About this item SFTO085JY-7245AN
The Mini Square LCD 0.85 Inch 128x128 IPS TFT Display Module is a
compact and versatile display suitable for various applications,
particularly in small electronic devices. Here's a brief overview
of its features and specifications:
Features:
- Size: 0.85 inches diagonal.
- Resolution: 128x128 pixels, providing decent clarity for various
graphics and text.
- IPS Technology: In-Plane Switching (IPS) offers wider viewing
angles and better color reproduction compared to standard TFT
displays.
- Interface: Utilizes SPI (Serial Peripheral Interface) for
communication, which simplifies connection with microcontrollers
and other devices.
- Driver IC: Typically uses the GC9107 driver, which is specially
designed for driving small TFT displays.
- Pin Count: 12-pin configuration allows for compact integration into
designs.
- Power Requirements: Generally operates at low voltage, making it
suitable for battery-powered applications.
- Color Depth: Supports RGB color, enabling vibrant displays.
Applications:
- Wearable Technology: Due to its small size, it's ideal for
smartwatches and fitness trackers.
- IoT Devices: Displays status or alerts for Internet of Things
devices.
- Industrial Applications: Can be used in control panels or
measurement devices.
- Embedded Projects: Perfect for DIY electronics projects involving
microcontrollers (like Arduino or ESP32).
Usage:
To use this display module, you'll typically connect it to a
microcontroller or development board via SPI. Libraries are often
available for popular platforms (like Arduino) to help simplify the
coding process required to interface with the display.
Considerations:
- Contrast and Brightness: Ensure that the module is suitable for
your application's lighting conditions.
- Viewing Angles: While IPS technology enhances this aspect, check
for specific angles to ensure it meets your needs.
- Driver Support: Familiarize yourself with the library and functions
available for interacting with the GC9107 chip.
Conclusion:
The Mini Square LCD 0.85 Inch 128x128 IPS TFT Display Module is a
great choice for compact applications requiring a colorful, sharp
display. Remember to check for compatibility with your specific
microcontroller platform and consider power management in your
design.
