Distancia de visión y pixel pitch en fachadas
Distancia de visión y pixel pitch en fachadas
Calcule el paso angular, la resolución real y la capacidad de control antes de especificar tubos pixel.
Método de cálculo
- 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].
Evidencia de producto
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.
Cuándo no elegirlo
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.
