1.3 Inch Square LCD Module: Compact & Vivid IPS Display
The 1.3 Inch Square LCD Display Module is a compact TFT solution designed for devices that require a 1:1 aspect ratio interface. With a resolution of 240×240 pixels and IPS technology, it delivers sharp, colorful visuals from any viewing angle, making it a superior alternative to monochrome OLEDs or segment displays.
Key Technical Features
1. True Square Form Factor (1:1)
Unlike standard rectangular screens, this module features a square Active Area of 23.4mm x 23.4mm. This shape is perfect for:
-
Smart Knobs: Thermostats, washing machine controllers, and audio volume dials.
-
Wearables: Smartwatches and fitness trackers.
-
Portable Instruments: Mini detectors and keychain gadgets.
2. Efficient 8-Bit MCU Interface
Powered by the widely supported ST7789 driver IC, this module utilizes an 8-Bit MCU interface.
-
Direct Control: It connects easily to standard microcontrollers (STM32, PIC, AVR) via an 8-bit parallel bus, allowing for fast data writing without the overhead of complex RGB timing.
-
Ease of Code: The ST7789 is supported by countless open-source libraries (e.g., LVGL, Arduino GFX), speeding up your development time.
3. Industrial Wide Temperature Range
Despite its small size, this screen is built for tough environments. It supports an operating temperature range of -20°C to +70°C, ensuring reliable performance in outdoor equipment or unheated industrial settings.

Engineering FAQ
Q: Can I use this with SPI instead of MCU interface?
A: The ST7789 driver IC supports both SPI and MCU interfaces. However, this specific module FPC is pin-mapped for 8-Bit MCU parallel interface. If you strictly need SPI, please contact us for a pin-compatible SPI version or check the FPC modification options.
Q: Is the backlight adjustable?
A: Yes, the LED backlight intensity can be controlled via PWM from your microcontroller to adjust brightness or save power.
Q: What is the “All o’clock” viewing direction?
A: This refers to the IPS (In-Plane Switching) technology. Unlike TN screens that invert colors when viewed from below, this screen maintains accurate colors from Top, Bottom, Left, and Right (80/80/80/80 degrees).
