GreenTouch pitches custom touch foils for through-glass installations

GreenTouch is promoting custom projected capacitive touch foils for storefronts, kiosks, facades and medical spaces that need vandal resistance, weatherproofing and clean integration. The company says its foils work through glass up to 20 mm thick and support custom sizing, adhesive options and driverless operation across major operating systems.

Why it matters: - Through-glass touch can turn standard glass, windows and acrylic partitions into interactive surfaces without exposing the sensor layer to vandalism, weather or harsh cleaners. - The format is aimed at storefronts, outdoor architectural facades, self-service kiosks and sterile medical environments where durability and hygiene matter. - GreenTouch is positioning custom touch foil design as a fit-for-purpose alternative to surface-mounted touch screens.

What happened: - GreenTouch described itself as a custom touch foil solution provider and outlined its projected capacitive touch foil lineup for through-glass integration. - The company said its custom foils support glass thicknesses up to 20 mm and are built for optical transparency, tailored dimensions and multi-platform driverless compatibility. - GreenTouch invited integrators and display manufacturers to submit architectural specifications and glass dimensions for custom engineering and sample fulfillment.

The details: - The touch foil uses two flexible optical-grade PET sheets with a microscopic grid of conductive copper microwires. - A flexible printed circuit, or FPC, tail connects the grid to an external controller board. - An AC excitation voltage creates a projected capacitive electromagnetic field that passes through the glass overlay. - The foil and controller stay behind the glass on the interior side, leaving the outer surface smooth and unbroken. - GreenTouch says that setup protects the sensor from scratches, graffiti, rain, snow and chemical cleaning solvents. - For permanent installs, GreenTouch offers factory-laminated optical clear adhesive, or OCA, for wet lamination to glass. - The company says OCA improves optical matching, reduces internal reflections, removes air gaps and helps prevent bubbling or delamination. - For temporary retail and leased spaces, GreenTouch offers electrostatic cling and semi-permanent adhesive options that can be removed and repositioned without sticky residue. - GreenTouch also says its PET substrates and UV-blocking adhesive formulations are designed to resist yellowing and optical degradation in direct sunlight. - The company says controller electronics use high-voltage excitation drivers to support touch detection through single-pane glass, laminated safety glass and double-glazed insulated units up to 20 mm thick. - Controller firmware includes dynamic auto-calibration to track changes in capacitance from temperature, humidity and moisture on the outer glass. - GreenTouch says the system is designed to reduce false touches from rain or condensation while keeping response times under 10 milliseconds. - Standard sizes range from 15 inches to 120 inches diagonal, with custom engineering available for larger builds. - Supported aspect ratios include 16:9 and 16:10, plus ultra-wide formats such as 21:9 and 32:9. - FPC tail exits can be placed along any edge or corner to fit tight enclosures. - Grounded copper shielding layers in the FPC tail are designed to reduce electromagnetic interference from nearby LCD backlights or power supplies. - GreenTouch says its microwires are under 10 microns wide, making the conductive grid virtually invisible. - Optical transparency is said to exceed 90% to 92%, preserving color and brightness on rear-projected images and high-brightness LCD monitors. - Controllers use digital frequency-hopping algorithms and active noise filtering to isolate touch signals from PWM LED backlight noise. - The company provides step-by-step video installation guides and application toolkits for wet lamination. - GreenTouch also offers evaluation prototypes so teams can test through-glass sensitivity on the actual installation glass before rollout. - The controllers support USB HID for driverless plug-and-play use on Windows, Android, Linux and macOS. - The flexible polyester substrate can conform to gentle single-axis cylindrical glass curves. - GreenTouch said its manufacturing and custom design services are backed by CE, FCC and RoHS certifications. - The company directed prospective customers to its website for custom engineering evaluations. - GreenTouch also listed social profiles on LinkedIn, Facebook and YouTube.

Between the lines: - The pitch centers on replacing exposed touch hardware with a protected behind-glass architecture, which is the main tradeoff between durability and installation complexity. - The adhesive choices suggest GreenTouch is targeting both permanent architectural deployments and short-term retail campaigns. - The emphasis on UV resistance, water rejection and EMI shielding points to outdoor and high-noise commercial settings as the strongest use cases.

What's next: - GreenTouch says it will work from customer specifications and glass dimensions to produce custom engineering evaluations. - The company is also offering sample validation and rapid fulfillment for integrators that want to test fit and sensitivity before deployment. - Prospective buyers will likely use those samples to confirm glass thickness, moisture behavior and enclosure routing before committing to full-scale installations.

The bottom line: - GreenTouch is selling through-glass touch foils as a customizable, protected interface layer for commercial and industrial glass surfaces.
