Description

WO1602N model is a COG structure VATN LCD module made of 16-characters by 2-lines with VA Negative Transmissive LCD, available in white LED. WO1602N module is built-in with ST7028-1A IC; it communicates via I2C interface, viewing direction 6 o’clock, 1/17 duty, and 1/5 Bias.

This VATN WO1602N and our existing COG LCD WO1602G and COB LCD WH1602B models have the same VA and AA sizes but have a different pinout. WO1602G has a mental pinout, as WO1602N designed a FPC pinout for easy use to control the module by a ZIP connector. The supply voltage for logic of WO1602N is 3V to 3.6V, the typical value of 3.3V. This module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃.

This WO1602N VATN (Vertical Alignment Twisted Nematic) display offers superior performance to traditional STN/FSTN and DFSTN displays. This 16×2 VATN display features higher contrast and wider viewing angles than those currently provided by standard STN/FSTN/DFSTN displays. It is a negative mode display with a transmissive polarizer. In VATN LCD Display, liquid crystals naturally align vertically to the glass substrates.
