Our 1.46 range currently covers 3 part numbers at 128x128, driven by SSD1351 (colour) or SSD1327Z (mono) over Parallel, SPI and I2C, in full colour or monochrome. It is a genuinely square 128x128 canvas, offered in both full colour and monochrome.
Part numbers in this group
Mechanical details
Outline and active area dimensions differ slightly between part numbers, so check the drawing on each product page before finalising the bezel cut-out. Panel thickness stays around 1.2 to 1.4 mm on the monochrome builds, which lets the module sit almost flush behind a cover window.
Interface and driver
These modules run on the SSD1351 (colour) or SSD1327Z (mono), and the interface options are Parallel, SPI and I2C. On the I2C builds only four pins are needed (VCC, GND, SCL, SDA), which is why this group is common in Arduino, ESP32 and STM32 projects as well as in production hardware. The parallel and SPI builds suit hosts that need a faster refresh for animation or waveform drawing.
Where this size fits
Typical uses are compact graphical interfaces, portable instruments, smart home controllers and round dial replacements. See also the 1.3 inch page if space is tighter; the 1.69 inch page if you need more viewing area.
What resolution does the 1.46 group come in?
The standard build is 128x128. Portrait and alternative formats are listed in the table above.
Can I run these from an Arduino or ESP32?
Yes. Choose an I2C part number and the wiring is four pins; libraries for the SSD1306, SH1106, SH1107 and SSD1322 families are widely available. SPI builds give a faster refresh but need two more pins.
Is a wide temperature version available?
Selected part numbers in this group are built for -40 °C to +80 °C operation. Tell us the ambient range your product has to survive and we will confirm which builds are qualified for it.
What can be customised?
On this size we regularly adjust the FPC length and pinout, the connector type, the cover glass and the adapter PCB. Changes to the glass itself need tooling, so they only make sense at volume - we will say so honestly rather than quote an unrealistic MOQ.
Custom builds and samples
As a China based display company and module supplier, we hold stock of the standard part numbers on this page and ship samples in one to two weeks. Send your size, resolution, interface and temperature requirements and we will confirm feasibility with a drawing within one working day.
