- Gate 02 (Parts Development Stage): An environmental evaluation of each part under
development is conducted (consisting of three stages: (1) document review; (2) XRF test and (3) precision analysis)
- Gate
03 (Product Development Stage): An environmental evaluation of the product model and product labeling are conducted (including RoHS verification)
- Gate 04 (Mass Production Stage): Process management through the periodic testing of mass-produced parts for any hazardous substances
(including rate-based tests based on risk assessment)
We operate a Hazardous Substance Management System for Products that
effectively manages hazardous substances by classifying them into four levels: A-I, A-II, B-I, and
B-II. In particular, in addition to substances prohibited by global hazardous substance regulations on products, we have designated substances causing harm to the human body and the environment as Level B
substances. By developing alternative technologies and parts and applying them to our products, we continually strive to achieve a gradual reduction and elimination of non-prohibited hazardous substances.
- Level A-I (Prohibited Substances): Prohibited substances designated under the RoHS regulations
(i.e., 10 regulated substances) and those designated by specific customers
- Level A-II
(Prohibited Substances): Substances prohibited by regulations and conventions other than those covered under Level A-1 and those designated as such by customers
- Level B-I (Substances Subject to Voluntary Reduction): Substances that are being voluntarily
replaced over a certain period of time
- Level B-II (Substances Under Observation): Substances
that are not currently banned, but are expected to become prohibited in the future
Moreover, we participated in reforming IEC 62321, an
international testing standard published by the International Electrotechnical Commission and used by RoHS, and the commission adopted our halogen-free combustion ion chromatography method in as IEC 62321-3-2, which was published in June 2013.
In 2017, we became
the first display panel company to receive the SGS Eco Label accreditation for OLED television display modules from SGS, a global product testing/accreditation agency, and have since continually received such accreditation. In 2024, such
accreditation has been updated to SGS EEPS accreditation. In 2022, we expanded our accreditation program to cover display modules for monitors, notebook computers, tablets and automobiles, as a result of which our display modules for
monitors and notebook computers received SGS Eco Label accreditation for the first time and our automotive display module became the first in the industry to receive the same accreditation for its excellence in energy efficiency, and we have since
maintained the SGS Eco Label for such products. In 2023, our high-end LCD panels for 16-inch notebooks and 27-inch monitors, in
which we incorporated recycled materials for the first time, received the SGS Eco Label accreditation. In addition, our 30-inch and 55-inch transparent display products,
for which we applied hazardous substance reduction technology, became the first in the industry to receive the SGS Eco Label accreditation. Moreover, in 2022, our 27-inch monitor display product that applied
anti-bacterial films received the SGS Performance Mark accreditation for its anti-bacterial performance, and in 2023, our commercial display module that applied Plus-Bright energy consumption reduction technology obtained the SGS Performance Mark
accreditation for its energy efficiency performance. Our high-end LCD panels for 16-inch notebooks and 27-inch monitors also
received the same accreditation for reducing energy consumption through the implementation of proprietary algorithms and improving panel transmittance.
Also in 2022, upon assessment and verification of GHG emissions throughout its entire product life cycle, our OLED TV panel received the
industrys first Carbon Footprint Certification from The Carbon Trust, a not-for-profit company founded by the United Kingdom government that provides voluntary
carbon certification services and carbon labeling schemes. In 2023, our high-end IT LCD panels (27-inch and smaller) received the Product Carbon Footprint (PCF)
certification from TÜV Rheinland, a global independent testing, inspection and certification agency, by achieving carbon emission reduction through the application of recycled materials and low energy consumption technologies. Our OLED panels
for automotive products also received the same certification for achieving carbon emission through the application of light-control film integration technology.
