The WEO160128B is a high-resolution 1.92-inch COG (Chip-on-Glass) graphic OLED display module, designed to deliver exceptional visual performance in a compact and energy-efficient form factor. With a resolution of 160x128 pixels, this module is capable of displaying detailed graphics and text, making it an ideal choice for applications that require high-quality visual output. The integration of the CH1120 IC ensures robust control and driving capabilities, while its support for multiple communication interfaces, including 6800/8080 parallel interfaces, I2C, and 4-wire SPI, provides designers with unparalleled flexibility in system integration. This versatility makes the WEO160128B suitable for a wide range of applications, including medical devices, smart home systems, intelligent building controls, wearable technology, and industrial control panels.
One of the standout features of the WEO160128B is its 4-bit grayscale support, which allows for the display of up to 16 levels of brightness. This capability enhances the visual richness of the display, making it suitable for applications that require detailed graphics or subtle shading. The module boasts a high contrast ratio of 10,000:1 (typical value), ensuring that images and text appear sharp and vibrant, even in challenging lighting conditions. This high contrast ratio, combined with the OLED's ability to achieve true black levels, results in a display that is both visually striking and easy to read.
The WEO160128B operates on a logic supply voltage of 3V and a display supply voltage of 12V, ensuring efficient power management and compatibility with a wide range of systems. The module's low power consumption is further enhanced by the self-emissive nature of OLED technology, which eliminates the need for a backlight. This not only reduces power usage but also contributes to the module's ultra-thin and lightweight design, making it an excellent choice for space-constrained applications such as smartwatches, fitness trackers, and portable medical devices.
The module's support for multiple communication interfaces ensures compatibility with a wide range of microcontrollers and host systems. The 6800/8080 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 WEO160128B is designed to operate reliably in a wide range of environmental conditions. It can function within a temperature range of -40°C to +80°C, making it suitable for use in both extreme cold and hot environments. This robustness ensures that the module can perform consistently in demanding applications, such as outdoor equipment, industrial control systems, or automotive displays. Additionally, the module can be stored at temperatures ranging from -40°C to +85°C, ensuring its longevity and performance even under harsh storage conditions.
The OLED technology used in the WEO160128B offers several advantages over traditional display technologies. In addition to its high contrast ratio and wide viewing angles, OLED displays provide faster response times compared to LCDs, making them suitable for applications that require dynamic content or rapid updates. The module's compact size and lightweight design make it an excellent choice for portable devices, where space and weight are critical considerations. Its low power consumption extends battery life, enhancing the usability of devices such as smartwatches, fitness trackers, and portable medical devices.
In smart home and intelligent building applications, the WEO160128B's high contrast and wide viewing angles ensure that information is easily readable from a distance or in varying lighting conditions. For industrial control panels, the module's durability and wide operating temperature range make it a reliable choice for displaying critical data in challenging environments. The module's 4-bit grayscale support and high resolution also make it suitable for medical applications, where clear and detailed visual representation of data is essential.
In summary, the WEO160128B is a highly capable and versatile OLED display module that combines advanced technology with practical design features. Its 160x128 resolution, CH1120 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 compact design further enhance its appeal, making it suitable for a wide range of industries and use cases. Whether used in medical devices, smart home systems, wearable technology, or industrial equipment, the WEO160128B delivers the performance, reliability, and efficiency needed to meet the demands of modern electronic designs.
