Title: Innovations of Sangyeon Kim in Display Technology
Introduction
Sangyeon Kim is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of display technology, particularly in organic light-emitting diodes (OLEDs). With a total of 2 patents, his work focuses on enhancing the performance and efficiency of display systems.
Latest Patents
Sangyeon Kim's latest patents include innovative designs and methods that improve OLED technology. One of his notable patents is related to a pixel circuit and driving method for OLED displays. This invention provides pixel circuits that utilize organic light-emitting diodes and a driving method that compensates for threshold voltage differences and mobility deviations. The drive transistor in this design is capable of emitting light by generating a drive current, which is adjusted based on reference voltage and data signals. This ensures that the threshold voltage compensation time is adequately set, regardless of the timing of data signals supplied to the pixel circuits.
Another significant patent by Kim is the development of a single input level shifter. This device includes an input unit that applies a power voltage to a first node in response to an input signal. It also features a bootstrapping unit that raises the voltage level of the first node higher than the power voltage when the input signal shifts between voltage levels. This innovation enhances the efficiency and reliability of signal processing in electronic devices.
