1. Who must see the screen
If only the sidewalk matters, a single street-facing face is enough. That is WD-S.
If both sidewalk and in-store shoppers must see content through the same glass aperture, use WD-D.
Do not buy a second indoor wall screen to fix a window problem if a dual-face window stack fits the reveal.
2. Comparison table
| Decision | WD-S single-sided | WD-D double-sided |
|---|---|---|
| Audiences | Street face | Street + indoor faces |
| Depth planning | Slimmer single stack | Dual stack; confirm mm on drawing |
| Brightness class | 1500 to 3000 nits by quote | 1500 to 3000 nits by quote; faces may differ |
| Vs HS50 | Window-specialized single face | Window-specialized dual face; HS50 stays the general dual-screen hanging line |
| Detail pages | WD-S | WD-D |
3. Depth and mounting
Mullion depth kills dual-face projects more often than brightness does. Design from the millimetre depth on the quoted drawing, not from a round marketing figure.
Confirm hang points, cable exits and service access before the GC closes the glass line.
4. RFQ checklist
Send glass photos, reveal depth, target sizes, day/night brightness, whether one or two faces are required, and mount preference (hang / mullion / wall).

Frequently Asked Questions
Is WD-D the same as HS50 dual-screen?
No. HS50 is the dual-screen hanging/general line. WD-D is the window-specialized double-sided high-bright series.
Will high nits glare at night?
Use ambient light sensing and night profiles. Confirm auto-dimming on the quoted board.
Can WD-S hang from the ceiling?
Many window projects use hanging or mullion mounts. Confirm the mount kit on the quote before the GC closes the glass line.
Where is the window hub?
Start at /products/window-display/ for the category overview, then open WD-S or WD-D.
