optrex has introduced the F-51136 NCWHU-FW-AA-4.2 STN 256 × 64 LCD, a full color RGB transmissive graphic display offering a wide viewing angle. It features a cold-cathode fluorescent (CCFL) backlight with a 25,000 hour (typical) lifetime to half brightness point. An on-board, 12 V heater and integrated temperature compensation circuit enable a wide operating temperature range of – 30 ° C to 85 ° C. Optrex double cell STN color technology ensures storage temperatures of – 40 ° C to 90 ° C and provides a contrast ratio of 70:1. The on-board heater and integrated temperature compensation circuit maintain optimum contrast across the operating temperature range. The Optrex F-51136 LCD meets application requirements in demanding operating environments.

The F-51136 STN LCD module is engineered with an on-board controller and a DC-DC converter to regulate driving voltage for proper display contrast. The single CCFL backlight provides high brightness levels (to 150 cd/m2 brightness typical) for viewing ability in either normal or low-light conditions. The outline dimensions are 146.2 39.9 × 17.0 mm with a viewing area of 106.66 × 27.62 mm. Dot pitch is 0.135 mm (W) × 0.385 (H) — the 0.135 mm (W) is per red, green, or blue sub pixel.

F-51136 features include data transfer 8-bit parallel, SED1353F1A controller IC onboard, 256K SRAM onboard, low voltage operation, low power consumption, light weight, and compact design. The LCD also provides both graphic figure and character display capabilities.
