In 1972, Hewlett-Packard introduced the 5082-7415, a 5-digit numeric LED display for use in their first generation of handheld calculators. HP later manufactured other variants of this display with two, three or four digits. These devices are pin-compatible with the Litronix DL330 and other similar displays. Devices in this series are not intelligent; control must be provided entirely with external drive circuitry.
