A 15.6-Inch LCD and Capacitive Touch Assembly with Air Bonding
This Ever Glory 15.6-inch touch display module combines an LCD with a G+G capacitive touch panel. The two components are joined around the perimeter, leaving an air gap in the viewing area. This construction is known as air bonding or frame bonding.
It provides an integration option for equipment projects where assembly design, project cost and access to individual components are important. Indoor HMI systems and compact self-service terminals are examples of applications in which this construction can be evaluated.

USB communication and the listed 5 V supply apply to the touch controller. They do not specify the LCD video input or the power required by the complete display and backlight system.
Understanding the Air-Bonded Structure
G+G and air bonding describe different parts of the assembly. G+G identifies the glass-based construction of the capacitive touch panel. Air bonding describes how that touch panel is attached to the LCD.
In the viewing area, the assembly can be understood as:
- G+G capacitive touch panel: the touch-input component at the front of the assembly.
- Air gap: the space between the touch panel and the LCD, with attachment around the perimeter.
- LCD: the component that displays the image.
Unlike optical bonding, this construction does not fill the viewing-area gap with a transparent optical adhesive.
Evaluate Assembly Cost and Service Access Together
Air bonding avoids the full-area optical bonding step between the touch panel and LCD. It can therefore be considered when comparing assembly methods, but the final project cost still depends on the components, mechanical design, tooling and quantity.
The construction may also allow the touch panel and LCD to be serviced separately. For example, replacement of a damaged touch component can be considered when the LCD remains intact and the mounting and adhesive arrangement permits disassembly.
When to Compare Air Bonding with Optical Bonding
Choose the bonding method according to the installation environment and service requirements—not the screen size alone.
- Indoor interfaces: evaluate the air-bonded module under the actual lighting, viewing distance and mounting conditions of the equipment.
- Bright locations: include reflections from the air-gap interfaces in the optical assessment. Optical bonding can reduce these internal reflections.
- Service access: compare the repair procedure for each proposed assembly rather than assuming that every air-bonded design is easily repairable.
- Dust, moisture and mechanical loads: evaluate the enclosure, perimeter construction and mounting supports as part of the finished system.

Integration Points for Equipment Manufacturers
- Mechanical fit: review the module outline, viewing opening, available depth, connector access and mounting arrangement.
- Display and touch connections: assess the LCD video connection separately from USB touch communication.
- Power design: account for the LCD, backlight and touch controller individually.
- System validation: test the assembled interface with the intended host, power supply, enclosure and application software.
Frequently Asked Questions
Does this product include an LCD?
Yes. It combines a 15.6-inch LCD with a G+G capacitive touch panel. It is a module for equipment integration, not a standalone touch overlay.
Is air bonding the same as optical bonding?
No. Air bonding leaves an air gap between the touch panel and LCD in the viewing area. Optical bonding fills this gap with a transparent optical adhesive.
Does USB carry both touch data and the display image?
The specified USB connection is for touch data. The LCD requires a separate compatible video connection. The listed USB 5 V supply also refers to the touch controller, not the entire display system.
Can a damaged touch panel be replaced without replacing the LCD?
Separate replacement may be possible if the LCD is undamaged and the mechanical and adhesive design allows disassembly. The repair procedure must include protection of the remaining components and appropriate reassembly checks.
Is this construction automatically suitable for outdoor equipment?
No. Air bonding alone does not establish outdoor suitability. Readability, temperature, enclosure sealing and condensation risks need to be assessed for the complete installation.
What information helps you review an OEM or ODM enquiry?
Share the equipment application, installation environment, enclosure drawing, host platform, touch requirements and expected quantity. Include any service-access requirements so they can be considered alongside the initial assembly design.
