Customized Non-Standard COB Modules

Fully Custom Non‑Standard COB Modules are designed for products that cannot use off‑the‑shelf displays. Unlike standard modules with fixed dimensions, resolutions, and interfaces, our custom COB (Chip‑on‑Board) modules are built from the ground up to your exact specifications – from the glass layout and PCB shape to the driver IC and connection method. As a professional China COB manufacturer, Bolong LCD leverages two integrated divisions: one for LCD glass (pen‑segment, graphic, character) and another for PCB design, circuit assembly, and embedded firmware. This vertical integration allows us to deliver a complete, ready‑to‑install COB module that matches your product's mechanical envelope, electrical interface, and environmental requirements.

Complete Mechanical Freedom
We design the PCB from a blank slate – any shape, any mounting hole pattern, any connector location. Your enclosure no longer needs to accommodate a standard module; the module fits your enclosure perfectly.

Any Resolution, Any Pixel Count
Need 100×32 240×160? 128×48 We design the glass mask and select the appropriate driver IC. No wasted pixels, no unnecessary glass area.

Rugged COB Construction
The driver IC is wire‑bonded to the PCB and encapsulated in black epoxy. This protects against moisture, dust, and vibration – ideal for industrial and medical environments. COB is more rugged than COG .

Integrated Electronics – Reduce BOM Complexity
We can add on‑board components: MCU, level shifters, backlight driver, ESD protection, even a real‑time clock. Your main board only needs power and a simple serial connection.

Long Lifecycle Support
We retain your PCB Gerbers, glass mask tooling, and firmware source code for a minimum of 10 years. Repeat orders are easy – no re‑engineering, no unexpected EOL.

Factory Direct – One Supplier, One Responsibility
From glass manufacturing to PCB assembly to firmware programming – all under one roof. You deal directly with the factory, not a broker.

These customized non-standard COB modules support customization of ultra-small dimensions, low power consumption and special pin layouts, suitable for portable fitness equipment, handheld medical devices, portable measuring tools and IoT terminals. With compact structure and reliable performance, they save space in portable products while ensuring stable display effect.
