Who Should Choose Block
Block is the size tool. If the wall opening is the problem — not the pixel technology — start here. If the left column is your job, stay. If the right column is your job, leave this page.
- ✓ Awkward openings — mix 500 / 750 / 1000 mm cabinets so the wall hits the dimension without a custom cabinet
- ✓ Churches and halls — P2.5 to P3.91 at typical seating distance, front service on a sealed wall
- ✓ Lobbies and receptions — P1.56 to P1.95, 33 mm depth, 9.8 kg per cabinet
- ✓ Retail and education — GOB face, indoor IP31, walk-up viewing
- ✓ 90° corners or dual-sided walls — rotate the cabinet; optional dual-side; stock cabinets, not corner modules
- ✓ Flush commercial walls — front service, no 600 mm rear corridor
- ✗ Under 2 m or 24/7 control rooms — Fine Pitch / COB Pro
- ✗ Plug-and-play 16:9 rooms — All-in-One LED TV
- ✗ Portable single units — LED Poster
- ✗ 500 mm curve + heavier structure — Brick Series
- ✗ Column wrap — Flexible Series
- ✗ Rental touring — Matrix 500
- ✗ Outdoor — Square 1000

Four Cabinet Sizes — 33 mm DeepA Size Tool, Not a Pitch Story
Most indoor walls fail the tape measure before they fail the pixel. Block exists so you can fill 3,250 mm or 2,750 mm with stock cabinets instead of a custom box.
The job Block is built for: the architect gave you a wall that is not a multiple of 500 mm. You mix 500×250, 750×250, 1000×250, and 1000×500 mm on one elevation. A 3,250 mm opening is two 1000 mm cabinets plus one 750 mm and one 500 mm. Leftover: zero. No custom extrusion. No waiting on a one-off die.
Inside the cabinet the hub is cable-less — power and data through board connectors, not a harness of ribbons. Cabinets rotate 90° for portrait or landscape. Dual-side is an option for a totem or a room divider. Service is from the front: pull a module off the face. The Shenzhen Triple-Fold reception used 98 stock cabinets and Block back-mount brackets — no welded steel on site.

Six Decisions That Make Block the Size Tool
What the cabinet actually does on a commercial wall — and what that means for the bid.
500 / 750 / 1000×250 and 1000×500 mm — Hit the Opening With Stock
Every pitch uses the same four cabinets: 500×250×33, 750×250×33, 1000×250×33, and 1000×500×33 mm. Mix them on one elevation. A 3,250 mm wall is 1000 + 1000 + 750 + 500. A 2,750 mm wall is 1000 + 1000 + 750. Height stacks in 250 mm steps; two 250 mm cabinets sit beside one 1000×500. You do not wait on a custom die for a leftover 250 mm.
33 mm Thin, 9.8 kg — Same Number on Every Size
Depth is 33 mm across the four cabinets. Weight is 9.8 kg across the four cabinets. Aluminum die-cast, indoor IP31 front and rear. A 1000×500 cabinet and a 500×250 cabinet use the same load figure on the structural drawing. The Shenzhen Triple-Fold reception hung 98 cabinets on Block back-mount brackets — no welded steel frame on site.
Cable-less Hub — Power and Data on the Board, Not in a Harness
Block cabinets use a cable-less hub: module power and data seat on board connectors. You are not dressing a bundle of ribbons behind a 33 mm cabinet. Fewer connectors means fewer loose pins after a truck ride and a faster first-light. Control is Novastar or Colorlight. Inputs: DVI, HDMI, SDI, AV, DP, VGA, YPBPR. Mains: 90–264 V AC.
GOB Is Standard — Not an Upgrade Line on the Quote
Glue-on-board resin covers the SMD lamps on every Block module. Churches, schools, and retail floors hit the wall with bags, mops, and fingers. GOB is still SMD — it is not COB — but it stops the common indoor failure: a dead lamp from a cleaning rag. Contrast is 5000:1. Refresh is 3840 or 7680 Hz. Grayscale is 16-bit. Viewing angle is 160° H / 160° V.
Rotate 90° or Run Dual-Side — Stock Cabinets, Not Corner Modules
The same cabinet rotates 90° so the 250 mm module grid runs landscape or portrait. Dual-side is an option when both faces of a totem or a room divider need content. 90° corners use standard cabinets — the Shenzhen Triple-Fold reception held 0.5 mm at the folds with 98 stock cabinets (70 × 1000×500 and 28 × 500×250), no custom corner modules.
Front Service — Pull the Module Off the Face
Modules come off the front. No rear corridor. No opening finished drywall behind a lobby or a sanctuary wall. The module is 250×250 mm on every pitch, so a spare from a 500 mm cabinet seats in a 1000 mm cabinet. A technician stands in the aisle. Rear-access cabinets need about 600 mm behind the wall; most commercial interiors do not have it.
Where Block Goes on the Wall
Churches, halls, lobbies, retail, and classrooms. Not a control-room flagship — if operators sit under 2 m, use Fine Pitch.
Churches and Assembly Halls
Seating 6–20 m. Specify P2.5 to P3.91. Lyrics and IMAG stay sharp without paying for unused density. Front service on a sealed sanctuary wall. Read the church LED guide.
Lobbies and Reception Walls
Walk-up 2–5 m. Specify P1.56 or P1.95. 33 mm depth and 9.8 kg keep the back-mount light. Mix cabinet widths when the architect's opening is not a 500 mm multiple. Documented job: Shenzhen Triple-Fold, P1.953, 38.5 m².
Retail and Brand Floors
GOB face for a floor that gets touched. 600 or 800 nits by pitch. Front service after hours from the aisle. Dual-side option for a totem in the circulation path. 90° rotate for a portrait end-cap.
Lecture Halls and Classrooms
P2.5 to P3.91 at lecture distance; P1.95 if students sit close. Front service so the university does not open the wall during term. Same 250×250 mm spare across cabinet sizes. IP31 indoor only.
