0.91 Inch OLED Display 128x32 Resolution White 15pin FPC SPI Interface

Key Features:

1. Display Type: OLED (Organic Light Emitting Diode): OLED displays are known for their ability to produce deep blacks, high contrast, and vibrant colors. Unlike traditional LCDs, OLED pixels emit their light, which means no backlight is required. This results in a thinner form factor and lower power consumption, especially when displaying darker content.

2. Resolution: 128x32 pixels: This is a standard resolution for small OLED displays and provides enough clarity for simple graphical and textual applications.

3. Color: Most 0.91-inch OLED displays are monochrome (usually white, blue, or yellow on a black background), though some color OLED variants are available in red, blue, or even full color (RGB), but these are less common in such small displays.

4. Interface: SPI: A faster communication protocol that requires more wires but can transfer data at higher speeds, ideal for applications requiring faster updates.

5. Power Consumption: Low Power: OLED displays consume very little power, especially when displaying darker images. Since OLED pixels turn off individually, black areas on the display consume no power, making it highly efficient for battery-powered applications.

6. Contrast & Brightness:

   • High Contrast: OLEDs offer excellent contrast ratios, with true black levels since unlit pixels remain off.

   • Brightness: While OLED displays typically offer bright output (often around 100-200 nits), the small size of the 0.91-inch display means the overall brightness might be lower than larger OLED screens.

Detailed Specifications:

OLED Screens ( 0.42 inch~3.12 inch ):

We mainly develop small-middle sizes OLED displays, including 0.42", 0.49", 0.66", 0.78", 0.87", 0.91", 0.96", 1.12", 1.21", 1.3", 1.5", 1.54", 1.92", 2.08", 2.23", 2.42", 2.7", and 3.12", etc.

Considerations When Using 0.91-inch OLED Displays:

• Pinout and Wiring: Ensure that you use the correct wiring for the display type, whether I2C or SPI and verify that your microcontroller or board supports the chosen interface.

• Libraries: Many popular microcontroller platforms like Arduino and ESP32 have libraries to control 0.91-inch OLED displays, making integration easy.

• Power Supply: While OLEDs are power-efficient, ensure that your power supply is adequate for both the display and any other components in your project, especially if it’s a battery-operated device.

Popular 0.91-inch OLED Models:

• SSD1306: One of the most popular OLED drivers used in 0.91-inch displays. It’s typically a 128x32 resolution and supports both I2C and SPI interfaces. It has robust support in many libraries for various platforms like Arduino and ESP32.
