256*32 big size graphic LCD Module ST7920/ST7921 20 pin industrial display

Product Description

A 256x32 graphic LCD module refers to a type of display that has a resolution of 256 pixels in width and 32 pixels in height. It is commonly used in applications where graphical information needs to be displayed, such as in industrial control systems, instrumentation, and other electronic devices.

These modules typically utilize a monochrome display technology, where each pixel can be individually controlled to display various graphical elements. The display may use technologies like STN (Super Twisted Nematic), FSTN (Film-compensated Super Twisted Nematic), or other similar LCD technologies.

Graphic LCD modules often provide built-in controllers that simplify the interface with a microcontroller or other controlling device. They may use standard communication protocols such as SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit) for data transfer.

When using a 256x32 graphic LCD module, you would typically need to send commands and data to the display to control individual pixels and create the desired graphics or text. The specific commands and protocols would depend on the module's datasheet and controller used.
