Distance de vision et pas de pixel en façade

Calculez le pas angulaire, la résolution réelle et la capacité de contrôle avant de choisir des tubes pixel.

Méthode de calcul

• Viewing zones → content class → true grid → control and power → full-scale mock-up.
• θ = 2 × arctan(p ÷ 2D); treat the result as a comparison input, not an acceptance guarantee.
• 24 m × 12 m at 250 mm × 500 mm spacing = 97 × 25 = 2,425 pixels.
• RGB direct-channel model: 15 DMX-equivalent universes; RGBW: 19. Verify the actual controller mapping [S3].

Preuves produit

LIKELIGHT publishes a P16.67 cm RGBW aluminum pixel-tube reference [S1] and a 55 mm/custom transparent-grid reference [S2]. Exact IC, port capacity, wiring, power injection and failure behavior remain project approval items.

Quand ne pas choisir

Do not copy direct-view display rules blindly. Do not promise text or detailed video on a 97 × 25 canvas. Do not approve pitch without representative content and a night mock-up.

FAQ

Universal formula? No; angular pitch is only one input.

Author? 待确认. A verifiable expert name, position and profile link must be added before publication.
