Latest Patents
Hai Sung Park holds a patent for a "Method of fabricating liquid crystal display." This method utilizes a negative photo-resist to create a liquid crystal display. The process involves forming a passivation layer on a transparent substrate, which covers a thin film transistor, a data line, and a gate line. The passivation layer is then patterned to define a contact hole that exposes a drain electrode. Following this, a transparent conductive film is formed in electrical contact with the drain electrode via the contact hole. A negative-type photoresist is coated on the transparent conductive film, which is then exposed with an image of the desired pixel electrode. The negative-type photoresist is developed to expose portions of the transparent conductive film over a data line, a gate line, and the area of the thin film transistor. Finally, the exposed transparent conductive film is etched. This innovative approach enhances the efficiency and quality of LCD fabrication.
