Latest Patents
Watanabe's latest patents include a liquid crystal display device and a projection type cathode ray tube device. The liquid crystal display device aims to provide high brightness while eliminating brightness irregularities on the display surface. It achieves this by preventing degradation of display quality caused by undesired electric fields during inverter driving of cold cathode fluorescent lamps in the backlight. The design features a plurality of cold cathode fluorescent lamps arranged along the short axis of the display device, with electrodes alternately connected to high-voltage and ground.
The projection type cathode ray tube device involves a unique arrangement of magnets that differ in magnetizing direction. These magnets are positioned at the upper and lower portions of the funnel-side opening of a deflection yoke. This configuration corrects the deflection distortion of the electric beam, enhancing the focusing performance of the display image on the screen.
