Sharp LD-EC181 vs Unilumin UHF 1.8 (500×500)

1.8 mm against 1.8 mm · specifications from both manufacturers' datasheets

Side-by-side specifications, then the same wall built from each tile, so the comparison is in panels, kilograms, circuits and data runs rather than in marketing copy.

Whole cabinets rarely hit an identical size, so each wall is the closest build to a real video format (16:9 or 16:10) near 8 m wide for that tile: 7.80 × 4.39 m and 8.00 × 4.50 m respectively.

What the numbers say

• Both resolve to about the same density (284,444 and 291,600 pixels per square metre), so pick on weight, power or what your shop already owns rather than on image detail.
• Sharp LD-EC181 is the lighter rig: 21 kg/m² against 24 kg/m². Across this wall that is 172 kg of difference, 892 kg versus 1,064 kg, which moves point loads and can change the hoist call.
• Unilumin UHF 1.8 (500×500) draws more: 500 W/m² against 252 W/m² at full white. For this wall that is 8.6 kW versus 18 kW, and 4 versus 8 circuits at a 16 A/230 V supply with an 80% derate.
• Data is lighter on Sharp LD-EC181: 26 runs against 32, at 9 and 7 panels per port respectively (60 Hz, 8-bit, ports loaded to 80%). Fewer runs means fewer home runs to pull and fewer processor ports to find.
• Different cabinet formats: 600 × 337.5 mm against 500 × 500 mm, so 169 tiles versus 144 for the same wall. Fewer, larger cabinets build faster; smaller ones give finer control over wall dimensions and are easier to handle alone.
• Estimated truck space: 6.5 m for Unilumin UHF 1.8 (500×500) against 7.3 m for the other, including spares, cases and cabling.
