WHAT'S VFD MODULE
A VFD module incorporates a controller, anode driver, grid driver and power supply circuit to make evaluation easy.
Perform a variety of display control functions using a simple command. Multiple interface options are available.
To accomodate customer specifications, we can do special orders for interface and software.
The CU-U series displays are all built with LCD compatible dimensions and HD44780 command sets. These displays are easy to read due to high contrast, have wide viewing angles and are easier to read at short and long distances. Additionally, VFD displays have a quick display response within the module’s temperature range of -40C to +85C. Noritake offers long term supply and engineering support with their products.
Vacuum Fluorescent Display provides filaments that create electron density. Filaments function as a Warm Electrode. When subjected to heat by an electric current, filaments produce electrons.It also contains (luminescence) cathodes, which are employed form the digits and letters.
Thin metal grids encompass the anodes, trying to control the dissemination of electron density from the filaments to the anodes.
Whenever the charged particles transmitted by the filaments attack the luminescence, it lights up.
A vacuum fluorescent display, compared to a liquid crystal display, transmits extremely strong light with contrast ratio and also can assistance display components of various color combinations. VFD illumination statistics seem to be typically around 640 cd/m2, with high-brightness VFDs functioning at 4,000 cd/m2 and investigational modules achieving as high as 35,000 cd/m2 based mostly on drive voltage and timeframe.
