The WEA012840A series is a graphic OLED display module featuring an active area with a diagonal size of 1.3 inches and a resolution of 128x40 dots. The module comes with an integrated PCB, eliminating the need for customers to design separate PCBs. Additionally, screw holes on the PCB simplify installation. This display is ideal for applications such as gaming keyboards and networking equipment. The compact OLED 128x40 display offers exceptional clarity and vibrant visuals, making it the perfect choice for devices that require small, high-quality screens. With a contrast ratio of up to 10,000:1, it guarantees sharp text and images.
This 128x40 OLED display utilizes a COG (Chip-on-Glass) structure, providing a compact and efficient form factor, perfect for space-constrained applications. The flexible FPC (Flexible Printed Circuit) is slightly offset to the left, with the IC centrally positioned on the module. This design ensures the module's compact form factor and facilitates easy integration into various hardware configurations. Powered by the SH1106 OLED controller IC, the module offers an SPI interface and is available with both polarizer and non-polarizer options, allowing you to select the most suitable configuration for your needs.
The WEA012840A OLED display boasts an industrial-grade operating temperature range of -40°C to +80°C, ensuring reliable performance in harsh environments. Its compact, lightweight design and exceptional clarity make it the perfect solution for gaming peripherals, networking equipment, and other devices that require high-quality, compact displays.
