OLED, organic light emittIng diode. It works the way of stimulating organic semiconductor luminescent materials with an electric current, passing through complex particle motions, and finally emitting visible light. Tens of thousands of oleds do their job according to the input signal, and finally form a complete picture.
OLED is divided into monochrome, multi-color and colorful. OLED Display Card is the simplest basic monochrome type. With the display screen, you can show information and achive a variety of visual creativity, such as temperature, dialogue, and dynamic emoji.
OLED Display Card features UG-2864KSWLG01 folding type OELD module which provides 128x64 monochrome pixels. The OLED card uses SPI protocol to communicate with the Carduinol.
