{"title":"Display Industry Ready for New EU Cadmium Regulations","authors":"Glen Dickson","doi":"10.1002/msid.1504","DOIUrl":"https://doi.org/10.1002/msid.1504","url":null,"abstract":"<p><b>IN LATE MAY, THE EUROPEAN UNION (EU) TIGHTENED ITS</b> restrictions on the use of the toxic metal cadmium in electronic devices, updating a rule that had been in place since 2017. But the new EU regulations should not have a big impact on the display business, say industry insiders, as most manufacturers are already building products on a global basis that comply with the new limits.</p><p>Cadmium first made its way into displays over a decade ago in the production of quantum dots (QDs), semiconductor crystals that generate different colors when subjected to light or electricity depending on their size. QDs, which also can be made from other materials such as indium phosphide, are widely used to perform color conversion in LCD displays by “downshifting” white or blue light from an LED backlight to red or green. The result is vivid color reproduction, including high dynamic range (HDR) with wide color gamut.</p><p>Cadmium also is one of the elements and compounds regulated by the European Commission (EC, the EU's executive arm) through its Restriction of Hazardous Substances (RoHS) rules, which began in 2006 to limit the use of hazardous chemicals in consumer electronics. The RoHS rules (specifically Directive 2011/65/EU) govern the use of substances such as lead and mercury and generally set limits on a parts-per-million (ppm) basis. The limit for lead and mercury in a “homogenous part” is 1,000 ppm, for example, while cadmium is set at 100 ppm.</p><p>Exemptions to the RoHS rules are possible if a strong argument can be made for using a restricted material over a substitute, such as significant performance, efficiency, or related environmental benefit (e.g., less electricity consumption). Such exemption requests usually are evaluated by an outside party, which then makes a recommendation to the EC.</p><p>Cadmium has been used in lighting and displays under such an exemption (Exemption 39), which was granted by the EC in 2011 after a lengthy evaluation and recommendation by the Oeko Institute in Germany. At the time, QDs based on cadmium selenide were far more efficient and reliable than any alternative and were being developed for use in encapsulating films by companies such as 3M. The EC granted an exemption allowing “10 micrograms of cadmium per square millimeter of light-emitting area,” or 10 grams per square meter, which is roughly the size of a 65-inch TV.</p><p>While the units were different, this worked out to be much more cadmium than the standard 100 ppm limit under RoHS, said Peter Palomaki, owner and chief scientist at Palomaki Consulting. In 2017, the exemption was subsequently modified with Exemption 39(a) to allow only 0.2 micrograms per square millimeter (or 0.2 grams per square meter) of light-emitting area. Palomaki concedes that the differing units of measurement in the EU rules can be confusing.</p><p>“The 0.2 grams per unit area, per square meter, is basically saying how much you can use over the whole screen area, which","PeriodicalId":52450,"journal":{"name":"Information Display","volume":"40 4","pages":"37-39"},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/msid.1504","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141631210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of RIT's core differentiators is the school's extensive cooperative education or “co-op” program, where students gain real-world hands-on experience working in full-time (typically paid) positions in their fields of study.</p><p>The Munsell Color Science Laboratory at RIT focuses on the science behind the human perception of color and imaging, and how it is researched, experimented upon, and explored. Mark Fairchild is a tenured professor in the Color Science program at the Munsell Laboratory, training the next generation of color and imaging scientists. He is also the recipient of the 2021 SID Otto Schade Prize for his contributions to quantifying spatial display performance and analogous human visual performance metrics.</p><p>Fairchild has been involved with research in the visual sciences for 40 years. He initially was attracted to RIT as an undergraduate student interested in photography. When visiting the campus, he learned of RIT's program in Photographic Science (now called Imaging Science) and immediately was smitten with the ability to combine his interests in photography with talents in math and science for a potential career in industrial research.</p><p>RIT's focus on color and imaging and its Color Science program are unique. Historically, the Munsell Laboratory is recognized for research in the practical psychophysics of color perception and relating those perceptions to developing technologies, such as imaging systems and systems of color measurement and specification. Currently, researchers in the lab are studying topics such as fundamental attributes of color perception, the conservation and spectral imaging of cultural heritage, color in augmented and virtual reality (AR/VR) systems (<b>Fig</b>. 1), perception and processing in high dynamic range (HDR) imaging systems and displays, and the interaction of humans with advancing technologies such as social robots.</p><p>One current study is focusing on how skin tone, lighting, and facial realism impact the overall positive experience that a person has with an AI-based animated support bot.
