LED panel design is all about trade-offs between different aspects of visual performance.
Pushing for a faster refresh rate may mean reducing PWM bit depth. Increasing maximum brightness may compromise low brightness performance. Panel manufacturers seek to achieve a good balance, and that one-size-fits-all configuration is set for the life of the panel.
But what if your particular application means you care more about one aspect of performance than others? Why shouldn’t you be able to choose a configuration that meets your particular requirements? Well, now you can with Operating Modes, available from Tessera version 3.3 onwards.
All panels will have a default operating mode that aims for a balance across all aspects of performance – suitable for general-purpose use. But where appropriate, we can now support alternative modes for a panel type that prioritise a particular aspect of performance, and users can switch between operating modes instantly from the processor’s user interface.
For example, some panel types are limited in the high frame rates they can support – and this is because running at higher frame rates would compromise some other aspect of performance that would not be appropriate general-purpose use. But now we can create an alternative operating mode that supports the maximum possible frame rate, so that those needing that capability can choose it without compromising panel performance in other situations.
Studio Mode is a long-standing Tessera feature allowing users to sacrifice maximum brightness in order to increase bit depth for better performance at low brightness. Studio Mode is now just one of numerous possible Operating Modes that allow tailored performance for particular situations. Each Operating Mode can also store its own PureTone correction, to ensure colour accuracy whichever mode you are using.
Not every panel type will instantly have lots of operating modes. We will work with panel manufacturers to create new modes where we see a clear opportunity to increase one aspect of performance beyond what is possible in the default mode. Users can contact our support team to enquire about adding other operating modes if they have a specific requirement.
