As industrial equipment demands higher display performance and reliability, optical bonding is rapidly gaining adoption. Compared to frame bonding, optical bonding eliminates the air gap between the touch screen and display layer, significantly improving transmittance and contrast while strengthening the structure and reducing dust and moisture ingress.

The readability improvement is especially noticeable in outdoor and bright-light environments. For industries with strict display quality requirements such as medical, automotive and industrial HMI, optical bonding has become the preferred choice.

Daming Optoelectronics has extensive experience in GG, GFF and PMMA optical bonding processes, offering one-stop support from solution design to volume delivery.

The core challenge of outdoor displays is strong light reflection. When an air gap exists between the touch screen and the display layer, light reflects multiple times at the interface, reducing contrast and washing out the screen. The GG glass-on-glass structure combined with OCA/OCR optical bonding effectively eliminates the air gap and reduces reflection.

After optical bonding, transmittance can exceed 90% (editable), with significantly improved contrast and outdoor readability, while the glass cover delivers higher surface hardness and durability.

For bright-light applications such as automotive consoles, outdoor terminals and industrial inspection devices, GG optical bonding is a mature solution that balances display performance and structural strength.

Non-standard touch display projects often face the pain of multi-link coordination: structural design, display selection, touch solution, bonding process and system integration are all indispensable. Daming Optoelectronics provides ODM/OEM one-stop customization — customers only need to specify size, interface and application, and we handle the entire process from design to volume production.

Customization covers size (0.96"-55"), structure (outline, cutout, stack-up), interface (I2C/USB/MIPI/LVDS/EDP) and function (water rejection, glove touch, stylus, anti-shatter), meeting diverse needs across industrial, medical, automotive and smart home sectors.

With 15 years of industry experience and integrated R&D and manufacturing, we help overseas customers shorten development cycles and reduce coordination costs, delivering stable, high-quality volume shipments.
