Monochrome Display Modules provide high contrast ratio.

Press Release Summary:

Series C-51505 20 character x 2 line displays employ negative mode panels with company's High Performance Color technology, contrast ratio up to 80:1, and 15 mA operating current. Backward-compatible to existing industry standard displays, they use flat, LC (liquid crystal) fluid to support 5V operation over -20 to +70° C temperature range. Negative mode versions are offered in white, green, and blue characters on black background; positive version are also available.

Optrex Introduces Improved Performance Alternative to Industry Standard Character Displays

Plymouth, MI, November 2002 - The new C-51505 Series of 20 character x 2 line monochrome displays offers improved performance in an industry standard configuration and a striking appearance that allows design engineers to differentiate their products, all at a cost similar to standard LCDs.

Performance improvements provided by the C-51505 Series include better legibility via a negative mode panel using Optrex's proprietary High Performance Color technology, wider operating temperature range (-20° to +70°C), higher contrast ratio (up to 80:1), lower operating current (15mA) and a four-fold increase in luminance when compared to industry standard character displays.

C-51505 modules are backward-compatible to existing industry standard displays such as Optrex's DMC-20261 Series, but with a higher contrast ratio, wider operating temperature range, lower operating current, and higher luminance - all at a minimal cost differential. The use of the latest advancements in LED backlighting technology in the C-51505 Series permit a single chip to provide higher luminance with a substantially lower current draw (15mA compared with 130mA on displays like the DMC-20261).

Employment of a flat LC (liquid crystal) fluid permits the C-51505 modules to support 5V operation over the entire -20° to +70° C temperature range without the use of a temperature compensation circuit.

C-51505 modules present the design engineer with a range of colors from which to choose. The negative mode versions (C-51505NFQJ-LW-AD, C-51505NFQJ-LG-AF and C-51505NFQJ-LB-AE) offer white, green or blue characters on a black background. There are also several positive mode versions available with different colors on lighter backgrounds.

The compact C-51505 Series modules measure 116.0 mm (W) x 37.0 mm (H) x 15.6 mm (D), with a viewing area of 83 mm (W) x 128.6 mm (H) and a maximum weight of 42.9 grams.

Pricing for C-51505 Series monochrome character LCDs starts at $18.70 for P/N C-51505NFQJ-LG-AF in production quantities. For additional details, contact Optrex America.
