Customer & Application

Primare AB is a high-end Hi-Fi manufacturer that focuses on great sound, Scandinavian design and aesthetics. PSC supplies filters (display windows) for a wide range of Primare’s products, here among SP33 AV Preamplifier

Most important requirements

The Primare designers required a front design uniting aesthetics and function, creating a unique, highly differentiated product. A white (RGB) OLED delivers the white colour output, however the colour needs to be tuned into the exact “Primare white” colour. Furthermore, a black panel effect is desired.


To achieve the required visual appearance, the solution chosen was a grey shaded Solaris filter. The filter produces the exact desired colour output and maximises the readability. Furthermore, a black panel design is achieved when the display is turned off. The filter is CNC-milled, screen printed and applied with a die-cut double sided adhesive tape. 

Customer benefits

A ready-to-mount display window which underpins the unique product design. The display window solution supports the design and quality, which Primare wishes to communicate to its customers.
