Jong Min Lee

Jong Woo Lee is a prolific inventor from Suwon-si, KR, with an impressive 243 patents to his name. Among his latest patents is a switching operation sensing device that distinguishes touch regions on the surface of an integrated housing. This device boasts a touch operation unit that is integrally formed with the housing and includes first and second touch members in different regions. An oscillator circuit generates a first oscillation signal when the first touch member is touched and a second oscillation signal when the second touch member is touched. A touch detector circuit detects whether either touch member has been touched and distinguishes touch regions based on the oscillation signals.

Another recent patent from Lee is for a multilayer ceramic capacitor. This capacitor includes a ceramic body with opposing first and second surfaces connected by third and fourth surfaces. A plurality of internal electrodes are inside the ceramic body, each exposing one end to the third or fourth surface. First and second side margin portions are present on sides of internal electrodes exposed to the first and second surfaces. The dielectric composition of these margin portions is different from the ceramic body’s dielectric composition, and a dielectric constant of the side margin portions is lower than that of the ceramic body.

Lee has worked for companies such as Samsung Electro-Mechanics Co., Ltd., and Samsung Electronics Co., Ltd.. He has collaborated with fellow inventors such as Jang Yeol Lee and Myung Jun Park.

Jong Woo Lee’s inventions have undoubtedly made significant contributions to the electronic industry, particularly in the areas of sensing devices and capacitors. His many patents demonstrate his technical expertise and innovation in these fields.
