Do you offer an analog VGA interface?
You would be better served using one of the following vendors to get an LCD controller with an analog VGA interface: Digital View: Look in the Products, LCD Controllers section. Spectrah Dynamics
Do you offer multi-touch screens?
We do not offer any displays with multi-touch. Our GUI items do not include any elements that can use multi-touch.
How does your solution compare with Maple Systems?
Maple Systems touch screens are highly feature-rich regarding speed and connectivity; hence, they’re more complicated to use (and more costly). If you don’t need 3D animations, the ability to play video or music, or Ethernet connectivity, you will find our SLCD solution more than adequate and much simpler to use. If you need some of those features, check out our G2 display modules. Since our SLCD interface to your system is a Command Line Interface implemented over a serial port, any UART microcontroller with enough speed and memory to handle your application will do just fine. If you want to discuss your application requirements and which of our products will best meet your needs, please contact our technical support team. Note: If you do need 3D animations, video, or Ethernet, be sure to look at our G2/G3 modules, which use an industry-standard IDE (Qt Creator), programming language (QML), and operating [...]
Are your controller boards able to control devices other than the display in the outside world?
Our controller boards communicate with other devices via the “aout” command, which can send ASCII text out to any serial port on the display controller. SLCD boards do not have any GPIO for signal control (this is available on G2C1 and G2H2 modules). Please let Reach Technology Technical Support know if you have any other concepts of “control.”
Do you offer any small display units?
We specialize in displays for medical and industrial applications and only support LCD form factors that are “industry standard,” which means they will be available for 5-7 years or longer. The smaller displays (under 4.3″) tend to be device-specific and therefore change every 18 months. Suppose you’re not already aware of the vagaries of the LCD market and especially of the availability of LCD products. In that case, you might want to read, “The LCD business is very different from others.”
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.
