All Products
| Reliability Testing | Customers can expect all production parts to meet or exceed operational requirements over temperature, humidity, and vibration. |
| Glass Cleanliness | Customers can expect glass to be protected by liners and presented mindful of cleanliness standards. This means glass will be clean of contaminants, fingerprints, and other foreign material. |
| Bezel Appearance | Bezels will be uniformly painted free of foreign materials and distracting cosmetic blemishes. Our standards maintain a clean scratch-free surface. |
| PCB Appearance | PCB’s are delivered with long-term reliability in mind. Finishes are free of bubbles, foreign contaminants, and meet all UL fire requirements. PCB materials will always be delivered within industry norms. PCB edges will be cleanly cut and void of burrs. |
| Soldering | Soldering of all leaded and SMT components is consistent in providing the mechanical security and electrical connectivity. |
| Consistency | Our manufacturing and inspection processes ensure product consistency from lot to lot. This means orders processed over the years will continually meet your expectations. We do this by exacting manufacturing specifications, with attention to detail in our processes, and by comparing to the golden units. |
| Product Integrity | Quality in product manufacturing ensures integrity in construction. Customers can expect tight assembly without worry of loose parts or missing material. Our products will meet all environmental expectations including temp, humidity, & vibration conditions. |
| Glass Color | While normal variations of glass color may occur (due to manufacturing tolerances), Newhaven Display maintains color compliance per internal approved color charts. These charts are maintained to ensure any minor glass deviations are identified and corrected as needed. |
| ESD Protection & Safety | All devices are designed and handled in consideration of ESD protection. This includes ESD-SAFE packaging within anti-static bags, wraps, and trays. Customers are reminded to always follow ESD safety to best protect the devices. |
Available in character and graphic formats, COG (Chip-On-Glass) LCD Displays are designed without a PCB. The LCD driver/controller is bonded directly to the glass of the display. This allows COG displays to be smaller in size, more cost effective and a highly customizable display solution compared to typical LCD modules with a board.
Adjust the length, position, and pinout of your cables or add additional connectors. Get a cable solution that’s precisely designed to make your connections streamlined and secure.
Easily modify any connectors on your display to meet your application’s requirements. Our engineers are able to perform soldering for pin headers, boxed headers, right angle headers, and any other connectors your display may require.
Choose from a wide selection of interface options or talk to our experts to select the best one for your project. We can incorporate HDMI, USB, SPI, VGA and more into your display to achieve your design goals.
Choose from a wide selection of changes including shape, size, pinout, and component layout of your PCB to make it a perfect fit for your application.
