Irvine, Calif. BivarOpto, the Optoelectronics division of Bivar Inc., has added a new ultra-high reliability blue seven-segment display to its BD series for applications that require highly reliable performance in mission-critical applications such as medical and life support systems, avionics, and industrial controls. These new devices also tout color enhancements that improve accurate visual perception and attention.
The new BD Blue series is available in a range of single-digit, seven-segment LED displays, ranging in five different digit heights from 0.301 in. (7.7 mm) to 1.0 in. (25.4 mm), in 24 different styles and models. Available in either common anode or common cathode circuitry, these displays may be used in any numeric display configuration, including right- and left-hand decimal. Featuring a specially compounded diffused lens for even color distribution, the standard wavelength is 465 nm (peak). The standard face color is black with white-diffused segments. Other segment or face colors are available by special order.
The company said each segment of the 1.0-inch, seven-segment display features two chips in series that results in the industry's highest uniformity and tight bin control processes for greater brightness and color. These displays use Cree Technology-based dice, the same high-efficiency InGaN chips as used in BivarOpto's discrete and surface-mounted LED products, a geometrically enhanced design to maximize light extraction efficiency while operating at low current.
"The redundant dual-chip design in each segment assures reliable performance and uniform light distribution, while the chip's inherent strengths creates enhanced brightness at this wavelength which supports recent market interest in blue indicators and displays," stated Anthony Vilgiate, Bivar's vice president, strategic business development.
The new displays are manufactured in compliance with the EU's Restriction of certain Hazardous Substances (RoHS) and Waste Electrical and Electronic Equipment (WEEE) materials and process specifications.
The displays are priced at less than $ 4.00 per digit in production piece quantities. Standard ESD-packaged units are available from stock. Custom options in color or characteristics are available by special quotation.
