Title: Ha-Jun Lee and Display-Driving Circuit Innovation.
Introduction
Ha-Jun Lee is an inventor associated with Seoul, South Korea, and Samsung Electronics Co., Ltd. His listed patent work concerns circuitry designed to improve the signals that drive display devices.
Latest Patents
Lee is credited with 1 patent: “Output Buffer Circuit and Source Driving Circuit Including the Same.” The invention describes an output buffer circuit that compensates for the slew rate of signals used to drive a display. A bias-current control signal generating circuit performs an exclusive OR operation on an input signal and the output of a reference operational amplifier. A channel amplifying circuit then uses that control signal to adjust the slew rate of multiple output voltage signals, which control the display device.
Career Highlights
Lee’s listed patent reflects work on source-driving circuitry and signal control for display technology. The patent identifies Samsung Electronics Co., Ltd. as his company.
Collaborations
Jin-han Kim and Jae-Wook Kwon are listed as Lee’s coworkers. The available information does not specify their roles in the patent.
Conclusion
Ha-Jun Lee’s listed invention focuses on controlling output-buffer slew rates to support the operation of display-driving circuits.
