Dimensions: 15.5*4*4.6CM [Retro] Born in Japan in 1966 VFD (fluorescent display tube) is a technology that was first developed in the world in 1966 by Ise Electronics Co., Ltd. in Japan. Like Nixie tubes, VFDs were adopted as displays during the calculator wars and became widespread throughout the world. [Beautiful Vacuum Condition] When the filament (cathode) is heated to around 600 degrees in a vacuum glass tube, electrons are released. Electrons are attracted to the positive potential of the anode and emit light when they collide with the phosphor on the anode. Based on this principle, numbers and letters are displayed by switching the positive and negative sides of the anode. [Luxury Feel] Compared to LEDs, VFD light has a softer and more luxurious feel. The mechanism that can be seen inside the vacuum tube and the futuristic appearance of the blue-white light are the big attractions of VFD. *Function*: Time synchronization via Wi-Fi, remote control operation, temperature and humidity display, timing switch, alarm function, timing brightness adjustment, light color adjustment, and stopwatch function. VFD Modular Clock is a clock based on an old-fashioned fluorescent display tube. The VFD display color is green or blue and emits a bright light with high contrast.
