Winstar 16x2 Yellow Green LCD Display Module

The Winstar 16x2 Yellow Green LCD Display Module is a 16x2 character display with a yellow-green reflective STN screen that is readable without a backlight.

Overview

The WINSTAR WH1602B-NYG-JT uses STN (Super Twisted Nematic) positive reflective technology, which relies on ambient light rather than a power-hungry backlight. This makes it a suitable option for low-power applications. The module features a built-in ST7066U controller IC, which provides a default 6800-series interface supporting 4-bit or 8-bit parallel communication. This simplifies integration into microcontroller projects and electronic systems.

Display Format

• Character format of 16 columns by 2 rows
• Each character composed of a 5x8 dot matrix, including a cursor
• Reflective viewing mode optimised for readability under ambient light
• Yellow/green display colour with a 6 o'clock viewing direction

Power and Operation

The module offers a logic voltage compatible with 3V to 5V DC. Optional negative voltage generation supports operation from a single +3V power supply, which may suit battery-powered equipment. The operating temperature range is -20°C to +70°C.

Physical Details

The module has a compact design that measures 3.3 x 1.5 x 4.3 (width x depth x height) and weighs 30 gm, allowing it to fit into space-constrained devices.

Applications

It is suitable for prototypes, embedded systems, instrumentation, and DIY electronics projects. It supports English, Euro, and Japanese character sets, providing a practical display option for a range of electronic designs.
