OLED (Organic Light-Emitting Diode) means that the screen consists of all small LEDs (each pixel equals 1 LED). As a result, the display does not require a backlight and is much more economical to use. In addition, this gives a much higher contrast, making this display very clear and legible despite its size. This display can be addressed via the I2C protocol, so that only 2 wires can be used to call 128x32 = 4096 pixels. Dimensions: 38 x 12 x 2.4 mm (HxWxD). https://elecena.pl/product/27738954/opencircuit-oled-display-128-x-32-i2c-blue 2025-01-22 https://elecena.pl/product/27738954/opencircuit-oled-display-128-x-32-i2c-blue 2025-04-06 https://elecena.pl/product/27738954/opencircuit-oled-display-128-x-32-i2c-blue 2025-04-07 https://elecena.pl/product/27738954/opencircuit-oled-display-128-x-32-i2c-blue 2025-04-20 https://elecena.pl/product/27738954/opencircuit-oled-display-128-x-32-i2c-blue 2025-11-06 https://elecena.pl/product/27738954/opencircuit-oled-display-128-x-32-i2c-blue 2026-02-23 https://elecena.pl/product/27738954/opencircuit-oled-display-128-x-32-i2c-blue 2026-02-25 https://elecena.pl/product/27738954/opencircuit-oled-display-128-x-32-i2c-blue 2026-03-25 https://elecena.pl/product/27738954/opencircuit-oled-display-128-x-32-i2c-blue 2026-03-27 https://elecena.pl/product/27738954/opencircuit-oled-display-128-x-32-i2c-blue 2026-04-14
