A For outdoor applications, it’s essential to use OCA/OCR with anti-UV protection to prevent yellowing and maintain optical clarity under sunlight exposure.
-
A 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.
-
A 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).
-
A 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.
-
A Optical bonding is essential for LCDs operating in high-ambient light environments or rugged conditions where readability and durability are critical. You should specify optical bonding when your application requires the elimination of internal reflections (air gap removal), prevention of moisture condensation/fogging, or enhanced structural resistance against mechanical shock and vibration.

A The primary difference lies in the adhesive state: OCA (Optically Clear Adhesive) uses a pre-cut dry film, while LOCA (Liquid Optically Clear Adhesive) utilizes a liquid resin. OCA is ideal for high-volume production of standardized flat screens, whereas LOCA is the superior choice for large-format industrial displays, curved surfaces, and uneven gaps due to its superior gap-filling capabilities and reworkability.
