터치 스크린 성공 사례
AMT resistive and projected capacitive (PCAP) touch screens, touch controllers, optical bonding, Lucent Gel, touch screen displays, and Open Frame touch monitors have high specifications, full-featured, easy to use features, suitable for different environment, including heavy industry, automation, medicine, aviation, transportation, and commerce....etc. AMT touch screen solutions conform to many testing standards and satisfy customers’ high diversity needs. AMT understands the issues facing product applications in different industries, and this understanding lets us customize touch products for our customers. Here to share with you our recent success stories.
The end customer, in this case, is INOMED, one of the leading manufacturers of medical equipment in surgical rooms. Due to the unique needs of medical applications, INOMED and SCHURTER tested and qualified the products from AMT for over a year and confirmed that our products meet the medical safety test standards. SCHURTER designed in and integrated our standard projected capacitive (PCAP) touch panel and PenMount touch controller for their C2 Xplore, which monitors nerves during thyroid surgery to ensure the laryngeal nerves are unaffected during the operation. This story is about how AMT provides satisfying support and how we will tackle unforeseen challenges to serve our clients.
Before distributing the products, all the devices meet the medical standards required. However, after six months, 5-10% of the devices were affected by an unknown source. Identifying the sources, adapting the firmware to avoid interferences, and updating the firmware became the challenge of AMT.
Specialists from AMT first help the end-user identify the source of interference. It turns out there were interference signals generated by electric surgical knives and lights in the operation room. We further advised them to measure the frequency range of the signals and set out to resolve the issue after receiving the data. After adjusting the firmware parameters such as median filter, spike filter, and extended frequency hopping through PenMount PCIUtility, and successfully adapted the working frequency to bypass the local interference!
The second challenge surfaced as AMT provided the solution. To update the firmware, utility needs to be installed. How could the distributor update the firmware with the least time and man power? The client again sought help from AMT. We worked on the update and package the firmware using a command line to make the update pain-free. If the hospital is equipped with wireless signal, they could even update the firmware easily though internet.
This story showcases the unparalleled effort AMT to support our clients. We all know that it doesn’t matter how thorough we are with product design; there are bound to be unforeseen issues due to the working environment of the devices. The salespeople from AMT are always there to help our clients make customized adaptations to resolve these issues.
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.
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.
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!
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!
이 경우 고객은 중소형 LCD 터치 모듈 개발 및 제조를 전문으로 하는 업체입니다. 그들은 TFT, OLED 및 LCM 모듈을 생산하지만 타사 공급 업체로부터 터치 스크린 및 광학 본딩 서비스를 인수했습니다.
이 프로젝트의 경우 클라이언트는 매우 구체적인 요구 사항을 가지고 있었습니다. 원래 공급업체는 특수 설계, 소량 또는 기술 수정을 수락할 수 없었습니다. 고객은 원래 공급업체가 설계를 사용자 정의하지 않는다는 것을 알게 된 후 AMT에 연락하여 문제를 해결할 수 있기를 희망했습니다. 저희 판매원은 요청을 받은 후 즉시 전화로 연락을 주셨습니다. 그들은 애로점을 식별하고 원래 설계의 문제를 분석했습니다. 그런 다음 그들은 고객의 요구를 충족시키는 최상의 솔루션을 제공하기 위한 혁신적인 계획을 개발했습니다.
이 경우의 문제는 산업용 플라스틱 프레임의 제품 깊이였습니다. 프레임의 디자인과 깊이 때문에 롤러를 접착에 사용할 수 없습니다. 또한 대부분의 플라스틱 프레임은 빛을 흡수하는 검정색입니다. 따라서 UV는 LOCA 또는 "광학적으로 투명한 액체 접착제"를 경화하는 데 사용할 수 없습니다.
AMT에서 생산하는 Lucent Gel SOCA 또는 "고체 광학 투명 접착제"는 이러한 유형의 제품에 가장 적합한 솔루션입니다. Lucent Gel은 실리콘 기반으로 부드럽고 유연하며 소포(debubble) 성능이 좋습니다. 특수 결합 고정 장치와 결합되어 모든 깊이에서 플라스틱 프레임의 광학 결합에 적합합니다. 마지막으로 제조과정에서 문제가 생기면 루슨트젤이 LOCA보다 reworkability가 훨씬 뛰어납니다.
클라이언트는 AMT의 전문 기술을 믿고 즉시 프로토 타입을 우리에게 보냈습니다. AMT는 샘플 제품을 받은 후 일주일 이내에 고객의 고유한 요구 사항을 충족하는 프로토타입 생산을 시작할 수 있었습니다. 우리는 우리의 전문적인 능력을 자랑스럽게 생각하며 항상 기꺼이 고객을 도울 준비가 되어 있습니다.
