With a loose scrap of conductor shorting one of the cathodes inside the tube, the damaged VFD isn’t much to look at, and is beyond reasonable repair, but it’s kind of cool to examine the spring mechanisms that take up slack as the cathodes heat up and expand. does a lot of fiddling with the stock filters to change the look of his VFDs, some to good effect, others less so.Īs for the internals of VFDs, ’s look at a damaged display reveals a lot about how they work. But put a pink filter between the display and the world, and suddenly those turquoise phosphors look white. It turns out, the phosphors used in those displays weren’t white, but closer to the blue-green color that VFDs are often associated with. But the teardowns do provide some insights into how VFDs work, as well as suggest ways to tweak the overall look of a VFD.įor example, consider the classy white VFDs that graced a lot of home audio gear back in the day. In some ways, the video is just a love letter to the VFD, and that’s just fine with us. Give us the chunky, blocky goodness of a vacuum fluorescent display (VFD) any day of the week for visual interest and retro appeal.įrom the video below, it seems like certainly is in the VFD fandom too, rolling out as he does example after example of unique and complicated displays, mostly from audio equipment that had its heyday in the 1990s. ![]() If you can determine the pinout of the display it may be possible to make something to drive a LED display, but practically, 100 is unlikely to cover your costs unless you make. As expected theyre a high voltage, low current driver. It’s a bit boring when the front panel of your widget is the same thing you stare at hour after hour while using your phone. Ive had a quick look at the drivers used for these displays. ![]() VFD needs thick, strong sealing glasses for vacuum encapsulation which makes the VFD very thick.īelow is an example of COB structure 16x2 character modules of OLED, STN-LCD and VFD comparison on thickness.Everyone knows we’re big fans of displays that differ from the plain old flat-panel LCDs that seem to adorn most devices these days. VFD display is self-luminous as well, but VFD needs the mechanical parts mounted around the display frame. OLED layers are applied directly to the surface of the glass substrate and this allows the display area to be extended to the edge of the glass substrate, which requires no backlight and make the displays very thin. Some STN LCD modules could be workable at lower temperature or with heater on LCD module, but the response time at lower temperature will be longer than normal temperature since the liquid crystal has been frozen.Ī significant advantage of OLED displays over traditional liquid crystal displays (LCDs) is that OLEDs do not require a backlight to function, OLED is self emitting. It is very obvious especially at lower operation temperature the OLED display works excellent. The nature of OLED technology is self-luminous the OLED displays still can work at rugged environment. Comparing with conventional STN LCD displays, OLEDs featured with wider operation temperature range -40 ℃ ~ 80 ℃.
