In short · what does retail use Smart Film for?
There are 3 main use cases where luxury retail uses Smart Film:
- (1)Display Window — storefront glass that stays clear during opening hours and opaque after closing or during a display change
- (2)Private Viewing Room for VIP customers who want privacy
- (3)Cinematic Display that turns opaque to become a screen for a projector to play the brand story · most use PNLC (reverse mode) as the core technology
Price 6,700-14,800 THB/sqm.
3 use cases · Luxury Retail
1. Display Window · storefront glass
PNLC clear by default · opaque on demand · saves more power
Jewelry and luxury watch shops run their display window around 12-15 hours a day, so it needs to stay clear all day and go opaque only for closing, a display change or window cleaning — and PNLC saves noticeably more power than PDLC, because PDLC has to keep the power on all day to stay clear.
Budget: large pane 8-15 sqm × 9,500 THB ≈ 76,000-142,000 THB
2. Private Viewing Room · VIP Lounge
PDLC · opaque by default · clear when hosting a VIP
Luxury car showrooms (such as Porsche · Maserati · Ferrari), high-end watches like Patek or Rolex, and most jewelry houses have a private lounge for VIP customers, where the glass partition is opaque by default and turns clear when a VIP is invited in — delivering a luxury-experience UX that outclasses the competition.
Budget: 8-12 sqm × 8,500 THB ≈ 68,000-102,000 THB
3. Cinematic Display · Brand Story
PNLC · clear as glass · opaque as a projector screen
The storefront glass is clear by default to display the products; when an event begins or at minute zero of the day, the glass instantly turns opaque while a projector plays the brand story, so passers-by see viral content. It's a cinematic-display trick that luxury brands like Hermès · Dior · Tiffany already use widely.
Budget: 6-10 sqm × 9,500 THB ≈ 57,000-95,000 THB + projector
Performance + Lucida™ · the clearest for luxury display
The problem with standard PDLC in a display window is a slight haze when clear, whereas luxury jewelry/watch products demand maximum clarity, so Performance + Lucida™ reduces haze several-fold, nearly indistinguishable from bare glass — ideal for premium luxury display.

Frequently asked questions · Luxury Retail
Where can a luxury car showroom use Smart Film?
There are generally 3 key spots —
Is Smart Film worth the investment for a watch or jewelry shop?
Very much so, especially for a shop in a luxury mall whose display window must run 24/7 · PNLC saves power (no need to keep the power on to stay clear all day) while Lucida™ makes the glass as clear as possible to display products · a budget of about 70,000-150,000 THB per window · it adds a USP that attracts premium customers · and pays back the luxury-mall rent quickly versus the competition.
Can the display window be set to go opaque immediately after closing?
Yes · use schedule auto-tint via the Smart Office Hub · set it, for example, to frost automatically at 22:00 · and return to clear at 09:00 · no need to do it by hand · it integrates directly with the mall's BMS · InHouse specs the integration free of charge in the installation package.
Is it worth it for a small boutique (window about 4 sqm)?
Worth it if it's a luxury brand · a budget of about 40,000-50,000 THB per window · use PNLC + Lucida™ to display products as clearly as possible · going opaque after closing prevents late-night window shopping and stops people secretly photographing the display behind the glass.
How does a Cinematic Display + projector work?
The PNLC glass stays clear 90% of opening hours · with a ceiling-mounted projector aimed at the glass throughout · when you want a "show" → the glass turns opaque and the projector image appears crisp · it's a visual trick luxury brands use to draw in passers-by · read a similar use case at → Café Projector Branding
Do Tier 1 brands (Hermès · Dior · LV) use Smart Film in Thailand?
It's already used abroad, e.g. Hermès Paris · Dior Tokyo · LV Champs-Élysées · in Thailand, some brands in Bangkok's luxury malls (Central Embassy · ICONSIAM · EmSphere · Siam Paragon) already use it · InHouse specs Lucida™ grade with custom colour for luxury projects specifically · see cases we've done → Portfolio Mega Projects
PDLC or PNLC for a showroom — which should you pick?
For a display window running 12-24 hours a day, PNLC (reverse mode) is better because it's clear throughout opening hours and opaque only when closed · for a private viewing room, choose PDLC, which is opaque by default and clear when a VIP is invited in · read the full technology comparison at → PDLC vs PNLC · full technical comparison
Do you need mall permission to fit Smart Film on a luxury-mall storefront?
Yes · always get mall permission before starting work · most luxury malls in Bangkok (Central Embassy · ICONSIAM · EmSphere · Siam Paragon) allow it because they see it as a premium upgrade to the space · InHouse provides the spec documents + reference images free of charge to make the permit application easy to manage.
