OCA – Optically Clear Adhesive

An optically clear liquid adhesive used to bond touchscreens and displays devices to the coverlens.

By using this type of adhesive, you improve the optical characteristics of the display as there are no air gaps between the coverlens and display, meaning less light reflection.

The use of adhesive also increases the durability of the display unit.

Advantages of using OCA are:

• adhesion to non-even surfaces
• better readability
• more durable display
