HDSP-550x, HDSP-552x, HDSP-560x, HDSP-562x, HDSP-570x, HDSP-572x, HDSP-H15x, Series 14.2 mm (0.56 inch) Seven Segment Displays
Data Sheet
Description
The 14.2 mm (0.56 inch) LED seven segment displays are designed for viewing distances up to 7 metres (23 feet). These devices use an industry standard size package and pinout. Both the numeric and ±1 overflow devices feature a right hand decimal point. All devices are available as either common anode or common cathode.
Applications
These displays are ideal for most applications. Pin for pin equivalent displays are also available in a low current design. The low current displays are ideal for portable applications. For additional information see the Low Current Seven Segment Displays data sheet.

Note:
1. These displays are recommended for high ambient light operation. Please refer to the HDSP-H10X/K12X AlGaAs and HDSP-555X HER data sheet
for low current operation.
Contrast Enhancement
The objective of contrast enhancement is to provide good display readability in the end use ambient light. The concept is to employ both luminance and chrominance contrast techniques to enhance the readability. This is accomp lished by having the OFF dots blend into the display background and the ON dots stand out vividly against this same background. Therefore, these display devices are assembled with a gray package and matching encapsulating epoxy in the dots.
Contrast enhancement may be achieved by using one of the following suggested filters: Standard Red and AlGaAs Red (HDSP-5300/H150) Panelgraphic RUBY RED 60 SGL-Homalite H100-1605 RED 3M Louvered Filter R6610 RED or N0210 GRAY HER (HDSP-5500) Panelgraphic SCARLET RED 60 SGL-Homalite H100-1670 RED or H100-1250 GRAY 3M Louvered Filter R6610 RED or N0210 GRAY
Mechanical
Specially developed plastics are used to optimize the displays optical performance. These plastics restrict the solvents that may be used for cleaning. Only mixtures of Freon (F113) and alcohol should be used for vapor cleaning processes. Total immersion time in the vapors is two minutes. Some suggested mixtures are Freon TE, Arklone A or K, or Genesolv DI-15 or DE-15. A 60°C (140°F) water cleaning process may also be used. This process includes a neutralizer rinse (3% ammonia solution or equivalent), a surfactant rinse (1% detergent solution or equivalent), a water rinse, and a thorough air dry. Room temperature cleaning may be done with Freon T-E35 or T-P35, Ethanol, Isopropanol, or water with a mild detergent.
Cleaning agents from the ketone family (acetone, methyl ethyl ketone, etc.) and from the chlorinated hydrocarbon family (methylene chloride, trichloroethylene, carbon tetrachloride, etc.) are not recommended for cleaning LED parts. All of these various solvents attack or dissolve the encapsulating epoxies used to form the package of plastic LED parts.
