Executive Vice President Choi has contributed to the development of new display products and technologies for over 30 years. He developed the 'Tandem OLED (Organic Light Emitting Diode)' structure, which stacks two OLED organic emission layers to increase luminance (screen brightness) and extend lifespan. He created a technology that replaces the hydrogen element, a key component of organic light-emitting devices, with heavy hydrogen (deuterium) in a strong and stable structure, significantly extending the OLED lifespan. He played a crucial role in expanding the OLED product lineup from TVs and smartphones to IT and automotive fields.

He also developed LG Display's high-quality LCD (Liquid Crystal Display) wide viewing angle technology (IPS - In-Plane Switching). This improved the narrow viewing angle issue, a drawback of LCDs, contributing to the commercialization of high-performance TV and IT LCD products.

SID stated, "(Executive Vice President Choi) has greatly contributed to the advancement of display technology by developing high-efficiency OLED with a tandem structure and commercializing TV and high-performance IT LCDs."
