I have been collecting which types of flat ap. grill are which:
Sony (Triniton FD) licences to KDS for use in the AV series, ADI G and F series, CTX Professional series, IBM P series, Artmedia FD Trinitron/A series, and Mag Graphics series.
The other is Mitsubishi (Diamondtron NF), which licences to the Viewsonic PF series, NEC Diamond Plus (and some Pros), Iiyana VisionMaster Pro series, Samsung SyncMaster NF series, Acer P series, Dell P series, and their own Diamondpro series.
