0.91 Inch OLED Display Blue 128x32 Pixels SSD1306 Driver 15pin Soldering FPC

Key Features:

1. Display Type: PMOLED (Passive Matrix OLED): As previously mentioned, PMOLED displays are based on passive matrix technology, which uses a simpler design to control the pixels. They don't require backlighting since each pixel emits its own light, resulting in higher contrast and more vibrant colors compared to traditional LCDs.

2. Resolution: 128x32: Lower resolution, suitable for displaying basic text or small icons

3. Color: Most 0.91-inch PMOLED displays are monochrome, meaning they typically display white or blue on a black background. Some models may offer other colors such as yellow, red, or green. However, they are generally not full-color like AMOLED displays.

4. Low Power Consumption: PMOLED displays are very power-efficient, especially when displaying darker content. Since OLEDs emit their light, they do not require a backlight, and only the pixels that need to be lit consume power. This makes them ideal for battery-powered applications like wearables and small embedded devices.

5. Interface: I2C or SPI interfaces: These are the most common communication protocols used for connecting PMOLED displays to microcontrollers like Arduino, ESP32, or Raspberry Pi

6. Viewing Angle and Contrast: OLED displays, including PMOLEDs, offer excellent contrast with true black levels because they don’t need a backlight, and each pixel emits its light. They also offer a wide viewing angle, which means you can see the display clearly from different angles.

7. Size: 0.91 inches refers to the diagonal measurement of the screen. This is a very small form factor, which is typically used for compact applications.

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.

Disadvantages of 0.91-inch PMOLED Displays:

1. Limited Resolution: Due to their small size, 0.91-inch PMOLED displays often have low resolution (e.g., 128x32 or 128x64 pixels). This makes them unsuitable for displaying complex images or videos and limits the amount of information that can be displayed at once.

2. Lower Brightness: While OLED displays generally have good brightness, the small size and passive matrix technology of PMOLEDs often result in lower brightness compared to larger or active-matrix displays.

3. Burn-In Risk: Like all OLED displays, PMOLEDs are susceptible to burn-in or image retention, particularly when static images (e.g., logos or icons) are displayed for extended periods.

4. Limited Color: Most 0.91-inch PMOLED displays are monochrome, which limits their ability to display full-color images or video.

5. Refresh Rate: PMOLED displays have slower refresh rates than AMOLED displays, which may be noticeable in applications requiring quick changes or dynamic content, such as animations or video.
