| LD-701 Series LED displays Large flat displays LD-701 Series The LD-701 series were designed in response to the need for large, flat displays. These are three-chip, flat displays with high luminance. !External dimensions (Units : mm) 21.0 19.80.1 4.50.1 5.7 2 Pin No.1 23 45 0.6 Pin No.1 2 (7.0) 34 56 (2.5) (7.0) 5.00.5 !Features 1) Three independent chip elements. 2) Large 4.5 x 19.8 mm emission area. 3) Thin outer casing, multiple units can be coupled together. 4) Four colors are available: red, orange, yellow and green. 5.60.1 0.3 6 Tolerances are 0.3 unless otherwise noted: !Selection guide Emitting color Type Order-based production.
