This module boasts a resolution of 256x64 pixels, encapsulated within a compact diagonal size of 2.08 inches, making it an ideal choice for applications where space efficiency and high-quality visual output are paramount.
Key Features and Specifications
Display Characteristics
The WEO025664A OLED module is designed with a 256x64 pixel array, providing a clear and sharp display suitable for a variety of applications. The display supports 4-bit grayscale, enabling the rendering of images with subtle gradations and enhanced visual depth. This feature is particularly beneficial for applications requiring detailed graphical representations, such as health devices and smart home interfaces.
Driver IC and Communication Interfaces
At the heart of the WEO025664A is the SSD1362 driver IC, a robust and versatile component that facilitates seamless communication between the display and the host system. The module supports multiple communication protocols, including:
- **6800/8080 8-bit Parallel Interface**: Ideal for high-speed data transfer, ensuring quick refresh rates and smooth display updates.
- **I2C (Inter-Integrated Circuit)**: A two-wire interface that simplifies connectivity and reduces the number of pins required, making it suitable for compact designs.
- **3-Wire and 4-Wire SPI (Serial Peripheral Interface)**: These interfaces offer flexible communication options, allowing for efficient data transfer with minimal wiring.
Electrical Characteristics
The WEO025664A operates with a logic supply voltage of 3V, ensuring compatibility with a wide range of microcontrollers and digital systems. The module features a 1/64 duty cycle, which optimizes power consumption while maintaining display performance. Under typical conditions, the display consumes approximately 15mA at a supply voltage of 12Vcc, with a 50% checkerboard pattern. This low power consumption makes it an excellent choice for battery-operated devices and energy-efficient applications.
Environmental Robustness
Designed to withstand harsh environmental conditions, the WEO025664A can operate within a temperature range of -40ºC to +80ºC. Its storage temperature range extends from -40ºC to +85ºC, ensuring reliability and longevity even in extreme environments. This robustness makes it suitable for a wide array of industrial and consumer applications, including outdoor meters and automotive displays.
Mechanical Design
The WEO025664A is engineered with a COG structure, resulting in an ultra-thin profile of just 1.61 mm. This slim design, combined with its lightweight construction, allows for integration into space-constrained applications without compromising on performance. The module is available in two versions to cater to different assembly requirements:
- **Soldering Version**: Features a directly soldered flex tail, enabling a super-thin profile and streamlined integration.
- **Hotbar Version**: Equipped with a ZIF (Zero Insertion Force) FPC (Flexible Printed Circuit) connector, facilitating easy and reliable connections.
Applications
The WEO025664A OLED module is versatile and can be employed in a multitude of applications, including but not limited to:
- **Smart Home Devices**: Ideal for user interfaces in smart thermostats, security panels, and home automation systems.
- **Meter Devices**: Suitable for energy meters, water meters, and gas meters, providing clear and reliable data display.
- **Personal Care Appliances**: Perfect for fitness trackers, smart watches, and health monitoring devices, offering crisp and readable displays.
- **Health Devices**: Applicable in medical equipment such as blood pressure monitors, glucose meters, and pulse oximeters, where accurate and clear display is critical.
