Optical Bonding

Kristel has over 28 years of optical bonding experience in the display field. Our proprietary process has produced hundreds of thousands of bonded displays already in the field, with excellent proven reliability.

Optical bonding is a manufacturing process in which a layer of optically clear adhesive is applied between two optical elements, such as a display panel and a cover glass. This creates a single optical unit with improved optical performance, such as increased contrast and brightness. Optical bonding is also used to improve the durability of the display, as the adhesive helps to protect the display from scratches and other damage.

There are two main types of optical bonding: UV curing and thermal curing. In UV curing, a UV-curable adhesive is applied to the two optical elements and then cured using ultraviolet light. In thermal curing, an adhesive that cures at high temperatures is applied to the two optical elements and then cured using heat.

Optical bonding is a common process used in the manufacturing of a wide variety of displays, including LCD, LED, and OLED displays. Here are some of the benefits of optical bonding:

• Improved optical performance: Optical bonding eliminates the air gap between the two optical elements, which improves contrast and brightness.
• Increased durability: The adhesive used in optical bonding helps to protect the display from scratches and other damage.
• Reduced manufacturing costs: Optical bonding can help to reduce manufacturing costs by simplifying the assembly process.

If you are looking for a way to improve the optical performance and durability of your display, consider using optical bonding.
