The LigaSmart IK 55 is a 55-inch interactive information kiosk designed and manufactured by LIGA LLC, a Yekaterinburg-based Russian company specializing in interactive multimedia equipment. The display delivers 4K Ultra HD resolution up to 3840×2160, with brightness from 350 cd/m² and contrast from 4000:1.
An infrared multi-touch sensor registers up to 20 simultaneous contact points at a response latency under 10 milliseconds, making the unit fully responsive in high-traffic public spaces.
The enclosure is fabricated from steel and finished in any shade from the RAL catalog. Anti-vandal construction includes a tempered protective glass panel at least 4 mm thick, a lock-secured revision access hatch, and an electronic start key that restricts unauthorized power-up.
Two integrated stereo speakers enable multimedia audio playback without requiring an external sound system. An optional atmospheric LED edge lighting kit adds a distinctive visual presence suited to lobbies and exhibition halls.
The kiosk is engineered for both indoor and outdoor deployment. The outdoor configuration is sealed to IP65 and sustains operation from −40 °C to +70 °C through a moisture-resistant anti-corrosion body treatment.
Compute resources scale from 4 GB RAM with 128 GB SSD up to 32 GB RAM and 1 TB SSD, with OS support for Windows, Android, and Linux. Optional peripherals — Wi-Fi adapter, 4G modem, biometric scanner, QR and barcode reader, card reader, and contactless payment terminal — let a single chassis address a wide range of self-service scenarios.
The LigaSmart IK 55 is listed in the Russian Ministry of Industry and Trade register of domestic electronics under Government Decree No. 616, qualifying it for public-sector procurement under Federal Laws 44-FZ and 223-FZ.
