Montage of images from RCA's May 1968 press conference announcing the creation of the first LCDs. Top: George Heilmeier demonstrates a numeric counter with a dynamic scattering liquid crystal display. Bottom Left: Joseph Castellano uses a pair of electronic shutters to demonstrate how liquid crystals can modulate the passage of light. Bottom Right: Robert Lohman compares his analog wristwatch with the world's first clock with an LCD readout.

Happy #LCD Day! #OnThisDay in 1968, #RCA announced the invention of a new type of electronic display that used #LiquidCrystals to modulate light.
