Title: The Innovative Contributions of Sang Kug Han
Introduction
Sang Kug Han is a notable inventor based in Gwangju, South Korea. He has made significant contributions to the field of display technology, holding a total of 4 patents. His work focuses on improving the performance and efficiency of thin film transistors and liquid crystal display devices.
Latest Patents
One of his latest patents is for a thin film transistor (TFT) of a display apparatus. This invention aims to reduce leakage current caused by a hump and decrease screen defects. The TFT design includes an active layer and a first gate electrode with a gate insulator in between. Additionally, it features a source electrode and a drain electrode positioned at both ends of the active layer. The gate electrode branches into multiple lines and overlaps the active layer. The active layer consists of one or more channel areas between the source and drain electrodes, along with dummy areas and link areas that connect the channel areas in a unified pattern. The length of each dummy area extends from the edge of the corresponding channel area.
Another significant patent involves a liquid crystal display device. This device incorporates dual gate transistors at the output portion of the shift register, which is responsible for outputting a gate voltage. This innovation reduces the charge/discharge time of the output portion, thereby improving the response time of the liquid crystal.
