Why is Optical Bonding Essential?


April 3, 2023


Benefits of Optical Bonding

Optical bonding is a process that combines a display module and a touchscreen by attaching a layer of adhesive between them. While it might seem like an insignificant process, optical bonding plays a crucial role in display performance and durability, and it’s becoming increasingly popular across various industries. 

From the experts in optical bonding at Apollo Display Technologies, we’ll explore the reasons why optical bonding is essential for display technology.

Improved Sunlight Readability

One of the primary benefits of optical bonding is improved sunlight readability. When a separate display module and touchscreen are used, the gap between the two components can create contrast issues. This gap, known as an air gap, can cause incoming light to refract and scatter, affecting the contrast and clarity of the display. Through optical bonding, however, the air gap is eliminated, resulting in a reduction in reflection and glare, improving the contrast ratio and making it easier to see the display in bright sunlight or other bright environments.

Enhanced Durability

Display technology has an immense impact on everything from retail environments to aerospace and military applications, so durability is a top priority. Through optical bonding, displays can become more durable, as the bonding process creates a secure, stable, and resilient connection between the display module and touchscreen. This bond prevents dust particles or moisture from passing into the space between the touchscreen and display module, protecting the display from damage and extending its lifespan.

Improved Image Quality

In addition to enhanced durability and improved sunlight readability, optical bonding can also lead to improved image quality. The process reduces light reflection and refraction, resulting in a clear, crisp image. It also eliminates parallax error, which occurs when the touchscreen and display module are misaligned or don’t align well. By resolving these issues, optical bonding ensures that images are displayed as intended, improving the overall user experience.

Weather Resistance

Optical bonding can also make displays more resistant to inclement weather conditions, such as rain or snow. In many outdoor applications, exposure to the elements can cause water to accumulate between the display and touchscreen, leading to damage or malfunction. By bonding them together, there’s no room for water to penetrate, protecting the display from the weather’s damaging effects.
