Supporting LCD panels up to 32 inches in size, AMT brings extensive expertise to the table, overcoming the unique challenges associated with various LCD panel types. AMT supports all types of bonding:

• Touch panel, Cover glass, Plastic housing
• All types of bonding, including flat, irregular, or curved surfaces
• Bezel LCD, Cell Tape LCD, Open Cell, OLED, EPD

ePaper Optical Bonding

In response to the rising global focus on environmental sustainability and energy efficiency, there is a surge in demand for ePaper (or EPD) technology, amplifying the spotlight on ePaper display optical bonding solutions. The main challenge in optical bonding EPD and Ch-LCD in the thinness of the glass substrate, therefore, excessive or uneven pressure applied during the bonding process can cause the glass to break. On the other hand, the traditional liquid bonding may result in adhesive overflow, and the curing shrinkage of the adhesive can lead to Mura issues.

To tackle these two pain points, AMT utilizes solid OCA (silicone-based) in the optical bonding procedure. The pressure and debubbling pressure used in vacuum bonding are low. Combined with our self-developed bonding fixtures, this approach avoids excessive pressure and uneven pressure during bonding. And also reduce the occurrence of stress-related mura. Furthermore, we can apply a cover glass on the surface of the EPD/ Ch-LCD for additional protection or add a front light guide on the EPD, allowing users to see the screen content clearly under low-light environments. To make the equipment more weather-resistant, we can incorporate anti-UV designs into the structure to prevent LCD yellowing or cracking.

Unique Optical Bonding Technology

AMT offers comprehensive optical bonding solutions catering to a wide spectrum of client needs. Beyond bonding touch panels to LCD panels, we specialize in servicing customers whose applications don't necessitate touch functionality. For clients desiring cover glass bonding to safeguard LCD panels and incorporate specialized surface treatments or value-added features, AMT stands ready to deliver. Utilizing silicone-based OCA, our optical bonding elevates the reliability of LCD panels, meeting the varied application demands across industries including industrial, medical, automotive, outdoor products, and beyond.

Some LCD panels on the market tend to have a narrow frame design. When the frame of the LCD panel is very narrow with a thicker SOCA, after optical bonding, a bright line at the edge of the active area might be seen when looking at the LCD panel sideways. AMT uses a special process and optical bonding technology to remove the bright line when you look at it sideways.

Curved LCD or Dual-Screen Optical Bonding

Innovative products are increasingly incorporating curved screens, such as automotive dashboards or gaming devices, to offer a unique and attention-grabbing design. On the other hand, in transportation applications, dual-screen designs involve bonding two displays onto a single glass. This provides design safety assurance, as the system can still function if one fails. Such designs are becoming more common. AMT's exceptional optical bonding technology excels in supporting bonding for curved displays or dual screens, ensuring durability and reliability in demanding environments.

AMT Optical Bonding Features
