SSD1306 OLED displays for microcontrollers

If you want to digitally display data with a microcontroller, you can't get around an SSD1306 OLED in the short or long term. In direct comparison to their close relative, the LCDs ("Liquid Crystal Displays"), the use of OLED displays brings a variety of additional features that enable versatile use. Unlike LCDs, where characters are displayed exclusively within predefined segments, an SSD1306 OLED display allows you to control the individual pixels directly.
Combined with the fact that OLED displays do not require additional backlighting to display the pixels, this allows for a crisp display of numbers, letters, and custom shapes or animations.

Even though the designation is duplicated, we use the term "OLED Display" in this description for simplicity. The designation SSD1306 refers here to a type designation of the chip of the company Adafruit installed on the OLED. 

Appearance of the SSD1306 OLED displays

OLEDs are usually monochrome displays. However, in our online store you can also find single-color or multi-color versions. 
Unlike LCDs, the dimensions of OLEDs are given in pixels. A display with the type designation "SSD1306 OLED 128x64, 0.96"" thus has 128 pixels in width and 64 pixels in height, which extend to a diagonal of 0.96 inches. The size of the individual pixels varies relative to the length of the diagonal. The individual pixels of a display with the type designation "SSD1306 OLED 128x64, 1.3"" are thus considerably larger than those of the 0.96" version, while the number of pixels remains the same.
