Plymouth, Mich. A new family of high-legibility monochrome graphic and character LCDs from Optrex America offers designers display solutions in a range of color options and in six industry-standard configurations.
The new LCDs offer a combination of performance enhancements that include a uniform, high-contrast black background for improved legibility, a variety of display colors, wide operating temperatures, industry standard configurations, compatibility with existing Optrex modules, and RoHS compliance. Applications include consumer audio (such as MP3 players), industrial test and process control equipment, computer peripherals, industrial panel meters and data collection displays, high-end white goods, and medical instrumentation.
Optrex's new high-legibility graphic and character LCDs utilize the company's high performance partial color technology, which incorporates a high-contrast negative mode panel using an internal black mask and color LED black light to provide a uniform, high-contrast black background for easier viewing. Colors available include white, yellow, green and blue. They are mechanically and electrically compatible to Optrex's existing monochrome character and graphic LCDs to provide an easy upward migration path for designers.
The company said the modules use a flat liquid crystal (LC) fluid for minimal voltage change over the operating temperature range, allowing them to support 5-V operation over the temperature range of -20°C to 70°C without the need for a temperature compensation circuit.
The new LCD family includes a series of graphic and character modules in six industry standard configurations. The F-51852 series offers 2.8-inch diagonal modules with a 128 x 64-dot pixel resolution for display of characters and/or graphics in white, blue, green or yellow. Mechanically compatible with Optrex's existing F-51553 series, the new modules offer a selectable 8-bit serial or parallel interface and a built-in controller. (The F-51852GNFQH-LW-AFN graphic module offers an extra-wide operating temperature range of -30°C to 80°C.)
The new F-51851 series of 5.2-inch diagonal monochrome graphic LCDs feature a 240 x 64-dot pixel resolution with 8-bit parallel interface and built-in controller. They are mechanically compatible with Optrex's existing F-51405 series.
New high-legibility monochrome character LCDs include the C-51847 series, which features a white, blue or green 20 character x 4-line display and is mechanically and electrically compatible with Optrex's DMC-20481 series. The C-51848 series modules offer a white, blue or green 16 x 2 display and are compatible with Optrex's DMC-16230 series. The C-51849 series modules have a white, blue or green 40 x 4 display and are compatible with Optrex's DMC-40457 series; and the new C-51850 series LCDs feature a 40 x 2 display in white, blue or green and are compatible with Optrex's DMC-40202 series. Additional colors are also available.
All of the new modules are "green" products, with complete compliance to the European Union's RoHS (Reduction of Hazardous Substances) directive that restricts the use of certain hazardous substances such as lead, mercury and cadmium in electrical and electronic equipment by July 2006.
Pricing for Optrex's new F-51852 series 2.8-inch diagonal high legibility graphics modules starts at $19.07 in OEM quantities.
