Retailers and property owners who want digital content on glass surfaces without sacrificing natural light face a specific engineering challenge: how to mount a display that is thin, light, and visually permeable enough to preserve the transparency of a shop window while still delivering sharp, dynamic visuals. Adhesive-mounted transparent LED screens address this need directly, and the technology developed by Shenzhen Showho, operating internationally under the Whaley-LED brand, offers a detailed illustration of how this category of product is engineered and deployed.
What Is an Adhesive-Mounted Transparent LED Screen
An adhesive-mounted transparent LED screen is a film-type display that attaches directly onto glass surfaces using adhesive mounting, rather than requiring a bulky frame or support structure. Shenzhen Showho's industry pain point insight is straightforward: conventional LED displays are often heavy, thick, and block light, which makes them poorly suited to glass curtain walls and creative installation scenarios that require the display to remain transparent, light, and adaptable to curves. The company's Holographic Transparent LED Display line, marketed internationally under Whaley-LED, was developed specifically to solve this problem through a frameless design, a PCB with hollow mesh circuits, and a lamp board thin enough to sit flush against glass.
The Technology Behind the Transparency
The permeability and thinness of these screens are not incidental features; they result from a self-managed technology chain that spans IC bare chip architecture and functional design, LED bracket, LED packaging, and electronic circuit design. Shenzhen Showho holds dozens of invention and utility model patents related to film screens, and it has developed its own IC with strong driving performance, paired with a lamp-driver integrated LED design. This combination allows the lamp board to use a hollow mesh circuit structure that keeps the physical footprint of each LED minimal while still supporting high refresh rates and stable color output.
Across the entire Holographic Transparent LED Display series, sensory permeability exceeds 80%, and individual models range from more than 70% to more than 99% visual permeability depending on pixel pitch. The screen body itself measures below 2 mm in thickness, and screen weight stays under 3 kg/m2 for the series, which reduces the structural load placed on glass curtain walls, shop windows, and other architectural surfaces.
Key Technical Specifications
For buyers evaluating a transparent LED screen for shop window use, several measurable specifications determine real-world performance:
- Pixel pitch: options range from 2.5 mm to 50 mm across models, allowing selection based on expected viewing distance.
- Brightness: ranges from 800 cd/m2 to 5000 cd/m2 across models, with automatic and manual adjustment based on ambient brightness.
- Refresh rate: greater than 3840 Hz, paired with a frame change rate greater than 60 Hz.
- Gray level: at least 16 bit, supporting smooth color transitions.
- IP rating: better than IP45.
- Average lifespan: more than 100,000 operating hours, with an MTBF greater than 10,000 hours.
- Dead pixel rate: less than 1 in 10,000, discrete distribution.
- Attenuation rate: less than 0.05% within 2 years.
- Control system compatibility: Colorlight and NovaStar, supporting both synchronous and asynchronous control.
Specific models such as the PH2.5 version offer visual permeability above 70% with a viewing distance of 3 m to 150 m, while the PH50 version reaches visual permeability above 99% for applications viewed from 50 m to 350 m. This range means a shop window installation and a large-scale building façade can both be addressed within the same product family, simply by selecting the appropriate pixel pitch.
Installation Flexibility for Shop Windows
A defining characteristic of this screen line is flexible installation. Beyond direct adhesive mounting onto glass, the screens also support hanging display and fixed installation, and they can be cut and bent to match irregular shapes. Curved installation is possible with a radius greater than 600 mm, which accommodates corner screens, cylindrical surfaces, and S-shaped inner and outer arcs. For shop window applications in particular, this means a single continuous display surface can wrap around a window frame or follow a curved glass panel without visible seams.
Regarding splicing, one description notes a maximum splice height of up to 8 m, while a later English-language note specifies up to 4 m without a mid-span power supply, with one-side length not limited. This level of detail matters for retailers planning multi-panel installations across large display windows, since it clarifies where power infrastructure needs to be positioned.
Product Variations for Retail Environments
Within the broader LED Holographic Screen category, Whaley-LED offers variations tailored to different retail and commercial needs. The LED Holographic Screen Advertising Machine Series packages the transparent display into a self-contained advertising machine format suited to retail and commercial advertising environments. The LED Holographic Screen Double-Sided Display Series addresses locations with audiences on both sides of a window, offering independent content on each face; one side can show dynamic new product promotion while the other communicates a brand story, with a weight of about 4.5 kg/m2 and thickness of about 2 mm, and visual permeability over 90%. Additional product lines, including the LED Grille Screen, LED Transparent Screen, LED Photoelectric Glass, LED Crystal Film Screen, and LED Mesh Screen, extend transparent display options for commercial display and engineering projects more broadly.
Industry Applications
The adhesive-mounted transparent LED screen line is positioned for use across commercial display windows, commercial curtain walls, exhibition halls, creative displays, entertainment and cultural tourism venues, automobile 4S stores, airport concourses, building curtain walls, and commercial centers. This spread of use cases reflects the underlying design priority: a display that does not interrupt daylight or sightlines, whether the installation is a single shop window or a larger architectural glass surface.
Company Background and Delivery Model
Shenzhen Showho was founded in 2015 and is headquartered in Shenzhen, China. The company's early focus was the domestic high-end rental display market, including XR virtual shooting screens and carbon fiber rental screens. In 2025, it established an overseas business unit and launched the Whaley-LED brand to provide OEM and ODM services for overseas commercial display and engineering projects. This structure, combining self-managed R&D, structural design, and in-house production, allows the company to respond to custom sizing, cutting, bending, and curved installation requirements directly, rather than relying on external manufacturing partners.
For organizations evaluating transparent LED technology for shop windows, the relevant decision points are the required pixel pitch for the intended viewing distance, the installation method (adhesive, hanging, or fixed), and whether curved or multi-panel splicing is needed. Shenzhen Showho's documented specifications, under the Whaley-LED brand, provide the technical basis for making that evaluation.
