Before you buy parts, work out how many modules and cabinets the screen needs, what resolution it will have and how much power it will draw. Here is a worked example you can follow with your own numbers.
Example: a 3.2 × 1.92 m indoor P2.5 screen
1. Modules
A P2.5 module is 320 × 160 mm. Across: 3,200 ÷ 320 = 10 modules. Down: 1,920 ÷ 160 = 12 modules. Total: 10 × 12 = 120 modules.
2. Resolution
Each P2.5 module is 128 × 64 pixels. Width: 10 × 128 = 1,280 px. Height: 12 × 64 = 768 px. The screen is 1,280 × 768 pixels, a little under one million pixels in total.
3. Cabinets
With 640 × 480 mm indoor cabinets (2 × 3 modules each): 3,200 ÷ 640 = 5 across and 1,920 ÷ 480 = 4 down, so 20 cabinets. Screen sizes work out neatly when they are multiples of the cabinet size, so it is worth adjusting the size slightly to fit.
4. Power
Qiangli rates its Q2.5-32S indoor modules at up to 24 W each. 120 × 24 W = 2,880 W maximum. Qiangli's datasheets give average consumption as about one third of maximum, so expect around 960 W in normal use. Size the power supplies from the module's datasheet table and keep spare margin (see how many power supplies).
5. Control
About 983,000 pixels fits within one video processor such as the Colorlight X7 (5.2 million pixels) and needs two Gigabit outputs at about 650,000 pixels each. Plan one receiving card per cabinet.
Your checklist
- Screen width and height (round to the cabinet size)
- Pixel pitch and indoor or outdoor module
- Number of modules and cabinets
- Resolution and processor outputs
- Maximum and average power, number of power supplies
- Receiving cards, cables, magnets or screws, and spare modules (many installers keep a few percent spare from the same batch)
