external dimensions (units: mm) 172 led displays high efficiency, single-digit numeric displays la-301 bl series the la-301 bl series were designed to meet the need for 8 mm single-digit nu- meric displays. these led numeric dis- plays use gaasp on gap for the emit- ting material (with the exception of green) and are housed in an epoxy res- in package. they are single-digit dis- plays with a character height of 8 mm. features 1) large display with small exterior di- mensions. 2) compact package with little worri- some light leakage from segment. 3) red, orange, yellow, and green are available in common anode and common cathode configurations. 4) the package surface is painted black and the segments are colored the display color. selection guide pin assignments, bl series
