The WEA160128B series is a high-performance 1.92-inch COG (Chip-on-Glass) graphic OLED display module, designed to deliver exceptional visual quality and versatility for a wide range of applications. With a resolution of 160x128 dots, this module provides sharp and detailed graphics, making it suitable for applications that require high-quality visual output. Built-in with the CH1120 OLED IC, the WEA160128B series supports a 4-wire SPI interface, ensuring efficient communication with microcontrollers or host systems. The module boasts a high contrast ratio of 10,000:1, offering excellent image clarity, sharpness, and consistency, even in challenging lighting conditions. This makes it an ideal choice for applications in medical devices, smart home systems, intelligent building controls, wearable technology, and industrial equipment.
One of the key features of the WEA160128B series is its inclusion of a PCB board, which provides four screw holes for secure mounting onto application products. This design enhances the module's durability and ease of integration, making it a practical solution for developers who require a robust and reliable display module. For customers who do not need a PCB board, the WEO160128B model is available as an alternative. The WEO160128B shares the same core specifications as the WEA160128B but omits the PCB, offering a more streamlined option for applications where space or mounting requirements differ.
The WEA160128B series is designed to operate on a logic power supply voltage of 3V to 3.3V, ensuring compatibility with a wide range of systems. The module's 1/128 driving duty and support for 16-level (4-bit) grayscale enable it to display detailed and nuanced graphics, making it suitable for applications that require high visual fidelity. The module's current consumption is 160 mA (typical value) when displaying a 50% checkerboard pattern, reflecting its efficient power management and suitability for battery-powered devices. This low power consumption, combined with the self-emissive nature of OLED technology, ensures that the module is both energy-efficient and capable of delivering vibrant, high-contrast visuals.
The OLED technology used in the WEA160128B series offers several advantages over traditional display technologies. Unlike LCDs, OLEDs are self-emissive, meaning each pixel generates its own light. This eliminates the need for a backlight, resulting in a thinner, lighter, and more energy-efficient display. Additionally, OLEDs can achieve true black levels and infinite contrast ratios, enhancing the visual quality of the display. The module also provides wide viewing angles, ensuring that the content remains clear and legible even when viewed from extreme angles. This is particularly beneficial for applications where the display may be viewed from various positions, such as in handheld devices or control panels.
The WEA160128B series 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 4-wire SPI interface supported by the WEA160128B series provides a simple and efficient communication protocol for interfacing with microcontrollers or other host systems. The SPI interface is known for its high-speed data transfer capabilities, making it ideal for applications that require fast refresh rates or dynamic content updates. The 4-wire configuration includes SCLK (Serial Clock), SDA (Serial Data), CS (Chip Select), and D/C (Data/Command) pins, which allow for precise control of the display and efficient data transmission. This interface is widely used in embedded systems, ensuring compatibility with a broad range of microcontrollers and development platforms.
The WEA160128B series is well-suited for a variety of applications, including medical devices, where its high resolution and grayscale support enable clear and detailed visual representation of data. In smart home and intelligent building systems, the module's high contrast and wide viewing angles ensure that information is easily readable from a distance or in varying lighting conditions. For wearable technology, such as smartwatches and sports watches, the module's compact size, lightweight design, and low power consumption make it an excellent choice. In industrial control panels, the module's durability and wide operating temperature range make it a reliable choice for displaying critical data in challenging environments.
In summary, the WEA160128B series is a highly capable and versatile OLED display module that combines advanced technology with practical design features. Its 160x128 resolution, CH1120 IC, and 4-wire SPI interface 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 WEA160128B series 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.
