Similar to a cathode ray tube but using a different operating principle, a VFD uses cathodoluminescence and operates at significantly lower voltages.
Anodes in each tube of a VFD are covered with phosphor and subjected to bombardment from electrons released from the cathode filament.
The cathode filaments, anodes (phosphor), and grids make up the three fundamental electrodes of the VFD, which are housed in a glass enclosure and operated under high vacuum.
The alkaline earth metal oxides that are deposited on the thin tungsten wires that make up the cathode produce electrons.
The Global Vacuum Fluorescent Display market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The Vacuum Fluorescent Display glass, driver and microcontroller ICs with refresh RAM, character generator, and interface logic are all included in the Noritake module CU16025-UW6J.
The host CPU bus can be connected to the high-speed 8-bit parallel interface using a 5V CMOS compatible chip that is configured to the M68 or i80 series interface through a solder link on the module. There are functions for power reduction and brightness control.
A vacuum fluorescent display glass, VF drivers, and microcontroller ICs with refresh RAM, character generators, and interface logic are all included in the module GU128x64D-7000, a dot graphic VFD module.
The 5V TTL/CMOS compatible high speed 8 bit parallel interface is appropriate for connecting to a host CPU bus.
The asynchronous serial interface supports parity-free baud speeds up to 115,200. Without initialization directives, the module is prepared to accept ASCII characters.
