The WEA012864L (SPI) is a high-quality 1.28-inch graphic COG (Chip-on-Glass) OLED display module designed to deliver exceptional performance in a compact and energy-efficient package. With a resolution of 128x64 pixels, this module provides sharp and clear graphics, making it an ideal choice for a wide range of applications where visual clarity and space efficiency are critical. The module is built-in with the SH1106 IC, a reliable and efficient controller that ensures smooth operation and robust performance. The SH1106 IC supports a 4-Wire SPI interface, which simplifies communication with microcontrollers and other host systems, making it easier to integrate into various designs. Additionally, the module features a 1/64 driving duty, ensuring consistent and uniform display performance across the entire screen.
One of the key advantages of the WEA012864L (SPI) is its PCB design, which includes screw holes and a peripheral circuit for easy mounting and integration. The screw holes allow for secure and stable installation, making the module suitable for applications where mechanical stability is important, such as industrial equipment or portable devices. The peripheral circuit simplifies the design process by reducing the need for additional external components, enabling faster and more efficient integration into end products. This feature is particularly beneficial for designers looking to minimize development time and complexity.
The WEA012864L (SPI) is designed to operate reliably in a wide range of environmental conditions, with an operating temperature range of -40°C to +80°C. This makes it suitable for use in harsh environments, such as industrial control systems, outdoor IoT devices, and automotive applications, where temperature fluctuations are common. The module's storage temperature range of -40°C to +85°C further enhances its durability, ensuring that it can withstand extreme conditions during transportation and storage. This robustness makes the WEA012864L (SPI) a reliable choice for demanding applications.
The module is available in two emitting colors: white and yellow, providing flexibility for designers to choose the most suitable option for their specific application. The white OLED offers a bright and clear display, ideal for applications where high visibility is required, such as in medical devices or consumer electronics. The yellow OLED, on the other hand, provides a warm and distinctive appearance, making it suitable for applications where visual differentiation is important, such as in industrial control panels or automotive displays.
For applications that require an I2C interface, Winstar offers an alternative version of this module, the WEA012864L(I2C). This version provides the same high-quality display performance but with support for the I2C communication protocol, which is particularly useful for applications where minimizing the number of connection pins is critical. The I2C interface is ideal for compact designs and systems with limited I/O resources, making it a popular choice for wearable devices, IoT sensors, and other space-constrained applications.
The WEA012864L (SPI) is well-suited for a wide range of applications across various industries. In industrial control systems, the module can be used in control panels, meters, and instrumentation, where its high resolution and robust design ensure reliable performance in challenging environments. For portable and handheld devices, such as diagnostic tools, handheld scanners, and consumer electronics, the module's compact size, low power consumption, and easy integration make it an excellent choice. In IoT systems, the WEA012864L (SPI) can be integrated into smart sensors, wearable devices, and other connected technologies, providing a clear and efficient display solution. Additionally, the module's versatility makes it suitable for automotive applications, such as dashboard displays and infotainment systems, where its wide operating temperature range and durability are critical.
The low power consumption of the WEA012864L (SPI) is another key advantage, particularly for battery-powered devices. The self-emitting nature of OLED technology ensures that only the pixels that are actively displaying content consume power, resulting in significant energy savings compared to traditional LCD displays. This feature is especially important for portable and wearable devices, where extending battery life is a top priority.
In summary, the WEA012864L (SPI) is a highly capable and versatile OLED display module that combines high resolution, low power consumption, and ease of integration into a compact and robust design. Its support for the 4-Wire SPI interface, along with the optional I2C interface in the WEA012864L(I2C) version, ensures compatibility with a wide range of systems and applications. The module's wide operating temperature range, durable construction, and flexible mounting options make it a reliable choice for demanding environments. Whether used in industrial, portable, IoT, or automotive applications, the WEA012864L (SPI) delivers exceptional performance and reliability, making it a standout choice in the world of OLED displays.
