The Noritake Itron / ISE Electronics CU40026SCPB-T20A is a 40-character by 2-line Vacuum Fluorescent Display (VFD) module with 5×7 dot matrix character rendering. The display delivers 700 cd/m² typical luminance in blue-green, with optical filter compatibility for alternative colors including blue, green, yellow, white, purple, and red. Fully integrated VFD glass, driver and micro-controller ICs support refresh RAM, character generator, and interface logic for direct embedded system integration.
