Latest Patents

One of his latest patents is a method of fabricating a fringe field switching liquid crystal display device. This innovative method prevents inferior connections between the drain electrode and the pixel electrode by avoiding the formation of a copper compound on the drain electrode. It achieves this by performing back channel etching after patterning the pixel electrode and utilizing a wet strip instead of a dry strip. This process results in direct contact between copper and ITO, thereby reducing the number of mask processes required.

Another notable patent is related to a thin-film transistor and its fabrication method in a liquid crystal display device. This invention includes a first gate electrode formed on an insulating substrate, a first gate insulation film, an active layer, and source/drain electrodes. The design allows for a second gate insulation film with a contact hole that exposes part of the drain electrode, facilitating an efficient connection to the pixel electrode.
