What is Optical Bonding?
Optical bonding is implemented by either liquid or sheet form OCA. Optical bonding is the process that touch panel and LCD panel together with optical clear adhesives. Optical Bonding use liquid gel to laminate/affix the cover glass or touchscreen on the front of the LCD panel. It eliminates air gap between the touch panel and the display.
In addition, optical bonding can dramatically reduce the internal reflections and helps improve brightness and contrast ratio of display, enhance system ruggedness, strengthen shock and vibration resistance.
What are the benefits of optical bonding?
(1) Reduce reflections
Optical Bonding eliminates the reflections between display and touchscreen and reduces glare effects and mirror images. It can increases sunlight readability.
(2) Better Readability
In addition, it also increases the contrast and the optical brilliance of panel.
(3) No Condensation
In extremely temperature environments, it is easy to make screens cause moisture condensation that penetrates the air gap. With optical bonding fills the air gap can prevent condensation and fogging effectively.
(4) Enhance Ruggedness
Optical bonding not only improves impact and scratch resistance, but also strength to prevent safety issues of broken glass.
(5) Improve Sensitivity
For touch monitors with optical bonding provides accurate touch experience and making it easy to use for customers.
(6) Increase Anti-Vibration Capabilities
Optical bonding increases resistance to mechanical shock and vibration. This is especially useful for military and transportation applications.
(7) No dust and dirt particles
Optical bonding can resists stains, dirt, dust.
