The core of the HDR47E brightness performances is an array of 2202 independently controlled high power white LEDs as back lighting system.
Each LED emission level is controlled, consistently with the image on the LCD panel and with the specific light spreading function of the optical layers, in order to give the most appropriate brightness contribution to the final image.
Computer generated images have always been a sure bet for HDR. This was an absolute truth at the time of HDR47E introduction to the market, when HDR camera were nothing more than prototypes, while simulation systems could easily output high dynamic range images.
The creation and distribution of HDR contents is a big challenge, facing the real-world multitude of devices and installations requires reliable and flexible tools for evaluation and decision making.
Beinng our HDR47E an absolutely calibrated monitors, it is perfect as a reference device for testing HDR brightness levels and simulating the most different use user fruition condition.
The input format are totally agnostic, allowing an easy interface with any source and a direct comparison of different commercial solutions.
Let’s consider the following facts:
VIDEO HDR data handling requires very high computational and storage performances, way above the capabilities of standard consumer and prosumer hardware.
Contents distribution market trend is definitely headed towards streaming technologies that offer limited resources, in particular a limited and highly variable bandwidth
When dealing with contrast figures of HDR47E series monitors, their specific hardware peculiarities must be taken into account.
Full ON full OFF contrast is virtually infinite: when a totally dark image is visualized, the monitor can turn the relevant LEDs off, resulting in a zero value light level.
When talking about calibration for the HDR47E monitors, we are talking about something totally different form traditional methods.
Traditional calibration consists in measuring the output of a given input and applying some correction , usually through lookup tables, in order to have them matching. Everything in between is just ignored.
Calibration on the HDR47E can be called Absolute Calibration and only involves the monitor, independently from the source.
