Products Description

As a professional China LCD factory/manufacturer, Bolong LCD produces this 128×64 COG LCD display with full in‑house control over glass cutting, IC bonding, FPC assembly, backlight integration, and final testing. Whether you need a standard 128×64 graphic module or a fully customized version with specific outline, viewing area, interface, or temperature range, we deliver.
The 128x64 COG LCD module supports detailed graphic display, allowing engineers to design intuitive user interfaces with text, symbols, and icons. Compared with segment LCDs, it provides greater flexibility and better user experience.
We support multiple communication interfaces such as SPI, I2C, and parallel, ensuring seamless integration with different embedded systems and microcontrollers.
With mature COG bonding technology, our displays deliver excellent electrical performance, reduced failure rates, and long service life. Our engineering team works closely with customers to customize every aspect of the display, from structure to functionality.

Manufacturing strengths
The 128x64 graphic LCD module is designed as a complete display solution, integrating LCD glass, driver IC, backlight, and PCB into a single module. This reduces development complexity and ensures compatibility with customer systems.
In addition to module manufacturing, we also offer circuit board design and embedded program development, helping customers build fully functional display systems. This one-stop capability significantly shortens product development cycles and improves efficiency.
