Empowering display industry professionals with cutting-edge insights and analysis
Earlier this month, Veeco, a maker of process equipment, said that it is planning to significantly reduce its future investments in Atomic Layer Deposition (“ALD”) technology. “While we have continued to make progress with our ALD technology development for advanced semiconductor applications, the expected timing for revenue realization has been delayed,” said John R. Peeler, … Read more

A total of 1,140 displays (not all digital) is expected.
Twenty years after being opened by Chancellor Helmut Kohl, the Heinz Nixdorf MuseumForum in Paderborn, Germany, has celebrated its anniversary. It has developed an idea of an ‘Internet Wall’ that is 13 metres long and is designed to react to visitors coming near the display. One of the images shown is of the first webcam … Read more
Amazon now has 100 titles of UltraHD Blu-ray discs available not only in the US, but globally, as the format does not have the same regional blocking features as DVD. There are 24 titles from the first four studios, Sony Pictures, Lionsgate, Warner Brothers and 20th Century Fox. At the moment, there are only a … Read more
Content is mastered in a dim environment and reproduced on a display whose performance is measured in a dark environment. But a lot of content is watched in environments that are not dark or dim. As a result, images may not look like what the content creator intended. A paper presented by Praveen Cyriac of … Read more
Keith Slavin of ISO Video presented a method for automated tone mapping of unsaturated HDR content down to an SDR range and BT.709 color gamut for distribution as an SDR signal. By using the inverse tone map at the end user display, one can then restore the HDR image without sending metadata. He calls his … Read more
Shane Mario Ruggieri, a Production Engineer, Producer and Colorist at Dolby Laboratories presented a paper titled, “Breaking out of the 100-nit Box – A Colorist’s View of HDR Grading.” In the talk, he explained that the 100 cd/m² box is a physical constraint, a standards constraint and a mindset constraint. To break out of this … Read more
In a paper presented by Peter Postma and a team from FilmLight, Postma started by noting that colorists first spend a lot of time color matching content from different cameras before creating the HDR and SDR grades. This is very time consuming, so he suggested colorists should use ACES-defined input device transforms (IDTs) for the … Read more
Several papers at the SMPTE conference were aimed at colorists working on the grading of HDR and WCG content. This is still a new area and most colorists have not yet tried to grade HDR/WCG content so there is a need for those more experienced to provide some hints, tips and updates to tools available … Read more
The opposite problem to gamut compression is gamut extension, which was discussed by Syed Waqas Zamir of the Universitat Pompeu Fabra in Spain. Here, the idea is to take the source content gamut delivered in BT.709 or DCI-P3 and expand it to the wider gamut capabilities of the display. Displays that can exceed the P3 … Read more
One of the important topics covered at the SMPTE conference was conversion from one color gamut to another. This is particularly important when content is encoded using XYZ or BT.2020 coefficients. Such content may be played back on displays with a variety of color gamut support so compressing the original content gamut to the particular … Read more
Spud (spontaneous pop-up display) is a new DLP-based collapsible rear-projection monitor designed for portability and being launched as a Kickstarter project. The 24″ final display has 1280 x 720 resolution and brightness is from 350 to 785 cd/m² with battery life from three hours to six hours, depending on the brightness. The unit can be … Read more
