Understanding Passive Matrix OLED Technology
The Passive Matrix OLED (PMOLED) technology used in this display module leverages a simple but effective method of controlling pixel states. In a PMOLED, pixels are arranged in rows and columns, with each row driven in turn by the controller, while the individual pixels are addressed sequentially. This allows for efficient display operation, especially in applications where power consumption is a key consideration.
Advantages of Passive Matrix Technology
| Feature | PMOLED Technology | AMOLED Technology |
|---|---|---|
| Power Consumption | Low, ideal for low-power devices | Higher, more suitable for larger displays |
| Display Complexity | Simpler to implement and cost-effective | More complex, higher cost |
| Display Quality | Suitable for smaller displays | Higher contrast, better resolution for large screens |
| Lifespan | Long-lasting with proper use | Can degrade faster with heavy usage |
| Speed of Response | Slower refresh rate | Faster refresh rate |
PMOLED technology is widely used in applications where the display size remains compact, and the need for high-resolution graphics is moderate. It offers excellent energy efficiency while still providing crisp and clear visuals, making it an ideal solution for small handheld devices, wearables, and other portable electronics.
Display Resolution and Visual Characteristics
The 1.5-inch OLED display offers a 128×128 pixel resolution, ensuring high-definition output with clear text, graphics, and icons. With a dot size of 0.19mm x 0.19mm and a dot pitch of 0.21mm x 0.21mm, this module provides impressive pixel density, making it suitable for a variety of graphical outputs. Whether you’re displaying simple text, icons, or more complex graphical elements, this display ensures clarity and readability even in smaller form factors.
Viewing and Effective Area
The viewing area of the display measures 28.86mm x 28.86mm, while the effective display area is slightly smaller at 26.86mm x 26.86mm. This compact size ensures a dense and sharp display for applications that require a small screen size without compromising visual quality.
Connectivity and Interface Options
The module offers flexible connectivity options, supporting both the IIC (Inter-Integrated Circuit) and 4-SPI (Serial Peripheral Interface) communication protocols. These options allow designers to choose the best interface for their specific application, whether it’s for simple microcontroller-based projects or more complex systems requiring faster data transfer rates.
IIC vs. 4-SPI: Choosing the Right Interface
- IIC Interface: This two-wire interface is ideal for small systems where only a few devices need to communicate with the microcontroller. It simplifies wiring and is commonly used in low-power applications.
- 4-SPI Interface: This four-wire interface provides faster data transfer speeds and is suitable for systems where multiple devices need to be connected to the microcontroller.
Both interfaces offer robust solutions for system integration, with IIC being favored for its simplicity and 4-SPI offering higher performance for more data-intensive applications.
Compact Size and Versatile Applications
The 1.5-inch OLED display module is designed with space-saving in mind, making it perfect for small, portable, and embedded systems. With its compact dimensions of 34.0mm (L) x 47.0mm (W) x 2.7mm (max height), it can be easily integrated into a variety of devices where display real estate is limited.
