Should You Use Point Lights or an LED Screen on a Facade?

Summary: Pixel point lights and LED screens solve different facade problems. A screen is a continuous pixel surface — it wins when viewers are close and content is detailed video, but it adds a solid plane that blocks light, catches wind, and needs substructure. Point lights are individually addressed fixtures mounted directly on the structure — they win when the building must stay open (high transparency), the structure cannot carry a frame, wind-load review is tight, or the design is dot-matrix rather than detailed video. Both can carry video from a distance: INMU has delivered 700,000 individually addressed points in Beijing Wangjing, and also 1,400 m² of P10 LED film at close range in Beijing. The decision is made by viewing distance, structure, and content type — in that order.

The Short Answer

• Choose an LED screen when viewers stand within roughly 15–30 m and content is detailed advertising video — text, product shots, full-motion imagery. A continuous pixel surface is what reads at that distance (INMU's 1,400 m² P10 film installation at Beijing Wukesong Wanda Plaza is exactly this case).

• Choose pixel point lights when the facade must stay visually open, the structure cannot accept a frame, wind-load review is strict, or the content is artistic dot-matrix and flowing effects. Points mount individually and add almost no wind face — the reason a bridge project in Taiyuan used 30,000 points after solid panels failed structural review.

• Both carry video from a distance. At 100 m+, a well-planned point grid reads as video — the Wangjing facade runs 700,000 individually addressed points on DMX512. The difference shows up at close range, where a point grid reveals its spacing and a screen does not.

• Hybrid is normal. Many facades run a screen on the retail podium (close viewing) and points on the tower above (distance, wind, and openness).

The Five Differences That Matter

1. Surface versus scatter. A screen is a continuous plane of pixels at a fixed pitch — fine detail survives close inspection. Point lights are individual fixtures on a grid you define; the surface is optically "open" between points. Everything else follows from this.
2. Transparency and daytime appearance.A solid screen covers the facade (and blocks daylight behind it); a point grid leaves the building visible. This is usually what planning authorities care about — and what occupants care about, since a screen can turn a window wall into a dark one.
3. Structure, weight, and wind.Screens require a substructure and present a full wind face; cabinets with steelwork commonly run 30–50 kg/m². A point is a small body mounted to existing structure — grams per point instead of kilograms per square meter, and a fraction of the wind area. On towers and bridges this is often the deciding factor, not the image.
4. Content range.Screens excel at fine video, small text, and photographic content. Point lights excel at flowing effects, chases, dot-matrix graphics, and large-scale video viewed from distance — a grid at 100 mm spacing will not render a logo as crisply as a P10 screen at 10m.
5. Maintenance model.Screens are serviced per module or cabinet; points are serviced per point. On accessible facades modules are faster to swap; on high, difficult structures, a failed point is unplugged and replaced individually (IP65–IP67 sealed, snap-access bodies) without dismantling a panel run.

Point Lights vs. Screens at a Glance

What 18 Years of Both Types Taught Us

INMU has manufactured both point lights and screens since 2008, with products used at the Hangzhou G20 Summit, CCTV Spring Festival Gala 2017, Qingdao SCO Summit, Wuhan Military World Games, and the 100th Anniversary celebrations. Documented projects on both sides of this comparison:

• Beijing Wangjing — 700,000 points on DMX512, 16-bit. A point grid at a scale where it reads as a media surface — proof that "points don't do video" is a myth at distance.

• Beijing Wukesong Wanda Plaza — 1,400 m² at P10. Close, plaza-level viewing justified a fine-pitch screen; a point grid at that distance would have shown its spacing.

• Taiyuan Bridge — 30,000 RGBW points. Solid screen panels could not pass wind-load review; point hardware on the existing structure could. The structure chose the system.

• Tianshui Stadium — 200,000 points. Long-throw reading across a stadium bowl, serviced zone by zone.

The rule that emerges: distance decides detail, structure decides type. Fix the viewing distance first, then let the building's structural and daylight constraints pick the system.

Common Mistakes

• Buying a screen where the structure will object. Cabinets on a bridge or a lightweight tower can fail review outright; points installed on the existing structure usually pass. Check structural feasibility before falling in love with a pitch.

• Buying points for close-range video. Below ~15–20 m, a point grid's spacing becomes visible and the content looks coarse. If the brief includes small text at street level, that is a screen.

• Comparing the two on transparency alone. Film and mesh screens also deliver 60–90% transparency. The real point-light advantages are per-point mounting, minimal wind face, and no substructure — not transparency per se.

• Forgetting daylight. A solid screen behind occupied glazing darkens interiors during the day. Points and transparent films keep windows working.

• Assuming one system per project. Podium screens plus tower points is a standard, cost-effective combination — and both can run on the same DMX512 control universe (see our remote control guide).

Frequently Asked Questions

Q1: Can point lights display real video? Yes, viewed from distance. At 200 mm spacing and beyond ~30–50 m viewing, a point grid plays flowing video and large graphics — as demonstrated by a 700,000-point facade in Beijing. For fine detail at close range, a screen is the correct tool.

Q2: How close can viewers get before a point grid looks coarse? Depends on spacing: at 100 mm spacing a grid reads cleanly from roughly 30 m; coarser grids need more distance. Fix spacing from the closest realistic viewing point (see How Many LED Pixel Points Do You Need for a Building Facade?).

Q3: Which is cheaper for a large facade? Points are usually cheaper per square meter on coarse grids because there are fewer emitting units, no substructure, and less steel. On very fine grids the cost advantage can reverse — which is why density, not product category, drives budget.

Q4: Which is easier to maintain on a high-rise? Points: a failed unit is unplugged and swapped individually during a scheduled access visit, with IP65–IP67 sealing keeping failures rare. Screen modules are efficient to swap on accessible facades but heavier to handle at height.

Q5: Can point lights and screens share one control system? Yes. DMX512 is common to architectural and stage lighting, and INMU screens run standard control ecosystems — so a facade can synchronize a tower-point surface with a screen below (see Comparing LED Pixel Point Light Solutions).

Q6: When should I definitely choose a screen instead? When the brief includes fine text, product imagery, or detailed video viewed closer than about 20 m — or when the mounting surface is a flat storefront or podium where structure and wind are not constraints.
