How does optical bonding work?

With an optically bonded display, Assured Systems sells industrial monitors and panel PCs that are more resistant to vandalism, have less refraction and glare, have better touchscreen accuracy, and don't condense.

TFT LCDs are vulnerable to glare and reflection from bright lights or direct sunlight. There is almost always an air gap between the TFT panel and the cover lens in TFT LCDs. When used in high-brightness installations, an air gap results in repeated refraction between each component level of the display. Without having to increase the screen's brightness, optical bonding can increase contrast and improve the screen's readability in bright outdoor or indoor environments by reducing reflection inside these components.


How does optical bonding work?

A layer of resin is placed between the glass or touchscreen and the TFT LCD TFT panel of a monitor during the optical bonding process, fusing them to create a solid laminate with no gaps or pockets of air. You should consider the setting and usage requirements the screen must withstand when selecting a screen for any project. Rugged industrial-grade screens and panel PCs are built with a wide range of features to withstand a variety of applications. Optical bonding is one such feature that can be taken into account.


Which sectors are ideal for optical bonding?

The military, marine, medical, transportation, and retail industries all use optical bonding because of the demanding environments in which they operate. Industries that frequently use tough displays in high-reliability settings or where displays must be viewed in bright environments are good candidates for optical bonding. Devices that operate outdoors or in areas with bright lighting are particularly well-suited to and significantly more effective when using the optical bonding process.


The front glass of the screen is layered onto the LCD module during the manufacturing process of LCDs, including touchscreen LCDs. Standard viewing environments don't present a problem, but under certain circumstances, such as outdoor placement, the slight space between the two layers may reduce viewing quality.


What advantages does optical bonding have?

The light from the LCD reflects through the gap and then the outer glass of the screen creates the display on a non-optically bonded monitor. When light passes through the gap and glass of the screen, it is interrupted and bent, and some of the light is reflected to the LCD module; this is known as refraction. Refraction through the layers reduces the intensity and clarity of the final image, lowering brightness and readability. By bonding the LCD module and glass together, you eliminate interruptions and the possibility of light reflection. Because more light penetrates the screen's surface, the image appears brighter.


1. Refraction is reduced by optical bonding

When an external source of light strikes the screen, the same principle is applied. The gap between the glass and the LCD module on a non-bonded screen allows for refraction, which bounces external light back off the screen to the viewer as glare. Light passes through the bonded layers and is absorbed somewhat into the screen when they are bonded together. As a result, optical bonding is critical in making screens sunlight readable.


2. Glare is reduced by optical bonding

Optical bonding increases the physical durability of screens. In optical bonding, an additional resin layer absorbs shock. This ensures long-term durability in public areas, factories, and other harsh environments.


3. Durability is increased by optical bonding

The most obvious advantage of adding a resin bonding layer between the glass and the LCD module is that it physically prevents dust and liquid ingress. Because of the high quality of manufacturing, dust, and water aren't a big issue for screens in normal environments. Condensation between the glass and the LCD panel, on the other hand, can be a problem in environments with wide temperature ranges or fluctuating humidity. Condensation can cause foggy screens due to moisture that enters the air gap. Again, the physical filling of the gap prevents this issue from occurring. As a result, optical bonding should be considered for any outdoor application as well as any indoor application where consistent temperatures are not maintained.


4. Optical Bonding Prevents Condensation

Because the pressure is maintained through the substrate rather than being delayed by a gap, a touch monitor with optical bonding maintains a more accurate touch response.


5. Optical bonding improves precision

Services for Optical Bonding

Assured Systems works with industrial display designers and manufacturers to create optically bonded touch screens. Their displays or touchscreen displays can be optically bonded to eliminate the air gap inside the screen. Please contact Assured Systems if you require an optically bonded display or an optically bonded panel PC.
