Description

WO1602J model is a COG 16-characters by 2-lines VATN module with VA Negative Transmissive LCD, available in white LED. This WO1602J module is built-in with ST7028-1A IC; it supports I2C interface, viewing direction at 12 o’clock, 1/17 duty, and 1/5 Bias.

The supply voltage for logic of WO1602J is 3V to 3.6V, the typical value of 3.3V. This VATN WO1602J and our existing COG LCD WO1602G have the same outline dimension of 74.2 x 25.2 mm and feature the same metal pinout. Also, the VA and AA sizes of WO1602J are the same as WH1602B. We designed twin LED dices to increase the backlight brightness for the WO1602J VATN model. This module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃.

The VATN (Vertical Alignment Twisted Nematic) display features a wide viewing angle and high contrast ratio; therefore, it’s very suitable for many applications. Below are the examples for reference.

Industrial: automotive application, digital meter, UPS.
Medical: medical device & medical equipment.
Home appliance: audio system, coffee machine, microwave oven.
