Legacy calibration methods rely on arbitrary colour targets being chosen for the LEDs, with the technicians in the factory trying to find a balance between performance and uniformity by trial and error. It’s often a lengthy and imperfect science, with the only means of getting uniformity to calibrate all LEDs to match the performance of the one which is performing worst. These decisions are then fixed for the lifetime of the panel, and actual users rarely have clear information about a panel’s capabilities short of plugging it in and making their own visual assessment.
When you calibrate your panel with the Hydra measurement system, you get a DynaCal report that gives you clear, useful, interactive data, including the performance of every individual pixel measured scientifically and objectively. It’s likely that most of the time, all the data you need from your report is there at the top left – headline figures detailing maximum luminance and for each primary colour the percentage of the Rec2020 colour space (typically used for HDR) that the LEDs can achieve.
But we think data is beautiful, and Hydra gives us lots of it! So if you really want to get the most out of your DynaCal report you can discover more about your panel through a series of clear, easy to read, interactive graphs.
The colourspace chart lets you check how wide colour gamut content will be reproduced by the panel. Zoom in to see the spread of performance pixel-to-pixel, and compare the performance to colour spaces such as Rec.2020, Rec. 709 and DCI-P3.
The DynaCal report also gives you precise brightness information, with an accurate physical representation of every single pixel on the panel, in all three primary colours.
DynaCal reports are helpful for manufacturers:
- Provides evidence of good panel performance and achievable colour targets
- Understand panel capabilities scientifically without a processor present
- Supports fault finding
- Measure sample panels and check for consistency at a glance
- Catch dead, dying or low performing LEDs before they leave the factory
And they are also helpful for end users:
- Content creators get true insight into the colours the LEDs can reasonably achieve
- Accurate data to work with when planning your production, particularly useful for demanding content e.g. extremely bright, extremely vivid, or with a wide dynamic range
- Make confident colour choices for your content, since you know exactly what will be in gamut and out of gamut
- Know the max brightness and colour capabilities before you buy your LED panels
Whether you’re deep-diving into panel performance or just want to be confident of the headline capabilities, we hope DynaCal reporting is proving useful for you. To learn more, check out our DynaCal reporting app page.
