Optical Bonding or Air Bonding? Watch the video below. Optical Bonding uses optical adhesive to seamlessly bond the various layers of the screen, eliminating air gaps and achieving high light transmittance, precise touch control, strong protection, and a slim appearance. It is suitable for high-end devices and complex scenarios, but the cost is high and maintenance is difficult. Air Bonding only uses adhesive to fix the four edges of the screen, leaving air gaps, resulting in average display and touch control, weak protection, and a bulky appearance. However, the cost is low and maintenance is convenient, making it suitable for devices with limited budgets and simple needs. Choose according to your needs, and there is no need to blindly pursue Optical Bonding.
Traditional display assemblies can contain an air gap between the TFT LCD panel and touch panel or cover glass.
Optical bonding fills this gap with a highly transparent optical adhesive.
Hotdisplay's optical bonding technology can use optical adhesive materials such as:
OCA — Optical Clear Adhesive
OCR — Optical Clear Resin
The adhesive creates a more integrated optical structure between the display components.
Air bonding leaves an air layer between display components.
Optical bonding replaces the air gap with optical adhesive.
This creates a more integrated structure between:
TFT LCD → Optical Adhesive → Touch Panel / Cover Glass
Depending on the display configuration, optical bonding can help:
Reduce the air gap
Improve optical integration
Reduce internal reflections
Improve outdoor readability
Reduce the visual effect of dust or air gaps
Create a more integrated display structure
Optical bonding is especially useful when a TFT LCD is combined with a touch panel and cover glass.
Hotdisplay provides customized touch display solutions including:
TFT LCD
Capacitive touch
Resistive touch
Cover glass
Optical bonding
Customized FPC
Surface treatments
Hotdisplay can customize the display assembly according to the product design.
Customization may include:
Display size
Touch panel
Cover glass
Glass thickness
Shape
Printing
FPC
Optical bonding
Surface treatment
For outdoor displays, optical bonding can be combined with other technologies such as high brightness, anti-glare treatment and transflective display technology.
The appropriate configuration depends on the application environment.
Hotdisplay combines TFT LCD, touch, cover glass, FPC and optical bonding capabilities to develop integrated display modules.
This allows customers to work with one display engineering and manufacturing partner rather than coordinating multiple component suppliers.
