This blue OLED emits graphics while allowing the background to remain visible through the panel. It can place text or imagery over a fixed scene, giving the display a different visual role from an opaque screen.
The 1.5-inch, 128×64 panel uses an SSD1309 controller and an attached I2C driver board with 3.3V logic. The display measures 42×27mm, or 42×39mm including its driver board. Possible uses include layered displays and optical interface experiments.
