How to Specify an Indoor COB LED Display – COB vs SMD, Pixel Pitch Selection, and the Costs Buyers Overlook

COB vs SMD – What Actually Changes

COB and SMD solve the same problem in different ways. SMD mounts individual LED packages onto the board surface. COB bonds the chips directly to the board and covers them with a protective layer. The practical differences appear in three areas.

Surface smoothness. COB produces a flatter surface, which reduces glare and improves appearance at close viewing distances. This matters in control rooms and conference rooms where the screen is viewed from a few meters.

Physical protection. The COB surface resists contact damage better than exposed SMD packages. In rooms where the display is within reach of occupants, this reduces the risk of dead pixels from accidental contact.

Contrast. COB typically produces higher contrast than SMD at the same pitch, because the surface reflects less ambient light.

Pixel Pitch Selection – Work Backwards From Viewing Distance

The correct sequence starts with viewing distance, not pitch.

Pixel Pitch	Comfortable Indoor Viewing Distance	Typical Use
P0.78	1–2.5 m	Control room, close data review
P0.93	1.5–3 m	Control room, broadcast studio
P1.25	2–5 m	Conference room, showroom
P1.56	3–6 m	Boardroom, lobby

Choosing a finer pitch than the room requires adds cost without visible improvement. Choosing a coarser pitch than the viewing distance allows produces visible pixel structure.

The 16:9 Cabinet and Why It Reduces System Cost

A 600×337.5mm cabinet matches standard video aspect ratio. This means the display does not require content reformatting or letterboxing, and the pixel count maps directly to 2K, 4K, or 8K standards. In systems where content is produced in standard formats, this reduces integration work and avoids the scaling hardware that non-16:9 cabinets often require.

Front Service and the Hidden Rear Access Cost

A display that requires rear access needs either a service corridor or a mounting method that allows the screen to swing away from the wall. Both add cost. The 600 Series uses full front service with an electric vacuum clamp, so modules can be replaced from the front. On retrofit projects, this often determines whether a wall-mounted installation is feasible.

The Weight and Depth Variables

A 30mm cabinet at 5.1kg allows wall mounting on structures that cannot support deeper or heavier displays. On retrofit projects, the weight and depth often determine feasibility more than pixel pitch. Confirm the wall structure and mounting method before finalizing the specification.

Questions to Ask Every Indoor LED Supplier

Is the pixel pitch matched to the actual viewing distance, or chosen for marketing?
Does the cabinet match 16:9 native, or does it require content scaling?
Is maintenance front-access only, or does it require rear clearance?
What is the cabinet weight and depth, and what mounting does it allow?
What is the contrast ratio at the specified pitch?
What resolutions are achievable through splicing, and at what cabinet count?
What is covered under warranty, and what is excluded?
