At the end of 2019, TDC Polska carried out an installation for the public Swedish TV station SVT. The project included the delivery of 6 SCEO®VIDEOWALL screens with 1.8 mm diode spacing, installation and configuration according to studio guidelines.
TDC Polska delivered 5 stationary screens and one with a mobile structure with a total area of 65 m2. The large curvature of the screens and the required viewing angles were a challenge, which we met by selecting the appropriate RGB diode at the studio testing stage. In this project, we used flexible modules that enable us to achieve ideal curves for small radii of curvature without visible offsets, which are typical for standard cabinets. Thanks to this solution, we have obtained both concave and convex screens. In order to ensure full uniformity with other elements and lighting of the studio, the screens have been calibrated and configured to obtain excellent quality of the broadcast image. Structures for both stationary and mobile screens were important elements of this project. For stationary screens, we have designed a steel structure especially for the implementation purposes, the elements of which were laser cut with high precision to obtain perfect curves. The entire structure has been integrated into the design of the TV studio so that it co-creates the scenery with decorative elements and lighting. For the mobile screen we created a dedicated structure on Blickle wheels with a retractable handle, which allows the screen to be transported between studio rooms without fear of mechanical damage. The structure is also prepared to overcome small obstacles, bends or thresholds in the TV studio building. In addition to facilitating transport, the mobile structure also allows the screen to be used as part of the scenery, which can be remotely controlled and changed at any time. In addition, we provided 12 NovSTAR mCTRL 660 pro controllers supporting interlaced TV signal and IC drivers ensuring refresh rates up to 3840 Hz to minimise the problem of screen flickering in the camera.
