Original Press Release:

New Optrex F-51553 Series 128 x 64 LCDs Offer Wide Operating Temperature and Serial Interface Option

Plymouth, MI, February 2003 - Optrex America's new F-51553 series of 128 x 64 dot COG (chip-on-glass) monochrome STN transmissive LCD modules feature a 2.8" diagonal area that can display text and graphics together, providing an economical step up from straight character displays for applications requiring an integrated text/graphics messaging solution.

The new F-51553 modules provide a wider temperature range (-20°C to +70°C) than Optrex's popular F-51320 Series COG monochrome LCDs. They also provide greater temperature stability (though use of a liquid crystal fluid with a flat voltage vs. operation temperature characteristic to enable operation over the entire temperature range without the need for voltage adjustment). The F-51553 supports serial as well as parallel interface, allowing designers the option of specifying their desired interface type.

The Blue Mode version (P/N F-51553GNBJ-LW-AB) displays white characters or graphics on a blue background, features a highly efficient 3-chip white LED backlight, and offers a contrast ratio of 6:1.

The Blue Mode F-51553 LCD has a total power consumption of only 0.385W max. because of the higher efficiency white LEDs used in its construction. This reduces the problem of heat dissipation for components where that is a particularly sensitive issue, such as servers or hand-held monitoring instruments.

Optrex also offers a Yellow Mode version of the F-51553 series (P/N F-51553GNYJ-LY-AA), with a black display on a yellow-green background. It incorporates a 28-chip yellow LED backlight, and offers a contrast ratio of 4.5:1. Its total power consumption is 1.35W max.

Both LCDs' high level of component integration saves valuable design, sourcing and set-up time. Unlike other COG LCDs, they incorporate a backlight as well as mounting features. Controller, row and column drivers and a booster circuit are incorporated into a single chip. The use of the on-board voltage booster circuit ensures the proper voltage for driving the LCD panel without the use of an external DC-DC converter.

In addition, Optrex, the LCD Total Solution Provider, provides full U.S. engineering support for the F-51553 Series, as well as easily accessible application notes and links to controller manuals on its web site --

Pricing for the Blue Mode F-51553 Series LCD (P/N F-51553CNBJ-LW-AB) is $16.64 each in 1,000-piece quantities. Pricing for the Yellow Mode unit (P/N F-51553CNYJ-LY-AA) is $14.79 each in 1,000-piece quantities. For additional pricing details, contact Optrex America.
