A few of my vintage LCDs and LEDs , definitely not all of them .
Some Texas Instruments , National Semiconductor , Sensor , Phasars .
Some Bulova , Phasar , Casio , and miscellaneous .
These are all made by National Semiconductor . A few are branded differently , a couple under the Phasar branding and one Elektra that I've never seen another like it .
A few Speidel and Sensor and some chunky ones of different brands .
Some vintage LED watches of different brands all working .
