The EA W202B-NLW is an LCD display module commonly used in applications such as embedded industrial, medical and military products. It is a type of Numeric/Character LCD display that is resistant to shock, temperature, and ESD, making it well suited for rugged environment operations. This LCD display module offers great cost-effectiveness in a small package.

The EA W202B-NLW utilizes a TN-LED Transflective LCD display which offers the user a contrast ratio of 300:1 over a wide temperature range and a viewing angle of 160°. Each module can produce a resolution of 128x64 pixels with up to 16 gray scales. It is powered by a 4 bit 6800 interface and is driven by an LCD controller. The LCD controller allows a single board to control up to 128 individual LCDs.

The EA W202B-NLW has a NEMA 4 rating which basically means that it is protected against dust, moisture and other environmental contaminants. It also has an IP65 rating, which makes it waterproof and dustproof. Furthermore, it features a wide operating temperature range of -20°C to +70°C, making it suitable for prolonged outdoor usage.

The working principle of the EA W202B-NLW is based on the principle of electro-optic effect. When an electric field is applied to a liquid crystal material, the optical properties of the crystal will change due to the electric field produced, resulting in a change in the transmitted light and thus an image on the display. This effect is used in the EA W202B-NLW to create images with different gray scales on the LCD display.

The EA W202B-NLW requires a few external components to function. The most important components are the microcontroller and the DC supply. In addition, some additional components like resistors for voltage limiting, capacitors for potentiating signals, and resistors for driving the LCD matrix might be needed depending on the application.

The EA W202B-NLW is designed for embedded industrial applications such as PLCs, process control instrumentation, data loggers and medical devices. It is also suitable for automotive, military and other rugged environment applications. The module has various features such as low power consumption with high contrast LCD display, long life LED backlight, and wide viewing angle.

The EA W202B-NLW, with its superior cost-effectiveness and robust performance, is one of the best LCD display modules available today, making it an ideal choice for embedded applications. It is easy to use and has a wide range of applications making it suitable for both commercial and industrial purposes.
