The WEN025664B model represents a state-of-the-art COF (Chip on Film) Graphic OLED display module, engineered to deliver exceptional visual performance across a wide range of applications. This advanced OLED module boasts a diagonal screen size of 3.12 inches, providing a resolution of 256x64 dots, which ensures crisp and detailed imagery suitable for both simple graphical representations and complex data visualization.
At the heart of the WEN025664B is the SSD1322 integrated circuit (IC), a highly efficient driver that supports multiple interface options including 8-bit 6800/8080 parallel interfaces and 3/4-line Serial Peripheral Interface (SPI). This flexibility in interface options allows for seamless integration into various electronic systems, catering to different design requirements and simplifying the development process for engineers.
The module's outline dimensions are meticulously designed at 89.2 × 44.0 mm, with an active display area measuring 76.78 × 19.18 mm. This compact form factor, combined with a high contrast ratio of 10,000:1, makes the WEN025664B an ideal choice for applications where space is at a premium and image clarity is paramount. The high contrast ratio not only enhances image quality but also ensures superior readability in diverse lighting conditions, including low-light environments.
One of the standout features of the WEN025664B is its support for 4-bit grayscale, which allows for the display of images with subtle gradations and depth. This feature is particularly beneficial in applications requiring detailed graphical content, such as medical imaging devices or sophisticated industrial control systems.
The module operates on a logic supply voltage of 3V, with a typical current consumption of 150mA at 3.0V VDD when displaying a 50% checkerboard pattern. This efficient power consumption is crucial for battery-operated devices, ensuring longer operational life and reduced energy costs. The driving duty of 1/64 further enhances the module's efficiency, making it suitable for energy-sensitive applications.
To facilitate ease of integration, the WEN025664B comes with a built-in Printed Circuit Board (PCB). This integrated PCB eliminates the need for additional PCB development, allowing customers to directly use wire connections for their specific applications. The inclusion of an integrated VCC circuit on the PCB further simplifies the design process, reducing the complexity and cost associated with external power supply components.
The module is also designed with practicality in mind, featuring four mounting holes on the PCB. These mounting holes provide a secure and straightforward method for installing the module in various applications, ensuring stability and reliability in end-use environments.
The WEN025664B is designed to withstand harsh operating conditions, with an operational temperature range of -40ºC to +80ºC and a storage temperature range of -40ºC to +85ºC. This robust temperature tolerance makes the module suitable for use in extreme environments, from freezing cold to scorching heat, without compromising performance.
In addition to the WEN025664B, there are several alternative models available within the same dimensional category, catering to different application needs:
- The WEX025664B series, which omits the metal frame and PCB, offering a more basic solution for cost-sensitive projects.
- The WEX025664B-CTP series, which not only excludes the metal frame and PCB but also incorporates a Capacitive Touch Panel (CTP) for interactive applications.
- The WEN025664B-CTP series, which includes all the features of the WEN025664B along with a CTP touch screen, making it ideal for applications requiring user interaction.
These variants provide designers with a range of options to choose from, depending on their specific requirements for functionality, cost, and user interaction.
In summary, the WEN025664B OLED module is a versatile and high-performance display solution, suitable for a wide array of applications including smart home devices, medical equipment, and industrial control systems. Its combination of high resolution, efficient power consumption, robust construction, and flexible interface options make it a preferred choice for developers looking to enhance the visual interface of their products. With its comprehensive feature set and reliable performance, the WEN025664B stands out as a leading solution in the OLED display market.
