With a total of 3 patents to his name, Kang continues to push the boundaries of innovation in this rapidly evolving industry.

Latest Patents

One of his latest patents focuses on an organic light-emitting diode display. This invention includes a pixel that features a capacitor coupled to a transistor, with a first insulating layer over the semiconductor layer of the transistor. Additionally, there is a second insulating layer over the first insulating layer, and a blocking layer positioned between the two insulating layers. The design ensures that the first plate of the capacitor is on the first insulating layer, while the second plate is on the second insulating layer. Notably, the blocking layer may be composed of a natural oxide layer, and the first insulating layer can be made from a different material than the blocking layer.

Another significant patent involves a display driving apparatus and a method for driving the display apparatus. This invention is designed to output control signals to multiple driver integrated circuits (ICs) connected in a cascade manner. When a first control signal is input to the first driver IC, a corresponding transmission signal is sent to the subsequent driver IC using this cascade method. The display driving apparatus also includes a restoration signal generation unit, an error detection unit for identifying abnormal driver ICs, and a restoration signal output unit to address any issues with the malfunctioning ICs.
