0.91 INCH OLED DISPLAY Features
OLED displays are high contrast and high-resolution displays, so they provide a good readability for users. There is no backlight on OLED, and it uses independent-illuminated pixels, so, it is thinner, and more elegant in compare to LCDs. The driver chip is SSD1306, which provides I2C communication.
SSD1306 is a driver module for dot-matrix display systems. It is used for common cathode type displays and is suitable for many portable applications such as mobile phones, MP3 players, calculators, etc.
