The table shows the standard build for this P4 Indoor LED Billboard. Cabinet size, brightness and control system can be changed per project; the final datasheet is issued with the PI before production. Cabinets are tested against IEC 60068 for temperature, humidity and vibration.
How the numbers work on a real wall
To size this P4 Indoor LED Billboard, start from whole cabinets: a 4×3 build gives a 3.84×2.88 m screen, 960×720 pixels (0.69 MP), about 367 kg of cabinet and an average load near 3,300 W. Add one row and the same cabinet family gives 3.84 m height with no new tooling, which is why projects usually fix the wall size first and the pitch second.

Installation and service access
Billboards are engineered as a steel structure: the cabinet array is fixed to a hot-dip galvanised frame and the control cabinet sits in a weatherproof enclosure at the base. We provide the structure drawing, wind-load notes and the power distribution plan.
Automatic brightness sensors are included so the screen dims at night and stays within local light-pollution rules. 3-year warranty on modules, power supplies and receiving cards; spare parts held in Shenzhen for five years after the order.
P4 Indoor LED Billboard: frequently asked questions
Can I see this LED display running before I order?
Yes. We send a video of the exact cabinet type under a white and a grey test pattern, plus a phone camera pan, so you can judge scan lines and uniformity before the deposit.
What does the 3-year warranty cover?
Modules, power supplies, receiving cards and the cabinet structure. Wear parts such as fan filters are excluded, and spare parts stay available in Shenzhen for five years after the order.
Can you put our brand on the P4 Indoor LED Billboard?
Silkscreen on the 960×960 mm cabinet, a branded carton and a custom manual are included from 50 m²; below that we print labels only, so the MOQ stays at one square metre.
Will this P4 Indoor LED Billboard survive a coastal or high-humidity site?
Yes, with the coastal option: epoxy coating on the cabinet, stainless screws, conformal-coated driver boards. Humidity above 85% year-round is the case where that option pays for itself.
