Product Description

This is the last stock, they're all gone once we sell out. Price is for one display module!

This is the classic HP QDSP-6064 bubble display, a tiny, 4-digit, 7-segment numerical indicator. This little guy is perfect if you need some user feedback from your system, but don’t want to fiddle with LCDs or other display options.

The Bubble Display comes in an easy-to-use 12-pin DIP package and can be used in breadboards, protoboards, or PCBs. Used in calculators and watches from the 1970s, they're great for retro projects or just tiny number displays. 

These bubble displays have a peak forward current per segment of 5mA at a peak forward voltage of 2V. Thanks to a neat magnification technique used by the QDSP-6064 (giving it the “bubble” name), the luminosity is intensified making lower power consumption possible.

Please take note of the forward current specifications - only 5 mA per segment!


  • Forward Voltage: 1.6-2.0V per segment
  • Forward Current: 5mA per segment
  • Peak Wavelength: 655nm
