Crisp Visuals and Flexible Integration

This graphic LCD module delivers sharp, high-contrast visuals on its 128x32 pixel monochrome screen, making it suitable for displaying both text and simple images in embedded and industrial applications. Its backlight, available in either white or blue, ensures visibility in various lighting conditions, while the 6 o'clock viewing angle allows for mounting flexibility. The module supports multiple interfaces-including parallel and SPI-making integration straightforward for a range of electronic designs.

Robust and Reliable for Industrial Environments

Designed for durability, this LCD module operates effectively across a wide temperature range (-20C to +70C) and enduring high humidity environments (10%-90% RH, non-condensing). The rugged construction and low power consumption (LED backlight approx. 45 mA typical) make it ideal for continuous use in demanding settings such as industrial control panels, instrumentation, and embedded systems. The standard 20-pin through-hole connector supports secure PCB mounting.

FAQ's of 128x32 Graphic LCD Module:

Q: How can I connect the 128x32 Graphic LCD Module to my microcontroller?

A: You can interface this LCD module with your microcontroller using either an 8-bit/4-bit parallel connection or SPI serial communication, depending on your system's requirements and the available pins.

Q: What are the main benefits of using this LCD module in embedded or industrial instruments?

A: The primary benefits include high contrast for clear readability, low power consumption for energy efficiency, robust operation across broad temperature and humidity ranges, and flexible integration via standard parallel or SPI interfaces.

Q: When should I choose the blue backlight variant over the white backlight?

A: The blue backlight variant is optimal for environments with low ambient light, as it offers improved readability and a distinctive appearance. The white variant provides a more neutral look and can be preferable in well-lit environments.

Q: Where can I mount this LCD module in my application?

A: This module is designed for through-hole or PCB mounting, making it suitable for integration into control panels, display housings, and electronic enclosures commonly found in industrial and embedded systems.

Q: What process is involved in initializing the display for use?

A: To initialize the display, you need to supply 5V DC power, connect the interface pins to your MCU, and configure the controller (ST7920 or compatible) according to the desired communication mode (parallel or SPI). Initialize the LCD using the recommended sequence provided in the controller's datasheet.

Q: How can I use this module to display both text and simple graphics?

A: The 128x32 pixel resolution allows you to display formatted text and simple graphic elements by writing appropriate data to the display's memory via commands and data sequences supported by the ST7920 controller.

Q: What is the typical response time and viewing area of the module?

A: This LCD module offers a typical response time of approximately 150 ms and a viewing area measuring 54.0 x 18.0 mm, delivering a clear and responsive display within its compact form factor.
