Display Tech: Fortifying Industries with EMI Shielding

28-09-2023 | By Jack Pollard

In an age where technology reigns supreme, the world is more interconnected than ever before. Every device, from the smartphone in your pocket to the advanced machinery in industries, communicates in a symphony of electronic signals. Yet, with this digital crescendo comes a challenge that cannot be ignored: Electromagnetic Interference (EMI). As devices proliferate and our reliance on them intensifies, the importance of EMI shielding has skyrocketed. It's no longer just about ensuring your radio doesn't pick up unwanted signals; it's about safeguarding critical data, ensuring the reliability of life-saving medical equipment, and protecting the integrity of defence systems.

In the demanding realm of defence applications, TFT (Thin-Film Transistor) display assemblies must transcend being mere components. They are meticulously engineered solutions, crafted with precision, ensuring ruggedness, shock resistance, and vibrational tolerance. This commitment to excellence ensures that every device stands resilient, even in the most challenging environments.

Enter Display Technology, a beacon in this complex landscape. Aware of the challenges and the immense responsibility, they have championed the cause of pioneering robust solutions tailored for industries where there's no room for error. From medical to safety engineering, and onto the frontlines of defence, Display Technology stands as a vanguard, ensuring that as the world grows more connected, it also remains secure.

The Rising Challenge of Electromagnetic Interference (EMI)

As the digital age advances, so does the intricate web of electronic devices that power our daily lives and critical operations. These devices, while revolutionary, come with their own set of vulnerabilities. One of the most pressing of these is Electromagnetic Interference (EMI). EMI, in its essence, is the disruptive force that can wreak havoc on electronic circuits, potentially leading to data corruption, malfunctioning devices, and in some cases, complete system failures. Imagine a hospital where medical equipment gives inaccurate readings, or a defence system that misinterprets a signal due to EMI. The consequences can be dire.

This is where the significance of EMI shielding becomes undeniably clear. For industries where the stakes are high—where reliability isn't just a desirable trait but an absolute necessity, and where security can mean the difference between success and catastrophe—EMI shielding is the unsung hero. It acts as the protective barrier, ensuring that devices operate as intended, data flows remain pure, and critical systems remain uncompromised. In this relentless battle against EMI, it's not just about keeping unwanted signals out, but also about ensuring that the right signals get through, loud and clear.

Display Technology's Innovative Solutions

In the realm of EMI shielding, innovation is the key to staying ahead of the curve. Display Technology, with its forward-thinking approach, has been at the forefront of introducing groundbreaking solutions to tackle the challenges posed by EMI. One of their standout innovations is the transparent EMI glass enhanced with Indium Tin Oxide (ITO) technology. This isn't just any glass; it's a marvel of modern engineering.

At first glance, the transparent EMI glass might seem like a regular pane, but its capabilities are anything but ordinary. Infused with ITO technology, this glass offers the dual benefits of maintaining crystal-clear transparency while acting as a formidable shield against EMI. It ensures that visuals remain sharp and uncompromised, all while expertly dispersing electromagnetic interference. This means that whether you're looking at a critical readout on a medical device or a strategic map in a defence control room, clarity and security go hand in hand.

Custom Solutions and Enhanced Protection

But the marvels of Display Technology don't end there. Recognising the unique demands of each defence application, they offer bespoke customisation, tailoring displays to precise specifications. Whether it's a compact device for on-the-go operations or a large-scale display for command centres, Display Technology ensures optimal performance in every scenario.

But Display Technology didn't stop there. Identifying the need for an added layer of protection, they incorporated copper mesh into their EMI shielding solutions. With its exceptional conductivity, copper mesh not only enhances the EMI shielding capabilities but also ensures a minimum transmission rate of 90%. It's like adding an extra layer of armor, ensuring devices remain resilient even when faced with the most challenging electromagnetic conditions.

Completing the EMI shielding circuit is the silver-coated frame. More than just a structural component, this frame envelops the EMI glass and plays a pivotal role in grounding. Acting in tandem with the other components, it efficiently dissipates unwanted electromagnetic energy, neutralising interference. In essence, it transforms the entire assembly into a modern-day Faraday cage, offering an unparalleled level of protection against EMI.

Protection isn't just about shielding from interference; it's also about safeguarding against the elements. Display Technology's optical bonding process acts as a formidable barrier, preventing the infiltration of moisture, rain, and other fluids. This ensures the display's unwavering functionality, even when faced with environmental challenges, making it a trusted choice for coastal and maritime defence deployments.

With such innovative solutions, Display Technology is not just addressing the challenges of today but is also paving the way for a more secure and reliable digital future.

Beyond EMI Shielding: Enhancing Display Performance

While EMI shielding is undeniably crucial in our digital age, Display Technology understands that it's just one piece of the puzzle. For a display to truly stand out, it needs to offer impeccable performance, clarity, and durability. Recognising this, Display Technology delves deeper into the realm of display enhancement, with optical bonding being one of their standout solutions for TFT display assemblies.

Optical bonding is more than just a buzzword; it's a transformative process that takes display performance to the next level. By bonding a cover glass or touchscreen directly to an LCD cell, it eliminates the pesky air gaps that can compromise display quality. The result? A significant reduction in reflections and minimised glare. Whether you're viewing the display under the bright noon sun or in a dimly lit room, the content remains clear, vibrant, and easy on the eyes.

Advanced Features and Benefits of Display Technology

But Display Technology doesn't settle for standard optical bonding. They've taken it a step further with their proprietary VacuBond® process. This unique technique involves inserting a high-quality Opto Gel between the cover glass or touchscreen and the LCD in a meticulously controlled clean room environment. The outcome is nothing short of spectacular. Light reflection on the surfaces is reduced by up to a staggering 99 percent. This ensures that displays not only offer outstanding readability but also boast perfect contrast and colour brilliance, regardless of the ambient lighting conditions.

Moreover, in the challenging terrains where defence personnel often operate, the weather can be unpredictable. Recognising this, Display Technology has incorporated cutting-edge touchscreen technology into their TFT display assemblies. This ensures precise interaction, even when gloves are a necessity, allowing for reliable data navigation and command input, irrespective of the weather conditions.

In essence, Display Technology's commitment goes beyond just shielding against interference. They're reshaping the very essence of what a top-tier display should be, offering a visual experience that's second to none.

Display Technology's commitment to excellence is further exemplified by their seamless integration with embedded technology. These embedded systems, engineered to the highest standards, ensure uninterrupted operation even in the harshest environments. From real-time data processing to rapid decision-making, Display Technology's solutions empower defence personnel with the tools they need for success.
