Letterbox Displays

Optimised for Constrained Form Factors
The primary advantage of letterbox displays is their ability to provide meaningful graphical interfaces within height-restricted enclosures.
Their wide aspect ratio supports cleaner front-panel layouts while avoiding oversized or awkward display apertures. This allows displays to integrate more naturally within compact products without dominating the enclosure design.
GTK works with customers to select display formats around enclosure geometry, mounting constraints and interface requirements from the earliest stages of development.
Clear Information & User Interface Design
Letterbox displays are well suited to horizontally structured interfaces, including status information, alerts, segmented data and navigation elements.
GTK considers viewing angle, brightness performance and interface layout to ensure information remains clear and readable in real-world operating conditions, including environments where users may approach equipment from different positions.
This approach supports interfaces that are both practical to use and visually consistent with the wider product design.


Engineered Integration & Custom Solutions
GTK provides complete integration support for letterbox displays, including capacitive touch functionality, bespoke cover lenses and tailored electrical and mechanical interfaces.
Each solution is engineered around the application requirements, helping simplify assembly, maintain manufacturability and support reliable long-term deployment across production volumes.
