Overview
The OLED screen has advantages such as high contrast, low power consumption, wide viewing angles, and self-emissive pixels, making it suitable for small display applications like wearable devices and desktop widgets.
This OLED display has a size of 0.96 inches, with a resolution of 128×64 pixels, and uses I2C communication, driven by the SSD1306.
It is important to note the risk of screen burn-in and aging with OLED screens, so avoid displaying static images for extended periods.
