Latest Patents

Among his latest patents, Jang has developed an array substrate and a narrow bezel-type liquid crystal display device. This LCD device features a first substrate with a display region that includes pixel regions and a non-display region. The design incorporates gate lines and data lines that cross each other to define the pixel regions, along with a thin film transistor (TFT) in each pixel region. Additionally, the device includes a pixel electrode connected to the TFT, a second substrate opposite the first, a color filter layer, a common electrode, and a liquid crystal layer. Notably, the gate lines have a double structure consisting of a transparent conductive material and a layer of copper or copper alloy.

Another of his recent patents is for an array substrate for a liquid crystal display device. This substrate comprises gate and data lines that cross each other to define a pixel region, along with a common line that is spaced apart from and parallel to the gate line. It also features a thin film transistor connected to the gate and data lines, a passivation layer, and pixel and common electrodes arranged to produce an in-plane electric field. Each of these electrodes has a double-layered structure, with the lower layer made of reflective conductive material and the upper layer of transparent conductive material.
