Customer Reviews
Very fast response to email and after payment validated item got shipped with express air freight and received within few days. Items were brand new in condition and even had pin header soldered which is a big plus. Very happy overall and will buy again!

—— Andreas Anderssons

As always 100 % best service....

—— Evto-WEb Aps. Denmark

The display is bright! Worked as expected using the libraries from Adafruit mention in other reviews. Also must use the SPI_MODE3 setting in the Init. I used the Arduino Nano, VCC to 5V and BKL to 3.3V. (PN: SFTM130JY-7181AN)

—— Richard Ingram

It is a straight up HDMI monitor with Micro-USB for power and touch controls. It's one fancy trick is that it is a 5 point (capacitive) touch monitor so it works just like a phone or a laptop screen with taps, drags, pinches and other touch gestures. When in extended mode both switched to their native resolutions and the display was nice and sharp.

—— Darkwynd

Hello Janco, Hope you are well. We were very happy with the quality of the previous batch of 2.42 inch OLED displays that we brought from you (see below). We would like to place another order for XXXX pcs.

—— Libby

I have this set up as a monitor for a security system. It works great after I did some troubleshooting.

—— Michael Helms

Excellent work! Thank you I will keep your company in contact for next orders。

—— DEMAC S.A.

Overall a great monitor. I’m a road warrior and was looking a portable monitor that I could take with me to make my work more efficient. Overall impressed with the product. Screen looks good, is responsive, and colors/sharpness are good.

—— J Rau

Awesome little monitor for my projects.

—— Daniel Champagne

I got the samples within a week. Very fast delivery. This is a very nice display. Very sharp with good contrast. The viewing angles are a little better than some of the other displays I have used.

—— GeorgeB

Displays came well packaged with foam to protect the header pins against being bent in shipment. Came right up at the default 0x3C I2C address used by MicroPython's SSD1306 driver. Pre-soldered header is a time saver. Enough room for four lines by sixteen characters of tiny text. These are my new favorite displays. (0.91 OLED)

—— Detta

Easy enough to get set up, and good colors. Pure black is perfect, as expected from an OLED. Only issue I have is per-pixel writing - it takes about 1.5 seconds for a full refresh with my setup.

—— Ryan James

Great screens - were packed well and worked great!

—— Fletcher

This is not the first time we have ordered. At first, we ordered a trial batch of 10 pcs, then two times of 1000 pcs, and now 3000 pcs.

—— Josh

Hi Christina, The product we ordered, OLED 3.12inch display, have now been tested and all worked perfectly, 100%. Very happy with product, fast shipping and excellent customer service. We will place order for more displays in November. (SFOM312YZ7-25664WBYG-01) Best regards Andreas

—— Andreas Anderssons

Engineered for Minimalist Excellence: The 0.91-Inch OLED Display Module for Demanding Embedded Applications

 

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.

 

Key Design Parameters & Technical Superiority

  • 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.

 

Solve Your Embedded Design Challenges

  • 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.
