Do you have a “ruggedized” display module?
This is not our core competency. We suggest that you look at products from Beijer Electronics which are designed for rugged applications.
What is your IP rating?
Although the gaskets used in our enclosed units provide an effective waterproof seal and dustproof seal, they currently do not have a NEMA or IP rating. For more details, visit mounting options.
Are your products CE Certified?
Our enclosed units have passed the EMC and EMI requirements of the CE certification. All our boards are RoHS-2 compliant using a lead-free solder assembly process. Metalwork is also RoHS-2 compliant (see RoHS-2 details). We are assembling the technical file needed for self CE certification. Please feel free to contact us regarding this or for a copy of the EMC/EMI test report.
Have you done EMC testing on your enclosed units?
We have tested the 5.7″ Standard Enclosed Unit. It successfully passed the EMC tests. For detailed information, please see the test report.
Do you have any design suggestions for enhancing ESD immunity?
To provide added ESD protection to the SLCD43 display modules, we use 3M 1170 conductive tape to connect the metal frame of the LCD panel to the digital ground (equals ESD or chassis ground) on the SLCD43 controller board. The controller board has grounded mounting holes that need a solid connection to chassis/Earth/ ESD ground. This approach provides approximately 4KV ESD protection. However, from a regulatory point of view, ESD testing has to be done with the display module in the customer’s enclosure with a system ground. If you are trying for high ESD immunity, the bezel “should” be metal or metalized plastic, although it may be OK with just plain plastic. Our suggestions are: If using a plastic bezel, add a metalization coating to the plastic bezel, and ensure good contact between it and the front panel. Use a flexible conductive gasket to ground the metal frame of the [...]
Do you have EMC/EMI test reports or CE Self-Certifications?
We have not done a full EMC/EMI report since modules are not finished products. Likewise, self CE certification has to be done on a finished product, and our modules are sub-assemblies. We have had many customers pass CE and FCC testing with varying enclosures. We do have an EMC “prescan” of the SLCD43 (currently shipping model, 40 pin 400 nit) with an FCC Class A limit line taken while the display was showing a “checkerboard” pattern, which is the worst case for display EMI. We use a spread spectrum oscillator for the display, which helps spread emissions. See the report.
Do you have any suggestions for reducing EMI emissions?
If there are problems with EMI emissions on the 5.7″ or 7″ modules, you can try using a ferrite core on the flat flex cable.
Are touch panels usable in wet conditions? Wet fingers? Wet screen?
Touch panels are not rated for continuous water exposure, mostly for aesthetic reasons (e.g., dried water leaves mineral spots on the screens). Also, it would be best to seal the screen to the bezel since water cannot be allowed to get on the edge of the panel. You can make it waterproof by using a thin (10 mil / 0.010″) clear polycarbonate layer on top. Maverick Label can make these and add a back-printed border, so you only see the active panel area. See also “Silicon Foam Gaskets” in Mounting Options.
Do you have any spill resistant, waterproof or dust-proof displays?
Spill resistance is a function of the case, not the display. The gaskets in our enclosed units provide an effective waterproof seal and dustproof seal, but only when mounted in a suitable enclosure. While our Enclosed Units currently do not have NEMA or IP ratings, we have several customers using these units in dusty and wet environments. Search for "enclosed" on this site for more information.
Do you have any sunlight or daylight-readable displays?
We have some high-brightness options, but brightness alone does not make a screen sunlight/daylight readable. Some of our customers use a shroud to shade the screen. We do have the capability of creating an outdoor-readable screen if we have a lead customer to justify the investment. See custom modules for more information.
