Indoor double-sided stele (2 x 55 inches / 4K UHD / 500 nits / touch)

In heavily frequented buildings, information must not only be visible, but also available at the right time and in the right place—and ideally for both directions of traffic. The double-sided 2×55″ 4K Touch indoor stele is designed as a professional, interactive digital signage stele for precisely this requirement. Two opposing display surfaces create a central communication point that reaches visitor flows in both directions simultaneously. This is particularly relevant in passageways, large entrance areas, waiting zones, and hubs, where single-sided systems often only cover part of the walkways.

The stele uses two 55-inch LCD panels in portrait format (9:16). This format is practical for vertically structured content: directions, notices, event information, service information, or campaign motifs can be clearly structured and quickly understood. With 4K UHD (3840×2160), each display offers high-detail resolution. This is an important point in the B2B and public sector context, because content often consists of text, pictograms, site plans, or detailed visualizations that should look clean even when viewed up close.

The brightness of 500 nits is designed for indoor environments. This supports readability in areas with daylight, glass fronts, or bright general lighting—typical conditions in foyers, mall passages, or reception halls. Complemented by 16.7 million colors and a wide viewing angle (89/89/89/89, min., CR≥10). This is relevant because visitors often view content in open spaces from side angles.

The key difference to the non-touch version is the option to configure the kiosk with PCAP touch. This transforms a purely informational and advertising space into an interactive touch kiosk —suitable for applications where users are expected to select and explore content themselves. Typical areas of application include interactive orientation points, digital product advice, self-service scenarios, or information points in large buildings. This is particularly relevant for decision-makers in IT, facilities, purchasing, marketing, and project management when processes need to be standardized, information provided consistently, and visitors guided to their destination more quickly.

In addition to display and touch quality, stability, protection in public areas, and predictable operation are particularly important in everyday project work with double-sided systems. The stele is equipped with safety glass and has a robust metal housing and a stable base. This supports safe placement in high-traffic areas and reduces risks in daily operation—such as accidental bumping or heavy use in publicly accessible zones.

Durability is also a key factor, especially for rollouts in branch networks or long-term building concepts. The LED backlight has a minimum service life of 50,000 hours. This makes it easier to calculate operating and maintenance windows and replacement cycles.

Interfaces such as HDMI, LAN, LTE, USB, WiFi 6, and Bluetooth 5.4 are available for integration into different location conditions. This is practical because installation locations can vary—from structured cabling sites to areas where flexible network connectivity is required. In addition, the stele is available in black or white, which facilitates visual integration into high-quality architecture, guidance systems, and corporate design specifications.

As a double-sided digital signage stele with touch option, this model is particularly useful when a location needs to cover two viewing directions and enable interaction at the same time – with clear 4K display, robust construction, and hardware designed for continuous operation.

intended use

The double-sided Indoor Stele 2×55″ 4K Touch is designed for indoor areas where visitor flows come from two directions and information must be visible in both directions at the same time – supplemented by interaction when processes or information retrieval are to be actively controlled by users. As a double-sided touch information stele, it is particularly suitable for central points in the building: entrances, intersections of walkways, transitions between areas, waiting areas, or large reception areas. The benefit lies in the efficient use of space: a location becomes a point of communication and interaction on both sides.

In shopping centers and large retail spaces, the stele can be used in mall passageways, at escalators, in front of anchor tenants, or at transitions between floors. Typical content includes directions (e.g., "restaurants," "restrooms," "service point"), information about promotions or events, and orientation within the center. The double-sided design allows visitors to be reached in both directions. With the touch option, the stele can also serve as an interactive information point where visitors can search for specific shops, services, or routes.

In train stations, airports, and mobility environments, the combination of visibility and orientation is particularly important. A double-sided digital signage stele is suitable for providing information about areas, services, waiting zones, or visitor information. The touch function can help to make information accessible in a structured way – for example, by category or location. Especially in transition areas with changing lighting conditions, the indoor brightness of 500 nits ensures stable readability.

In hotel lobbies, conference centers, and event venues, the stele can serve as a central information point: daily programs, room information, event overviews, or service information can be displayed in such a way that arriving and departing guests alike can see them. With the touch option, the stele can also be used as an interactive guide or information point without requiring permanent staff.

In public institutions (e.g., administration, education, healthcare), the stele is useful when visitor guidance and information are to be provided at central points—such as in entrance areas, at junctions, or in large waiting areas. Interaction is particularly helpful here when visitors need to find the right point of contact quickly. In such environments, robust construction, safety glass, and stability are crucial because the devices are permanently exposed to public traffic.

special features

The key distinguishing feature of this solution is its double-sided design with 2×55 inches: two opposing display surfaces enable communication in both directions of travel – ideal for passageways, large entrances, and intersections. Each display operates in portrait mode (9:16) and offers 4K UHD (3840×2160), allowing both eye-catching motifs and detailed content (e.g., maps, notices, text information) to be displayed clearly. With 500 nits, the stele is designed for indoor environments where daylight and bright lighting affect readability.

With PCAP touch, the kiosk becomes an interactive touch information kiosk and supports applications in which users are supposed to select and explore content themselves—e.g., orientation, information retrieval, or self-service. Safety glass, a robust metal housing, and a stable base are key features for long-term use in public areas. They support stability and everyday usability in locations with high visitor traffic.

The LED backlight lifetime of 50,000 hours facilitates planning for long-term operation and reduces replacement costs during the course of the project. In addition , 16.7 million colors and a wide viewing angle (89/89/89/89, min., CR≥10) ensure that content remains clearly visible even from side viewing angles. Interfaces such as HDMI, LAN, LTE, USB, WiFi 6, and Bluetooth 5.4 are available for integration into different location conditions. In addition, the stele is available in black or white, which supports its visual integration into architectural and corporate design concepts.
