2.7 Inch LCD Screen 128x64 Graphic LCD Display FSTN White Backlight 20PIN FPC
FSTN (Film Super Twisted Nematic) Technology:
- FSTN is an enhancement of STN (Super Twisted Nematic) technology. It uses two film layers and optimizes the liquid crystal alignment to enhance contrast and viewing angles.
- Benefits of FSTN:
- Improved Contrast: FSTN technology allows for better contrast than traditional TN (Twisted Nematic) and even standard STN, making the display easier to read under various lighting conditions.
- Better Viewing Angles: The display can be viewed from a wider range of angles without significant distortion.
- Reflective and Semi-Reflective: FSTN displays can work well in both reflective (no backlight needed) and semi-reflective modes (with backlight), making them power-efficient for portable devices.

Interfacing:
A 128x64 COG FSTN LCD can interface with microcontrollers through various methods, including parallel or serial (I2C/SPI) communication:
-
Parallel Interface: Involves multiple data pins to transfer the information, typically used in older or high-speed applications.
-
Serial Interface: A more modern approach where only a few pins (typically 2–4) are used for communication, making wiring easier and reducing complexity. I2C or SPI are commonly used.
Example Wiring (Using I2C for 128x64 COG FSTN LCD):
If the 128x64 COG FSTN LCD uses I2C, you can wire it as follows:
-
VCC → 5V (or 3.3V, depending on the display's voltage requirement)
-
GND → GND
-
SDA → A4 (on Arduino Uno)
-
SCL → A5 (on Arduino Uno)
