The WEO012864A is a 1.54-inch graphic OLED display module from Winstar, designed to deliver high-quality visuals in a compact and energy-efficient form factor. With a resolution of 128x64 pixels and a diagonal size of 1.54 inches, this module is ideal for applications that require clear and detailed graphical or textual information. The module dimensions are 42.04 x 27.22 mm, with an active area (AA) size of 35.05 x 17.51 mm, making it a space-saving solution for a variety of devices. Built-in with the SSD1309 controller IC, the WEO012864A supports multiple communication interfaces, including 6800/8080 8-bit parallel, I2C, and 4-wire SPI, offering flexibility for integration into diverse systems.
One of the key features of the WEO012864A is its chip-on-glass (COG) structure, which contributes to its ultra-thin design, with a depth of just 1.41 mm. This slim profile, combined with its lightweight construction, makes the module an excellent choice for applications where space and weight are critical considerations. The OLED technology used in this module eliminates the need for a backlight, resulting in lower power consumption and a thinner, lighter display compared to traditional LCDs. Additionally, OLEDs provide true black levels, high contrast ratios, and wide viewing angles, ensuring that the content remains clear and legible even when viewed from extreme angles.
The WEO012864A is designed to operate reliably across a wide temperature range, from -40ºC to +80ºC, making it suitable for use in both extreme cold and hot environments. This robustness ensures consistent performance in demanding applications, such as outdoor equipment, industrial control systems, or automotive displays. Furthermore, the module can be stored at temperatures ranging from -40ºC to +85ºC, ensuring its durability and longevity even under harsh storage conditions.
The module's support for multiple communication interfaces ensures compatibility with a wide range of microcontrollers and host systems. The 6800/8080 8-bit parallel interfaces are ideal for applications requiring high-speed data transfer, while the I2C and 4-wire SPI interfaces provide simpler and more compact solutions for systems with limited pin availability. This flexibility allows designers to choose the most appropriate interface based on their specific requirements, whether it be for speed, simplicity, or compatibility with existing hardware.
The WEO012864A is well-suited for a variety of applications, including wall/meter devices, home automation systems, POS (Point of Sale) systems, Cloud/IoT systems, handheld instruments, intelligent technology devices, energy systems, automotive displays, communication systems, and medical instruments. In smart home and IoT applications, the module's high contrast and wide viewing angles ensure that information is easily readable from a distance or in varying lighting conditions. For portable and handheld devices, its compact size, lightweight design, and low power consumption make it an excellent choice. In industrial and automotive applications, the module's durability and wide operating temperature range make it a reliable choice for displaying critical data in challenging environments.
In summary, the WEO012864A is a highly capable and versatile OLED display module that combines advanced technology with practical design features. Its 128x64 resolution, SSD1309 IC, and support for multiple communication interfaces make it a powerful solution for applications requiring clear and dynamic visual displays. The module's wide operating temperature range, low power consumption, and ultra-thin design further enhance its appeal, making it suitable for a wide range of industries and use cases. Whether used in smart home systems, portable electronics, industrial equipment, or medical instruments, the WEO012864A delivers the performance, reliability, and efficiency needed to meet the demands of modern electronic designs. For detailed technical specifications and integration guidelines, designers are encouraged to refer to the module's datasheet.
