- Product Description
-
What is this product? Wireless Light-Up Letter Glass is an innovative illuminated signage product combining transparent conductive film, micro LEDs, and magnetic resonance wireless power technology. It completely eliminates traditional power cords. Simply place the glass near the base to achieve contactless power transmission and illuminate the text, presenting a true "floating illumination, zero-cable" minimalist effect.
What are the core specifications? Light transmittance ≥85%, wireless power distance 1-3cm, glass thickness 2-5mm, operating voltage 12V/24V safe low voltage, power transmission efficiency >85%, LED lifespan over 50,000 hours.
What scenarios is it suitable for? Luxury storefront windows, high-end jewelry display cases, smart home glass partitions, high-end bathroom mirrors, technology exhibition hall wayfinding, and other scenarios requiring ultimate cleanliness and a technological feel.
What advantages does it have over traditional illuminated letters? No exposed cables, minimalist and beautiful, can be moved at any time; no plug-in interface, better waterproof and moisture-proof; extremely simple installation, just place it to power on; glass material does not yellow, high-end texture.
Who manufactures it? Dongguan Mingda Glass Co., Ltd., founded in 2007, with 19 years of specialty glass experience, holding 31+ patents (including conductive glass and anti-fog glass technologies), and participating in drafting the industry standard T/UNP 249—2024 "Electric Heating Coated Glass".📌 Product Overview
Wireless Light-Up Letter Glass is Mingda Glass's latest masterpiece in the field of transparent conductive glass. By etching invisible transparent conductive film circuits on the surface of ultra-clear glass, precisely attaching micro LEDs, and integrating advanced magnetic resonance wireless power technology, this product achieves "zero-cable" illuminated signage.
No matter how traditional illuminated letters are hidden, a power cord is always needed. Wireless Light-Up Letter Glass completely breaks this limitation, making the entire glass panel a pure technological artwork. It is widely suitable for luxury storefront windows, jewelry display cases, smart homes, and high-end commercial spaces. Mingda Glass has 19 years of specialty glass R&D and manufacturing experience and holds 31+ patents, providing one-stop high-end customization services from design to production for global customers.1. Wireless Power Technology: Saying Goodbye to the Last Cable
In high-end display spaces, cables are often the biggest culprit destroying minimalist aesthetics. Wireless Light-Up Letter Glass uses magnetic resonance wireless power technology. The transmitter coil is hidden in the base or display rack, and the receiver coil is integrated into the glass along with the invisible circuit. When the glass is placed on the base, the two transmit electrical energy contactlessly through a magnetic field, illuminating the text or patterns on the glass.
This design brings a revolutionary installation experience: no drilling, no wiring, lights up upon placement. At the same time, the design without exposed electrodes gives the glass better waterproof and moisture-proof performance, making it safe to use even in bathroom environments.
2. Core Technologies
2.1 ITO Invisible Circuit and LED Attachment
A nanoscale ITO transparent conductive film is deposited on the surface of ultra-clear tempered glass, and precise invisible circuits are created through laser etching. Micro SMD LED beads are attached to circuit nodes. After power-on, light is uniformly emitted from inside the glass, with no circuits or LED beads visible on the front or sides.
2.2 Magnetic Resonance Wireless Power Module
A micro wireless receiver coil is integrated into the bottom edge of the glass, and a wireless transmitter module is built into the base. Through the principle of magnetic field resonance, electrical energy is efficiently transmitted into the glass, with power transmission efficiency of over 85%, meeting high-brightness illumination requirements.
2.3 Ultra-Clear Tempered Substrate
Uses ultra-clear tempered glass with a light transmittance of ≥91%. The base color is pure without green tint, ensuring clear and bright text display, while also possessing extremely high impact resistance and weather resistance.

Frequently Asked Questions (FAQ)
❓ How is the Wireless Light-Up Letter Glass powered?We use magnetic resonance wireless power technology. A micro receiver coil is built into the bottom edge of the glass, and a transmitter module is built into the matching base. When the glass is placed on the base, the two transmit electrical energy through magnetic field resonance, illuminating the LEDs inside the glass. The entire process requires no physical plugs or wire connections, achieving true "contactless power supply."❓ Are there high requirements for the placement position of the glass?Not high. Our base is designed with a guide groove or positioning area. As long as the receiver module at the bottom of the glass is roughly aligned with the transmitter module of the base (within a distance of 1-3cm), stable power supply is achieved. The glass does not need to be locked tightly to the base; you can easily pick it up or move it.❓ Is this glass suitable for outdoor use?The standard model is mainly designed for indoor high-end display. If used outdoors, the glass itself has excellent weather resistance, but it needs to be paired with a waterproof base housing or installed in a sheltered display window to prevent water from entering the base circuit board.❓ Can irregular patterns or logos be customized?Yes. We support customization of any flat text, logo, or complex lines. Just provide vector drawings (such as AI, CDR, PDF formats), and our technical team will design the invisible circuit routing based on the pattern to ensure uniform illumination without breakpoints.
