Advantages of STN Graphic LCD:
Low Power Consumption: Ideal for battery-powered devices, especially in reflective mode where no backlight is required.
Compact Size: The 128x64 resolution allows for a compact form factor while still being large enough for basic graphics and text.
Cost-Effective: These displays are often inexpensive compared to other graphical displays like TFT or OLED, making them a popular choice for budget-conscious designs.
Easy Integration: Many of these displays can be interfaced easily with microcontrollers and come with well-supported libraries for quick implementation.
Improved Visibility: Compared to TN displays, STN offers better contrast and wider viewing angles, which is beneficial for user interfaces that need to be viewed from different angles.

Limitations:
Monochrome Display: Most 128x64 STN graphic displays are monochrome, which limits the complexity of graphics that can be displayed. Some versions may offer limited colors, but these are often in shades of blue or green.
Resolution Limitations: With 128x64 resolution, the display is fairly low resolution compared to modern color displays like TFT or OLED, limiting the detail of the graphics that can be shown.
Viewing Angle: While the viewing angles are better than traditional TN displays, they are still not as wide as those of OLED or TFT screens.
Backlight Required for Transmissive Models: If you are using a transmissive version of the display, you'll need a backlight, which will increase power consumption.
Key Differences:
| Characteristics | Positive STN LCD | Negative STN LCD |
|---|---|---|
| Text Color | Dark text (usually black) on a light background (white or light gray). | Light text (usually white or light gray) on a dark background (black or dark gray). |
| Background Color | Light background (white or light gray). | Dark background (black or dark gray). |
| Use Cases | Indoor applications, and handheld devices, where readability in normal lighting is needed. | Outdoor or low-light applications, power-sensitive devices, or for use in dark environments. |
| Power Consumption | Slightly higher in reflective mode due to a light background, but still low. | May be more power-efficient in reflective mode due to a dark background, reducing the number of active pixels. |
