BASF, the world’s leading chemical company, and CLAP, a Korean optical film manufacturer, have signed a technology transfer and license agreement regarding an optical film technology for coating OLED Under Panel Sensors (UPS). The UPS technology can maximize the display area for mobile devices, with all sensors being hidden under the display.
The agreement enables CLAP to manufacture optical films using BASF’s Liquid Crystal (LC) materials and coating technology to deposit films with retardation and polarization properties, which can be patterned according to optical design requirements. CLAP’s UPS film – a thin, coated, patterned film-stack – can solve the internal noise problem from reflected light, that occurs when installing optical sensors under panels to develop notch-less full-screen OLED smartphones. Micro-patterning enables customized light management that is required for designing the sensors.
Signing ceremony was held at BASF Korea office on Jun 25th. From the left: Mason Seung - CEO of CleanWrap, SungHo Kim - CEO of CLAP, Dr. Lothar Laupichler, senior vice president of BASF's Global Electronic Materials Business, Young-Yull, Kim – Representative Director of BASF Korea
“As a film manufacturer with excellent expertise in display applications, CLAP is the preferred partner that can effectively commercialize BASF’s LC technology for sensor applications” said Lothar Laupichler, Senior Vice President of BASF's Global Electronic Materials Business. “Our LC material technology, accumulated over years of research and experience, is the ideal solution to improve the sensitivity of smartphone sensors. Combined with CLAP’s film and device technology, we will be able to provide a reliable solution to customers in the display market.”
“BASF’s superior functional light control materials will help to solve the problem that occurs in under panel optical sensors and further contribute by providing high-quality products,” said CLAP CEO Kim Sung-Ho. “The unique technology is an enabler for notch-less displays.”
Seung Moon-Soo, CEO of CleanWrap, a Korean food packaging product manufacturer, and also the parent company of CLAP, said, “We target a sustainable and innovative product portfolio, and believe BASF’s unique technology and product portfolio will provide an ideal fit to address consumer’s needs in the electronic market and beyond.”
CLAP – a subsidiary of Korean food packaging product manufacturer CleanWrap – specializes in display and sensor technologies derived from the expertise of its management who have accumulated more than 30 years of experience in the field. Based on its experience in the display design and optics field, CLAP plans to produce optical films for OLED polarizers as well as Under Panel Sensors (UPS), in addition to its initiatives to develop full screen fingerprint recognition solutions using printed electronics technologies.
