Title: Innovations of Inventor Li-Jin Kim
Introduction
Li-Jin Kim is a prominent inventor based in Paju-si, South Korea. He has made significant contributions to the field of display technology, holding a total of 3 patents. His work focuses on enhancing the performance and efficiency of light-emitting display apparatuses.
Latest Patents
One of his latest patents is a "Light emitting display apparatus with driving transistor formed of an oxide semiconductor." This invention includes a pixel that comprises a pixel driving circuit and a light-emitting device. The gate driver supplies gate signals to the pixel driving circuit, which consists of a switching transistor, a driving transistor, and a first light-emitting transistor. The first light-emitting transistor connects the anode of the light-emitting device to a first node, while the driving transistor regulates the current supplied to the light-emitting device. The switching transistor controls the data voltage supply to the light-emitting device. The apparatus operates by dividing one second into a refresh period and an anode reset period, with the switching transistor activated only during the refresh period.
Another notable patent is the "Luminance difference correction method and light emitting display apparatus using the same." This method involves a camera receiving an image from a light-emitting display panel, which is reflected by a reflector or cover glass. The controller analyzes the received image and adjusts the gamma voltage or driving voltages supplied to the pixels in the display panel to correct luminance differences.
