Silicone Optical Clear Adhesive (OCA)

Silicone Optical Clear Adhesive (OCA) fills the air spaces between components in LCD displays, improving brightness and contrast. It is highly resistant to yellowing and offers excellent long-term performance. We sell our Silicone OCA in sheets for easy handling and reusability.

Features:

  • Made of high-grade silicone, this OCA exhibits excellent physical properties, ensuring stable performance.
  • Silicone OCA exhibits minimal yellowing when exposed to heat and UV radiation. It has a low temperature dependence, allowing it to operate over a wide temperature range.
  • Silicone OCA maintains flexibility and reduces stress on display components. This contributes to a more uniform displayed image and increased shock resistance.
  • Displays bonded to Silicone OCA can be reprocessed, improving performance and reducing costs.
  • Silicone OCA is available in thicknesses from 0.175 mm to 1.8 mm.
  • The maximum width of Silicone OCA is 1,280 mm. It is suitable for large displays.

Application example:


Inserting Silicon OCA between the LCD unit and the cover glass offers many benefits, such as increased shock resistance, reduced stress, increased contrast, reduced parallax, and improved brightness.
