The client, in this case, is a leading manufacturer in the heavy industry. They specialize in producing equipment such as cranes, bulldozers, and excavators. Since LCD is a top priority for industrial computers (IPC), the client thus used the touch modules provided by their LCD supplier in their products.

CHALLENGE

Excavators are usually parked outdoors. The machine must have good UV radiation resistance to ensure its best performance. However, hazing and air bubbles appeared when the client performed a UV test on the touch module. The client has successfully collaborated with AMT, so they turned to AMT to seek a better solution.

SOLUTION

After an in-depth examination, we found that the original touch module does not have an anti-UV design. This leaves the plastic vulnerable to sunlight which causes yellowing, white fog, bubbles, and even cracking of the touch panel. AMT projected capacitive (PCAP) touch products with anti-UV design pass the ASTM G154 Cycle 1 for 1,000 hours & MIL-STD-810H Pro 1 for 1,000 hours test and can meet the customer's full-spectrum test specifications. Display readability is generally low under direct sunlight, but the optical bonding service provided by AMT could avoid such issues. Lucent Gel is silicon-based. Compared with acrylic-based LOCA, Lucent Gel has higher stability and stronger resistance to extreme temperatures and UV. There is rarely cracking, foaming and yellowing caused by UV. It is a perfect choice for outdoor applications!

OUTCOME

With the touch module already incorporated into the design, the cost of re-modifying the mechanism will be too high. To cope with the issue, AMT customizes the touch module to meet the needs of the customer's organization. The client trusts AMT can deliver an anti-UV, very readable and weather-resistant product with satisfying quality and placed the order with us!
