Saef Technology Limited presents the SFOM091JY-12832WB-01, a high-performance 0.91-inch PMOLED display module designed for engineers and developers who require ultra-compact, low-power, and reliable displays for embedded systems, wearable devices, IoT interfaces, and industrial instrumentation. With its crisp 128x32 resolution, I²C interface, and robust SSD1306 driver, this module delivers exceptional clarity and ease of integration in space-constrained designs across Europe and the United States.
Ultra-Compact Form Factor:
Measuring only 38.0 x 12.0 x 3.1 mm, this display is ideal for wearable tech, medical monitors, smart sensors, and portable instruments where every millimeter counts.
High-Contrast PMOLED Technology:
Featuring a 2000:1 contrast ratio and 150–180 cd/m² brightness, this OLED delivers sharp, self-emissive pixels with wide viewing angles and no backlight—perfect for low-light or sunlight-readable applications.
Wide Operating Temperature Range:
Rated for -40°C to 70°C, this module performs reliably in extreme environments, from industrial automation to outdoor wearables.
Low Power Consumption:
With sleep mode currents as low as 1 μA (VDD) and 2 μA (VCC), this display extends battery life in power-sensitive designs.
Flexible Power Architecture:
Supports both external VCC (6.4V–9V) and internal DC/DC conversion from VBAT (3.5V–4.2V), simplifying power system design.
I²C Interface with Full Command Control:
Based on the industry-standard SSD1306, the module offers complete programmability for multiplex ratios, COM scan direction, contrast, pre-charge periods, and VCOMH levels—enabling fine-tuned optimization for your application.
Struggling with limited PCB real estate?
Our 0.91-inch OLED fits into tight layouts with a simple 4-pin interface (GND, VCC, SCL, SDA), reducing routing complexity and BOM cost.
Need a display that works in freezing or high-temperature environments?
With an operating range of -40°C to 70°C and full compliance with industrial reliability testing (including vibration, ESD, and temperature cycling), this module is built for harsh conditions.
Concerned about power management in battery-operated devices?
The integrated DC/DC converter and ultra-low sleep currents enable years of operation on a single coin cell.
Looking for a display that supports custom font colors or graphics?
While standard models come in white or blue, Saef offers free semi-custom modifications including color tuning, custom pinouts, firmware tweaks, and even touchscreen integration (RTP/CTP) upon request.
ISO 9001:2015 & ISO 14001:2015 Certified – Your assurance of quality and environmental responsibility.
Full SSD1306 Command Support – Datasheet includes detailed timing diagrams, initialization sequences, and power-up/down protocols.
Reliability Tested – Includes high/low temperature operation, storage, humidity, vibration, ESD, and drop tests.
Engineer-to-Engineer Support – Access to technical documentation, sample code, and direct factory engineering consultation.
