2.3-inch Red Alphanumeric LED Displays

Big, ultrabright and beautiful 17-segment alphanumeric displays with red segments and 2.3" character height! These are the same displays we use in the Alpha Clock Five, Red Edition.

The segments light up in ultrabright red. Also available in ultrabright white and ultrabright blue.

These are seriously bright when driven at full current, and can be placed behind a darkened window for even higher contrast viewing. A total of 54 LED elements are inside the matrix to drive the segments and dual decimal points.

The internal wiring configuration is common anode. The decimal points contain a single LED element. The six "short" segments each contain two LED elements in series. The ten "long" segments each contain two LED elements in series, twice in parallel. To drive the display, we recommend using two constant-current LED driver ICs, one of which is configured for roughly 25 mA (for the six short segments and decimal), and one of which is configured for roughly 50 mA (for the long segments).
