Do you have tips on getting UL, CSA or ETL approval?

You may want to get UL, CSA, or ETL approval for your product that incorporates a Reach display controller or module. One question that the agency may ask is the flammability rating of the screen which is pertinent only to displays that use high voltage CCFL (Cold Cathode Fluorescent Lamp) backlighting as voltages above the ELV (or SELV) limit are present for these backlights. Voltages that do not exceed the ELV limit drive LED backlights and thus the flammability of the display typically does not need to be considered. While this is not an exhaustive explanation of the issue, it helps direct those uninitiated into the intricacies of the rating agency requirements. If you are applying for UL certification and your product contains a Reach product, please contact Reach Technical Support for materials that the UL certification body requires.
