Fluorescent displays are manufactured by lamination of at least one film A containing a polyvinyl acetal PA and, optionally, a plasticizer WA and at least one film B containing a polyvinyl acetal PB and at least one plasticizer WB between two glass panes, wherein prior to lamination, film A contains less than 22 wt. The system and method incorporate a seed dispensing tube configured to dispense seeds, a granule tube configured to dispense chemical, an electrical valve configured to open so that chemical granules may be dispensed from the chemical granule tube, and a proximity sensor operably coupled to the electrical valve, the sensor being configured to sense a seed dispensed from the seed dispensing tube. The porous layer and the fire-retardant layers are coupled together. During this first spacer etch, the photosensor region is covered with resist.
