HUA XIAN JING offers a broad range of COG monochrome LCD modules, from compact 16×2 and 20×4 formats to large COG LCD panels such as 128×64, 132×32, 240×128, and 240×160. While COG and COB refer to different packaging techniques, we continue to deliver rugged LCD modules featuring slim profiles and low power consumption. Enhanced options include wide operating temperature ranges, sunlight-readable displays, salt-fog resistance, and high-altitude operation to suit demanding environments.
Hua Xian Jing is a manufacturer specializing in small and medium size LCD module, our product size ranges from 0.32 inch – 10.11 inch, and provide ODM/OEM service. Our factory specializes in B2B services, including factories, LCD suppliers, etc. We only provide wholesale service.
Contact us for specific MOQ.
Just tell us what you want, we can select the product that meets your requirements from 10000+ standard products.
Based on 14 years of experience, our engineers have designed and generated a large number of LCD module prototypes for our customers, when you tell us your product and requirements, we can quickly design LCD module prototypes for you.
The maximum time for our engineers to design the prototype is less than 7 days!
Our products have passed ISO 9001 quality certification and IATF16909 certification for automotive assemblies. If your product is in a special industry (eg: medical, aerospace, marine) that requires established industry certification, we will be able to apply for certification for your product.
We provide professional after-sales service. You don’t need to worry about the docking problem of LCD module and your product, we can communicate with your engineers directly to solve the technical problems quickly.
It usually takes about 7–10 days to create the samples, and around 30–45 days for full production.
It depends on the size of your COG LCD, but usually, the minimum order is around 1,000 units.
Absolutely! HUA XIAN JING’s factory can add your company logo and icons using silk-screen printing.
We support both air bonding and optical bonding. For standard monochrome COG LCDs, we typically use air bonding.
Yes, we are! HUA XIAN JING is ISO 9001 certified, and our LCD modules also meet IATF 16949 automotive and IEC 60601 medical certifications.
Almost everything can be customized — size, backlight color, interface, number of pins, communication protocol, IC, and more.
If you’ve got a design drawing for your COG LCD module, just send it over. If you’re still designing, let us know your product needs—the more details, the better!
Just contact your sales, and they’ll connect you with our engineers who can help you out.
Sorry, we don’t do small-batch customization. We’re a manufacturer focused on providing bulk LCD module ODM/OEM services for wholesalers and factories.
Pricing is influenced by components like ICs and glass substrates. If you’re placing a large order, we can offer better pricing accordingly.
Engineered for extreme conditions – powering 50+ global electric vehicle with displays that deliver crystal clarity even under direct sunlight.
Core Advantages You Can’t Ignore:
Sunlight Readability: High brightness (500-1000 nits)
Wide Temperature Range: Typically -30°C to +80°C
Vibration Resistance: Meets IATF16949 standards
Low Power Consumption: 3.3V/5V operation
Compact Design: Ultra-thin profile (often <3mm)
Most portable devices (e.g., remote controls, multimeters, calculators) operate at 3.3V or 5V to extend battery life. In response to customer feedback, we have optimized our compact LCD modules to work seamlessly with these voltages.
This adjustment simplifies integration, eliminates the need for voltage conversions, and reduces development steps for end-product designers.
Why Engineers Choose Us:
COG (Chip-On-Glass) LCDs offer significant advantages over COB (Chip-On-Board) LCDs:
These benefits make COG LCDs ideal for portable and handheld devices:
The 128×64 resolution is our most popular dot-matrix COG LCD module. We also offer customized formats including 128×32, 132×32, 192×64, and 240×160 to match diverse product needs. Share your project’s expected production volume for tailored solutions.
Note: Custom pixel configurations require higher minimum order quantities (MOQs).
In our 13 years of experience in LCD ODM/OEM services, there are few such cases. Enterprises often suffer from the discontinuation of raw materials for LCD, and Hua Xian Jing is the source manufacturer of LCD, we can also quickly find a replacement in the face of raw material discontinuation.
For the replacement of existing LCD products, we need you to provide at least one of the following information:
Note: Whether you are replacing an existing LCD or customizing a new LCD module, you will need to meet our minimum order quantity.
According to lab data, the Mean Time Between Failure (MTBF) of HUA XIAN JING LCD modules is 50,000 – 70,000 hours, which is about 5.4 – 8 years. However, the life expectancy of a TFT LCD is usually affected by temperature, usage environment, and human damage. Of course, we do offer a 1-year warranty to protect the quality of our products.
Over the years, rich experience in LCD module generation has led us to accumulate 10,000+ standard LCD modules in our standard library, download our catalog to select the LCD module that best suits your needs!
