Graphic VFD

The display is expensive but it maintains the look of the instrument whilst adding a new dimension. The Noritake display is a full graphic module that represents the latest VFD technology and enhances the instrument and uses the same reliable and optical base technology as the original design.

There are a number of variants of display available from Noritake. The one chosen is the GU280x16G-7806A and has the extended font set. This version was chosen for very fast plotting of large fonts but also contains a miniature font for labelling screen sections and a 5×7 font for tone numbers on the patch selection display. All other fonts are generated by the microcontroller on the Display PCB and bitmaps are sent to the GU280. Other graphic GU280 display types will not work as they have a non-standard interface.

The display with European fonts is required and is denoted by “A” in the part number. There are other part numbers similar (e.g. GU280x16-7000G, GU280x16-7003G) but they will not work as they do not support the fonts or connection method required.

The GU280x16G-7806A VFD glass is made in Japan and the module has been designed and manufactured in the UK. This particular module is pretty special, it can also emulate standard LCD character displays by responding to the same protocol. Therefore, it can replace a standard 40×2 LCD provided that there is enough power available.
