and marine applications.  In addition, AbraxSys has added an advacned LED driver circuitry into the electrical interface for the displays.

Compared to CCFL baAbraxSys Industrial LCD Flat Panel with LED Backlightscklit displays, LED-backlit displays feature superior characteristics such as lighter weight, lower electrical noise, lower power consumption, and offer a wider adjustable luminance range.  LED-backlit displays also reduce the environmental impact, in consideration of both material and energy consumption, since they are mercury-free1 and lower in power consumption.  Also, the new LED-backlit displays do not require the high-voltage and high-frequency circuits required to control luminance in CCFL-backlit displays, thus enabling a higher level of flexibility in system design in terms of safety, electro-magnetic interference (EMI) compensation, and system architecture.

In-Plane Switching (IPS) Technology

In-Plane Switching (IPS) was one of the first refinements to produce significant gains in the light-transmissive characteristics of TFT panels. Jointly developed by Hosiden and NEC, it is a technology that addresses the two main issues of a standard twisted nematic (TN) TFT display: color and viewing angle.

With IPS, the crystals are aligned horizontally to the screen rather than vertically, and the electrical field is applied between each end of the crystal molecules – termed a lateral electric field. In this way, the crystals are kept parallel to the the electrode pair, and thus the glass substrate of the screen. The liquid crystal molecules are not anchored to the lower glass substrate, so move more freely into the desired alignment.

Comparing TN and IPS Light Flow Through LCD Monitors

In a TN TFT display when one end of the liquid crystal is anchored to the lower glass substrate and a voltage is applied, the crystal compounds untwist, changing the angle of polarisation of the transmitted light. A downside of basic TN technology is that the alignment of molecules of liquid crystal alters the further away they are from the anchored electrode, turning at right angles to the substrates. This impairs the flow of light causing diminishing contrast, brightness and colour definition at wider angles to the screen.

AbraxSys IPS Rugged LCD Flat Panels

IPS improves viewing angles of TFT monitors considerably, but means that two transistors are needed for every pixel, instead of the one needed for a TN TFT display. Using two transistors means that more of the transparent area of the display is blocked from light transmission, so brighter backlights must be used. The increased power consumption can make the displays unsuitable for notebook use, but in higher end industrial displays viewing as a principle purpose IPS screens are employed.
