About us

The factory behind the film

Shenzhen Jiexinhui Technology Co., Ltd. manufactures PDLC smart film and switchable privacy glass in-house in Shenzhen: from ITO roll-to-roll coating to finished, wired panels. No middlemen, no outsourced coating.

Our core values

A manufacturer, not a trading company

Patented liquid crystal formula - up to 92% transmittance, developed by our R&D team
Dust-free, thermostatic workshop - prevents haze and defects in any climate
Every piece power-on tested - checked at 60V for sparking, delamination and white spots before packing
Engineer-led sales - the person quoting you supports your installation
Factory visits welcome - Longgang, Shenzhen. Warmly welcomed, as our guide says

Our film, doing its job

A window wall fitted with SGV smart film switching between view and privacy.

Under 0.1 s switching - clear to frosted the instant power changes
~5 W per m² - less power than a light bulb, only while clear
Factory-cut to size - busbar finished and tested, ready to wire

Our old logo

A new look - the same factory

If you found us through social media, a marketplace listing or an older catalogue, you may recognize this colorful geometric mark: it is our previous logo. It still means us - Smart Glass VIP, the same factory, the same team and the same film.

Our social media accounts and pages across the web continue to carry this logo while the new one rolls out. Whichever mark you see, you are dealing with the manufacturer directly.
