COB LED Display Module

A COB LED display module mounts bare LED chips directly on a printed circuit board and seals them beneath a protective layer. EagerLED supplies fine-pitch COB LED modules from Shenzhen, China, for indoor video walls in conference rooms, control rooms and broadcast studios.

COB LED Packaging Technology

COB stands for Chip on Board. Unlike SMD modules, which use individually packaged LEDs mounted on a PCB, COB modules place bare LED chips directly on the board and encapsulate them together. The resulting flat face helps protect the small chips during handling and supports fine pixel spacing.

In flip-chip COB construction, the chip electrodes face the PCB. This avoids conventional wire bonds at the chip connection and provides a direct path for heat transfer. The complete screen still needs suitable power supplies, ventilation and thermal design. Confirm the packaging type for the selected model.

Smooth, High-Contrast Image Quality

A fine-pitch COB LED screen can display detailed text, graphics and video at short viewing distances. Surface treatment, black level, brightness and calibration all affect the visible contrast and color uniformity. COB packaging alone does not guarantee identical image quality across different modules.

For meeting rooms, assess small text at the nearest seat and at normal room brightness. For broadcast studios, test the proposed refresh rate and scan configuration with the camera frame rate and shutter settings to check for banding.

COB LED Display Module Protection and Maintenance

The encapsulated face helps protect the LED chips from dust, moisture and incidental contact. Handle modules carefully and use the approved cleaning method; surface protection does not make a panel impact-proof or suitable for every outdoor environment.

Plan service access and compatible spare modules before installation. A COB repair may require specialist equipment or module replacement, so confirm the repair procedure, calibration requirements and warranty coverage when ordering.

Fine-Pitch COB LED Modules for Indoor Video Walls

EagerLED lists fine-pitch options including P0.62, P0.78, P0.93, P1.25 and P1.53. A smaller pixel pitch places more pixels within the same display area, which can improve detail for nearby viewers. Select the pitch for your content, nearest viewing distance and budget.

A module is one building block of the screen; it is not a complete 4K or 8K display. Native resolution depends on the total pixel count across the assembled wall. Calculate screen width in pixels as modules across multiplied by each module’s horizontal resolution, and calculate height the same way. Check the processor and receiving-card capacity for that layout.

How to Choose a COB LED Display Module

Use the specification tables to compare the available models. A 320x160mm COB LED display module and a 150 x 168.75 mm module require different cabinet layouts; matching pixel pitch alone does not make them interchangeable.

Mechanical fit: check module dimensions, mounting points, cabinet flatness and front or rear service access.
Electrical compatibility: confirm voltage, power demand, connector pinout, scan mode, receiving card and configuration file.
Image performance: compare module resolution, brightness, refresh rate and calibration at the intended operating settings.
Replacement orders: send front and rear photographs, the module label and controller details. Confirm batch and color matching before mixing modules.

Request the COB LED display module datasheet, connection drawing and installation instructions for the exact model. Compare other technologies in our LED display module range.

COB LED Module Supply from Shenzhen, China

EagerLED is based in Shenzhen and supplies LED display products for international projects. For installations in the United States, India, Germany or another market, include the destination country and city in your inquiry. Ask the team to confirm applicable compliance documents, local electrical requirements, shipping terms, lead time and the spare-parts plan for your order.

For a custom screen layout, provide the required dimensions, target resolution, installation drawings and service access. Confirm module availability and cabinet compatibility before finalizing the design.

COB LED Display Module FAQ

01. What is a COB LED display module?

A COB LED display module is a circuit board with bare red, green and blue LED chips mounted directly on it and sealed under a protective layer. Several modules are assembled with cabinets, power supplies and control electronics to create a COB LED video wall. These display modules are different from COB lighting strips or white-light lamp modules.

02. What is the difference between COB, SMD and GOB?

SMD uses individually packaged LEDs mounted on a board. COB mounts bare chips directly on the board and encapsulates them together. GOB adds a protective coating to an assembled LED surface, often an SMD module. Compare pixel pitch, image quality, protection, service method and total system cost. See our GOB LED display modules for the alternative coating approach.

03. Which pixel pitch and module size should I choose?

Choose pixel pitch for the nearest viewers, content detail and target screen resolution. Then select a module size that fits the cabinet layout. Compare the 320 x 160 mm and 150 x 168.75 mm series above, and confirm the exact model, resolution and mounting dimensions with EagerLED. A smaller pitch is useful for close viewing but is not automatically the best choice for every budget.

04. Can COB LED modules make a 4K video wall?

Yes, when the assembled modules provide the required native pixel count and the control system supports it. For UHD 4K, plan for 3840 x 2160 pixels across the complete screen. A single module is not a 4K display, and playing a 4K input does not increase the physical resolution of a lower-resolution wall.

05. What determines the COB LED display module price?

Price depends on pixel pitch, module size, chip and driver specification, calibration, quantity and accessories. Send your preferred model or screen dimensions, application and destination for an itemized quote. Confirm whether power supplies, receiving cards, cabinets, spare modules, freight and import charges are included.

06. Can I replace an SMD module with a COB LED module?

Only after checking compatibility. Match the dimensions, mounting points, pixel resolution, voltage, connectors, scan mode and receiving-card configuration. Surface appearance and color calibration can differ, so a same-size COB module is not necessarily a drop-in replacement for an SMD board.

07. Are these COB LED modules suitable for outdoor use?

This range is presented for indoor display applications. Encapsulation helps protect the LED face, but it does not establish the weather resistance of a complete screen. For an outdoor project, request a model and cabinet with documented protection ratings, brightness and operating limits suitable for the site.

08. How do I request a datasheet and an international quotation?

Provide the module model or screen dimensions, quantity, viewing distance, content type, destination country and city, and required delivery date. Ask for the model-specific datasheet, wiring and control requirements, warranty terms, compliance documents and shipping quotation. For an existing screen, also send module-label photos and the current control configuration.
