Many of us use devices such as smartphones and other handheld devices just about every day, but have you ever thought about how that same technology also has a hand in creating our nation’s defense systems? The defense industry might sound like a field that couldn’t be more disconnected from daily life, but because of liquid crystal display (LCD) technology, the two are inadvertently connected.

LCDs can power handheld gaming devices, smartwatch interfaces, and navigation systems in our cars. They’re so useful and so advanced that they have become a mainstay in aerospace applications, armed forces, cybersecurity, and defense manufacturing. That’s right – these everyday screens are important to advanced tools such as control panels and defensive and offensive equipment, thanks to their exceptional qualities.

The Evolution of LCD Technology

Unsurprisingly, LCD technology wasn’t always as advanced or in demand as it is now. While liquid crystals were discovered back in the late 1800s, it wasn’t until the 1960s that they were engineered for practical applications. During that time, the first working LCD display was born. Their main use was for scientific and industrial purposes because of limits in their capabilities, and the cost of manufacturing them.

Just like in many other sectors at the time, cathode ray tubes (CRT) were the most common technology in the defense industry. They were able to generate images by allowing electrons to hit a screen and light up to create an image, providing great contrast and range of color that were valuable in certain uses.

But as LCD technology progressed, it became the dominant technology in the industry. Especially in the military and aerospace spheres, LCDs were heavily used in things like aircraft cockpits and shipboard systems. The many advancements in their power efficiency, size, weight, and accuracy made them much more favorable than their older counterparts.

Role of LCD Technology in the Defense Industry

In the modern day, LCD technology continues to play a big role in the defense sector. It has weaved its way mainly into the operational side of things, helping to enhance the effectiveness and efficiency of how things function.

  • Military Aviation – Just like with regular aviation systems, LCD screens have applications in military aviation to showcase important information such as flight data, navigation guides, and system status updates to pilots. These could range from simple displays to more complicated navigational dashboards.
  • Naval Vessels – Similarly, naval vessels, including submarines and warships, also rely on the same sort of LCD displays for their operations. These LCD displays are essential for sonar systems and navigation, providing top quality images and quick response times.
  • Battlefield Management Systems – When it comes to battlefield management, LCD screens can provide tactical information such as troop statuses and terrain maps.
  • Wearable Technology – Being lightweight, flexible, and energy-efficient, LCD screens are ideal for portable technology, whether handheld communication devices or wearable devices.
  • Command and Control Centers – Small LCD panels have a variety of uses in command and control centers, including threat detection, surveillance, strategic planning, and other purposes that involve real-time imaging.

Advantages of LCDs in Defense

There are numerous reasons behind the popularity of LCDs. LCD technology is novel and progressive, rendering it extremely useful for all sorts of industries. Here are a few major reasons why:

High-Resolution Image Quality

LCD displays are known for their clear and sharp image quality, which is especially crucial in important industries like the defense industry. With data easy to read and highly visible on the screen, these screens are ideal for high-pressure situations where time is of the essence. They typically also have wide viewing angles that allow an individual to view a screen from all different directions without compromising on quality.

Durability and Reliability

The defense industry requires durable and reliable systems and machinery, and LCD screens provide just that. They’ve proven their use in potentially harsh and unpredictable environments, including extreme temperature variations and places prone to mechanical shocks and environmental hazards. Because LCDs are made up of layered components and can be customized beyond their basic structure, manufacturers can tailor them to further withstand certain conditions.

Power Efficiency

In comparison to other display technologies, LCDs consume a lot less power. This is especially useful when it comes to handheld devices or devices used in remote locations where there may not be enough power resources to keep them active. There are a range of different LCD subcategories, including TFTs and AMOLEDs, which offer certain levels of energy efficiency, depending on need.

Design Flexibility

A great advantage of LCDs is their design flexibility. Their customizability allows them to fit different devices and applications and come in a variety of shapes and sizes, which speaks to their versatility.


Critical to the defense sector, the lightweight quality of LCD screens means equipment can be made much more portable. Soldiers can reduce physical strain when carrying equipment out on the field and aircraft can enjoy lower weights for better efficiency and capacity.

Backlight Visibility

Contributing to the quality of LCDs, backlighting technologies offer visibility in varying light conditions, whether overcast, dark, or bright light. There are also a variety of colors available, such as red, green, blue, white, and yellow, which can be useful in different operational scenarios.

Long Operational Life

LCDs have a long life span, which can help with cost-effectiveness and prevent operational downtime – especially relevant in the defense sector.

LCD Technology: A Driver in Defense Innovation

Considering the advancements that LCD technology has gone through, there’s no question that its applications will continue increase in value with respect to the defense industry. As time goes on and we implement LCDs in a new variety of ways, we’ll see them fulfill new needs, refine their advantages, and improve in overall effectiveness.

The endless benefits they offer, including superior image quality, durability, power efficiency, design flexibility, lightweight nature, and an impressive lifespan, have truly shaped and advanced the operations of the defense industry. In the coming years, we can expect to see this technology open new doors in the realm of strategic military operations and national security.
