The WEA012864L is a high-performance graphic COG (Chip-on-Glass) OLED module with an integrated PCB, designed to deliver exceptional visual clarity and energy efficiency in a compact form factor. With a resolution of 128x64 pixels and a diagonal size of 1.28 inches, this module provides sharp and detailed graphics, making it suitable for a wide range of applications where space and power 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 the I2C 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 features of the WEA012864L is its PCB design, which includes mounting holes and 4x1 metal pins for easy installation and secure integration. The mounting holes allow for stable and secure attachment to the application, making the module suitable for environments where mechanical stability is important, such as industrial equipment or portable devices. The 4x1 metal pins provide a reliable connection interface, ensuring efficient communication between the module and the host system. The PCB outline size of 35.50 × 32.0 mm ensures that the module can be seamlessly integrated into compact designs, making it ideal for space-constrained applications.
The WEA012864L offers dual power supply options, supporting both internal Charge Pump supply and external VCC supply. This flexibility allows designers to choose the most suitable power configuration for their application, optimizing performance and power efficiency. The internal Charge Pump supply simplifies the power design by generating the necessary voltage internally, reducing the need for external components. On the other hand, the external VCC supply option provides additional flexibility for applications with specific power requirements. The logic supply voltage of 3V/5V and the display supply voltage of 7.5V (Internal Boots) ensure compatibility with a wide range of systems, making the module versatile and easy to integrate.
The low power consumption of the WEA012864L is another key advantage, particularly for battery-powered devices. The module's typical current consumption is 25mA at 3.3VDD when displaying a 50% checkerboard pattern, ensuring energy efficiency without compromising on performance. 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.
The WEA012864L is designed to operate reliably in a wide range of environmental conditions, with an operating temperature range of -40ºC to +80ºC. 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 -40ºC to +85ºC further enhances its durability, ensuring that it can withstand extreme conditions during transportation and storage. This robustness makes the WEA012864L a reliable choice for demanding applications.
The module is well-suited for a wide range of applications across various industries. In industrial control systems, the WEA012864L 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 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.
In summary, the WEA012864L 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 I2C interface, along with its dual power supply options, ensures compatibility with a wide range of systems and applications.
