"Color IQ™" is an advanced light-emitting semiconductor technology developed by QD Vision, Inc. By integrating QD Vision's "Color IQ™" optical component with Sony's unique display technologies, this television set achieves a significantly wider color gamut, which provides a far more natural and vivid viewing experience. The "Color IQ™" optical component produced by QD Vision contains a very small quantity of cadmium. This cadmium is fixed within a hardened resin which is sealed in glass inside the television. Customers can therefore enjoy using this television without being exposed to cadmium.
This television complies with all applicable environmental laws and regulations in countries and regions where Sony sells it. Sony's aim is to protect the environment throughout the life cycle of its products. As part of this effort, Sony provides its consumers, authorized repair workshops and recycling companies with information relating to the "Color IQ™" component in order to enable proper collection, handling, recycling and disposal of the component upon repair or disposal of the television, in accordance with applicable local environmental laws and regulations.
Q1. What kind of technology is "Color IQ™"?
"Color IQ™" is an advanced light emitting semiconductor incorporating quantum dot technology, developed by QD Vision, Inc. An optical component using Color IQ™ technology that was manufactured by QD Vision is used in this TV. This component contains very small semiconductor particles which are fixed within hardened resin and then sealed in glass. When lights of specific wavelengths hit this tube, they are changed into high purity blues, greens and reds that are mixed to produce white light. This TV is therefore able to achieve a color gamut width that far exceeds conventional LCD television sets using edge-lit single color LED backlight systems.
The wavelength of light emitted by quantum dot technology is reliant upon chemical elements. In order to be able to achieve such a wide color gamut, a very small amount of cadmium*1 must be included as semiconductor particles, fixed within the hardened resin that is sealed in glass. Sony is exploring cadmium-free technology as an alternative solution. However, from the perspective of color, light emission efficiency, reliability and suitability for mass production, there are currently no practical alternatives at the level required for commercialization.
Yes, it is compliant. Cadmium is one of six substances,*1 the use of which is restricted in electrical and electronic equipment by the EU RoHS Directive. However, the EU RoHS Directive includes a range of exemptions*2 that permit the use of these substances subject to quantitative limits for specific applications, based on the current lack of reliable alternatives amongst other considerations. The application of cadmium in QD Vision's Color IQ™ optical component is exempted under the EU RoHS Directive. Furthermore, Sony's televisions which incorporate the Color IQ™ optical component comply with all applicable environmental laws and regulations in the countries and regions where Sony sells them.
No. The Color IQ™ optical component is located inside the backlight unit of the TV's LCD panel, the cadmium is fixed within hardened resin and then sealed in glass. This means that customers are able to enjoy using this TV without being exposed to cadmium.
Sony provides its consumers, authorized repair workshops and recycling companies, with information relating to the "Color IQ™" component to enable proper collection, handling, recycling and disposal of the component upon repair or disposal of the television, in accordance with local environmental laws and regulations. The quantity of cadmium is very small and so if this item is disposed of in accordance with applicable local environmental laws and regulations, it will not present any risk to health and the environment. The glass component has been tested for potential elution by an independent third-party testing facility according to the US Environmental Protection Agency's (EPA) TCLP standards, and found no leaching of cadmium from the component even when damaged.
Sony wants to play our part in creating a sustainable society and wants to achieve a zero environmental footprint throughout the lifecycle of our products and business activities, as outlined in our medium to long-term environmental plan, "Road to Zero". We have set targets based on climate change, resource conservation, management of chemical substances and biodiversity conservation and are working towards achieving these goals throughout our business activities and our product lifecycles.
