OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When an electrical current is applied, a bright light is emitted. They are thinner and more efficient than LCD displays since they don’t require backlight. This OLED display embeds the SSD1306 single-chip CMOS OLED driver, which features contrast control (256 steps), display RAM and an oscillator.
Warning: screens are notoriously difficult to source reliably. This function is a good starting point to evaluate the technology, but you might need to refine the exact part reference if you move to volume production.
- Thin and efficient display
- Low power consumption
- Good durability and image quality
- Embedded 128 x 64 bit SRAM display buffer
- Screen saving continuous scrolling function in both horizontal and vertical direction
- Programmable Frame Rate and Multiplexing Ratio
Adafruit have developed a library available in their GitHub repository.
This function comes as a 96×16 black-and-white OLED screen which sits directly on the board, with an embedded SSD1306 controlled over I2C.
