What should be considered when performing optical bonding for outdoor products?

For outdoor applications, it’s essential to use OCA/OCR with anti-UV protection to prevent yellowing and maintain optical clarity under sunlight exposure.

How does optical bonding impact cost and lead time?

Cost depends on display size, adhesive type, and production volume. Optical bonding adds value through longer lifespan, better visibility, and improved durability, often reducing maintenance and replacement costs over time. Fannal provides flexible quotation and sample testing before mass production.

Does optical bonding affect touch performance?

No. Optical bonding actually improves touch performance by reducing the air gap between layers, resulting in faster response and more accurate detection, even under gloves or wet conditions (depending on touch sensor type).

Can you bond customer-supplied LCD modules?

Yes. Fannal supports OEM optical bonding — integrating customer-provided LCD modules with our custom cover glass, touch screen, or AD board while ensuring full optical and electrical compatibility.

Custom Optical Bonding Service

Our bonding technologies ensure strong adhesion, minimal reflection, and high reliability across industrial, medical, and automotive applications.

Bonding Technologies


Optical Bonding	Size Range	Notes
OCA	Up to 15.6”	Two fully automated production lines for high-volume manufacturing
LOCA / OCR	Up to 32”	Excellent for high contrast and durability
Silicone	Up to 32”	Ideal for rugged, large-size industrial applications

Full Black Touch Display Module

Based on optical bonding technology, FANNAL adjusts various parameters to achieve a Full Black Touch Display Module.

When TFT is powered off the VA area looks similar to black as the cover BM. The color difference between the cover BM and the TFT VA can be △E ≤2

This effect can be achieved through multiple techniques, including ink formulation, monochrome OCA, or monochrome glass.

Flexible Display Options for Optical Bonding

The display can be either a original panel or a customized display provided by FANNAL, depending on project requirements.

These brands are our long-term strategic partners.

For customers with preferred display suppliers, FANNAL offers procurement and full optical bonding integration for original panel(you can choose the brand) and touchscreen modules.

Competitive Pricing: With bulk sourcing for multiple projects, we achieve cost advantages through centralized procurement.

Ready Stock for Common Models: We maintain inventory of frequently used display models to ensure faster delivery and stable supply.

Case Studies

Success stories from clients from various industries, to see if there are similarities with your requirements.

Dust & Fog-Free Optical Bonding

Customer Issue: Previous in-house bonding caused visible dust between panels, resulting in poor appearance. Additionally, screens experienced condensation in winter, leading to display issues.

FANNAL Solution: Using optical bonding technology, air gaps between panels are eliminated, enhancing both aesthetics and durability.

Result: The displays are now dust-free and clean, free from condensation issues, seamlessly integrated, visually more appealing, and overall quality has significantly improved.

One-Stop Optical Bonding Solution

Customer Issue: The customer previously had to work with separate suppliers for displays, touch panels, and bonding, making the process complex, costly, and hard to manage.

FANNAL Solution: FANNAL offers a three-in-one, one-stop solution: sourcing original displays, customizing touch panels, and performing in-house optical bonding, all under unified management.

Result: Reduced costs, controlled inventory, stable quality, simplified process, and a more reliable, aesthetically pleasing final product.
