Transparency is a site condition, not a headline
Transparency describes how much of the view passes through the screen. On a shop window it protects the window display. On a facade it protects the architecture. On a stage it keeps performers visible.
The useful question is not which product has the highest percentage, but how much of the view must remain after the screen is installed. That answer sets the minimum open area.
Pitch should follow viewing distance
Pixel pitch sets the smallest detail the screen can show. A fine pitch is wasted if the nearest viewer stands twenty metres away, and a coarse pitch becomes visible as pixels when the audience is close.
Match the pitch to the closest meaningful viewing distance, then confirm the content type. Text and product detail need more resolution than abstract motion graphics.
- Close interior viewing: finer pitch, lower brightness
- Street-level frontage: medium pitch, higher brightness
- Large facade viewed from distance: coarse pitch, high brightness
Brightness is a range, not one number
A screen that is bright enough at noon may be painfully bright at 10pm. Specify both the peak brightness and the dimming range, and confirm how the screen responds to ambient light.
For outdoor sites, local night-time limits may also apply. A dimming schedule is part of the design, not an afterthought.
Where the balance usually lands
Retail windows generally accept a higher pitch and lower brightness because the viewing distance is short and the interior light matters. Facades move in the opposite direction.
Write the three values down together for each elevation or window, and check them against the content plan. A specification that is right for the atrium may be wrong for the street entrance.
