Hello,
we intend to use CFAG320240CX-TMI-T displays in our sun simulators. Each time the xenon discharge lamp is ignited, there is a quite big EMI pulse that freezes the display. Can perhaps anybody tell me how to archive the optimal grounding set-up for a maximum EMI/ESD protection? The Display is mounted directly on top of the µc-PCB with a multipoint connector (no ribon cable is used), and the complete set-up is in a closed metal box. Should the jumpers JF1 (mounting holes to the bezel’s grounding tabs) and/or JF2 (signal ground to the bezel’s grounding tabs) better be closed or left open? Should the Frame Ground (PIN 18 FGND) be connected to the chassis ground or the signal ground (PIN 1) or left disconnected?
Thank you so much for any help and/or recommendations!
