Latest Patents

One of Il-Man Choi's latest patents is titled "Array substrate for liquid crystal display device and method of fabricating the same." This invention describes an array substrate for an LCD device that includes a gate line crossing a data line to define a pixel region. The design features a thin film transistor (TFT) with a gate electrode connected to the gate line, along with insulating and active layers. The source electrode connects to the data line, while the drain electrode is spaced apart from the source electrode. Additionally, an auxiliary common electrode is incorporated, which includes a horizontal portion within the pixel region. A metal layer overlaps the insulating layer and contacts the horizontal portion of the auxiliary common electrode through a defined contact hole. A passivation layer is placed over the TFT and metal layer, and the pixel electrode has a horizontal portion that overlaps the metal layer, forming a storage capacitor. This innovative design enhances the performance and reliability of LCD devices.

Another notable patent by Choi involves the formation of array substrates for LCD devices on a substrate with first and second gate lines crossing a data line to define pixel regions. This invention includes a thin film transistor with source and drain electrodes, and a metal pattern that overlaps a common line, contributing to the drain electrode. A passivation layer is applied over the source and drain electrodes, and a first pixel electrode connects to the metal pattern. The design also features various repair patterns that allow for the connection of the drain electrode or metal pattern to a second pixel electrode in case of failure, ensuring the display remains functional.
