This is a small flexible, grayscale OLED display. That’s right, we said flexible. We’ve been hearing about flexible displays for years, it’s finally here! You can’t fold it like paper but this OLED from Wisechip can be bent to a 40mm radius without damage. The display is than 0.5mm thick, less than 0.5 grams, and can display some impressive graphics with great contrast.

The OLED display is 1.81" long with 160x32 4-bit grayscale pixels. The interface is 3-wire SPI and each pixel requires 4 bits. This means you will need a processor capable of storing a local array of 80*32 = 2,560 bytes in order to truly flex (pun intended) the power of the grayscale display. Basic 8-bit Arduinos can communicate with the display and do things like text but graphics will be tricky.

The carrier board generates the 12V required to drive the OLED display. The carrier board also has a signal buffer so that you can drive the display from any 3.3V or 5V microcontroller. However, because of the nature of the TXB0104 you must power the board with 3.5V or more. Your microcontroller can be 3.3V or 5V but we recommend you power the carrier board with 5V.

We are eager to get this product available so library support is limited. We’ve ported the MicroLED library so you can do things like print text (two sizes) and the next 7-segment number font. The library is not complete and we welcome any help you’d like to provide. Additionally, we’ve posted examples of pushing locally-stored graphics to the display.
