0.91 Inch OLED Display 128x32 Pixels Blue 12PIN SSD1306 with 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 own 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 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:

   • I2C (Inter-Integrated Circuit) or SPI (Serial Peripheral Interface) are commonly used communication protocols for connecting these displays to microcontrollers or single-board computers like Arduino, Raspberry Pi, or ESP32.

     • I2C: A two-wire interface (SCL and SDA) that simplifies wiring but is slower than SPI.

     • 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.

Advantages of 0.91-inch OLED Displays:

• Compact Size: Perfect for applications where space is limited.

• High Contrast & Clarity: Deep blacks and bright whites provide good readability even in low-light conditions.

• Low Power Consumption: Especially beneficial for battery-powered devices.

• No Backlight Required: The self-emissive nature of OLED allows for thinner, more energy-efficient displays.

• Wide Viewing Angle: OLEDs offer a consistent image even at extreme viewing angles, which is important in many embedded and wearable devices.

Disadvantages:

• Limited Resolution: A small display with a low resolution may limit the amount of information that can be displayed at once, making it better suited for simple text or small icons.

• Cost: Although prices have dropped significantly, OLED displays can still be more expensive compared to basic LCDs or other types of small screens.

• Blue OLED Degradation: Over time, blue OLED pixels may degrade faster than red or green pixels, causing color imbalance in some displays, though this is typically a concern in long-term or high-usage scenarios.
