O128O064FGPP3N0000

O128O064FGPP3N0000 is a liquid crystal display (LCD) module designed for use with Arduino, STM32, and Raspberry Pi boards. The module features an LCD display with a resolution of 128x64 dots and a background light. The LCD duration is adjustable and backlight brightness can be controlled. The controller is the ST7565R, and the module can be connected via I2C or SPI protocol.

Application Fields

This module has a wide range of applications, the most common being LCD display for text, graphical information, and sensor data. It can be used for nowcasting and weather reporting, industrial control, and various automotive applications. It is also suitable for power monitoring, sound and vibration monitoring, and inventory management.

The module is compatible with both 2.4” and 2.8” LCD displays, and can be used with RPi, Arduino, and STM32 boards. A variety of fonts and symbols can be displayed, and the module is capable of multiple display modes, including Standard, PMOLED, and U8GLIB.

Working Principle

The O128O064FGPP3N0000 module operates on the principle of liquid crystal display. It works by applying an electric field to a liquid crystal layer between two parallel transparent surfaces. The electric field causes the individual liquid crystal molecules to align themselves in a specific pattern, to produce a desired image on the display. The molecules stay in this pattern until an electric field of the opposite polarity is applied and the image is erased.

The ST7565R controller controls the display in various modes. In the Standard mode, it controls the movement of the graphic cursor, enabling the user to enter and view data on the LCD display. In the PMOLED mode, the display is controlled using parallel ports. In the U8GLIB mode, the controller can be programmed via the U8glib library for various types of applications.

The module is powered by a 5V DC power supply, which is provided by the host board. The display supports two types of interfaces - I2C and SPI. The I2C interface can be used to exchange data between the module and the host board, while the SPI interface is used to configure the LCD display.
