Etsuko Kimura is a prominent inventor based in Hitachi, Japan. She has made significant contributions to the field of liquid crystal display (LCD) technology. Her innovative work has led to the development of a patented method that enhances the performance and reliability of LCD devices.

Latest Patents

Etsuko Kimura holds a patent for a liquid crystal display with supplemental capacitors. This invention involves the formation of first pixel electrodes and scan signal electrodes in the same plane. The first pixel electrodes and video signal electrodes are insulated and separated from each other by gate SiN films. Additional capacitors are created using second pixel electrodes, which connect to the first pixel electrodes through apertures formed in the gate SiN films. These apertures can be cut by a laser beam, preventing short circuit defects between the electrodes. This design results in a highly reliable additional capacitor, reduces wiring breakage, and improves the aperture factor by expanding the width of the first pixel electrode. Consequently, a multi-tonality and highly fine liquid crystal display device can be manufactured with a high yield.
