- 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 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.
In 2021, we received the Green Technology Certification for our advanced incell touch display technology, an eco-friendly technology with touch-sensing electrodes and transmission lines that reduce carbon emissions and the use of rare metals. Also, since 2021, we have continued to obtain an
eco-friendly certification from TUV SUD, a globally recognized accreditation agency, for excellence in resource circulation and non-use of specific hazardous substances
in our OLED television and PO mobile models.
