Company profile
researched Aug 2026Lapto (LAPTO Co., Ltd., λ©ν ) is a South Korean materials company that develops new organic light-emitting diode (OLED) materials for the display industry. Its technology portfolio spans capping layer (CPL) materials in both high- and low-refractive-index variants, CPM materials, electron transport layer (ETL) materials, and phosphorescent and TADF emitter dopants. The company describes its core aim as improving overall display efficiency through material-level innovation, and states it has developed CPL materials with improved refractive index that raise OLED display efficiency.
The company operates its own certified corporate R&D center, equipped with evaporator tooling from Sunic System (installed 2015) and Selcos (second unit, 2020), and positions this infrastructure as the basis for developing next-generation OLED materials and devices. Lapto reports filing roughly 100 patent applications in Korea and abroad, of which more than 30 are registered. Several filings are joint: two platinum-based red dopant applications and four TADF green dopant applications with Samsung Display, and two ETL material applications with LG Display.
Lapto is headquartered on the 11th floor of Halla Sigma Valley, 545 Dunchon-daero, Jungwon-gu, Seongnam-si, Gyeonggi-do, Korea, and is led by President and CEO Tae-young Kwak. Its website carries sections for investor relations, public disclosures, press releases and recruitment.
Business model
Lapto develops and supplies OLED materials to display manufacturers, working under development contracts with large Korean corporates (for example a phosphorescent red dopant development contract in 2016 and a TADF green dopant development contract in 2018) and moving qualified materials into mass production and supply, as it did with high-refractive CPL material from 2019.
Traction
Approximately 100 patent applications filed domestically and internationally with more than 30 registered patents; mass production confirmed and supply started for high-refractive CPL material with a Korean conglomerate in 2019; development contracts for phosphorescent red dopant (2016) and TADF green dopant (2018); registration on the K-OTC market in 2020.
Latest developments
In 2020 the company registered on the K-OTC market under item code 366130, added a second Selcos evaporator, and began research and development on CPM material; research on low-refractive-index CPL material started in 2019.

Market position
The company positions itself as an OLED materials specialist aiming to become a world-leading supplier in the field, with joint patent filings alongside Samsung Display and LG Display and supply of high-refractive CPL material to a large Korean customer.
Technology
Lapto focuses on OLED material chemistry: capping layer (CPL) materials engineered for improved refractive index in both high- and low-refractive forms to raise OLED display light-output efficiency, CPM materials, electron transport layer materials, and emitter dopants including platinum-based phosphorescent red dopants and thermally activated delayed fluorescence (TADF) green dopants. Development is supported by in-house evaporator equipment for device fabrication and evaluation.
Go-to-market
OLED display panel manufacturers, including large Korean conglomerates; joint patent activity is disclosed with Samsung Display and LG Display.
Geography
Headquartered in Seongnam-si, Gyeonggi-do, South Korea, with patent filings both domestically and abroad.
History
The company was established in 2011 as WS Co., Ltd. with capital of KRW 2 billion. It secured KRW 1.5 billion of investment from Atinum Investment and Korea Investment Partners in 2012, and KRW 8.6 billion from Korean investors including Hanwha Investment in 2014, the same year its corporate-affiliated R&D center was certified. In 2015 it began R&D on a CPL backbone and completed installation of its first Sunic System evaporator. It was renamed LAPTO Co., Ltd. in 2016 and contracted development of a phosphorescent red dopant with a Korean conglomerate. R&D on ETL and high-refractive CPL materials began in 2017, a TADF green dopant development contract followed in 2018, and in 2019 the company confirmed mass production and began supplying high-refractive CPL material to a Korean conglomerate while starting research on low-refractive CPL. In 2020 it registered on Korea's K-OTC market (item code 366130), warehoused a second Selcos evaporator, and began R&D on CPM material.
