Latest Patents
One of his latest inventions is a liquid crystal video display device. This invention is directed to an improved liquid crystal video display device. An interlacing video display technique is utilized, and scanning signals are provided to every other scanning electrode line in sequential order, shifting selected lines every frame. An additional selected voltage is provided during the time period which overlaps the selected scanning electrode lines to the adjacent non-selected electrodes both above and below the selected scanning electrode lines. According to the invention, a high-resolution display is provided while reducing associated flicker by driving all scanning lines in the desired order. Another notable patent is the multi-alarm electronic watch. This multi-alarm watch includes a liquid crystal display means for providing both conventional time displays and an alarm time schedule display indicating simultaneously a plurality of times of day scheduled for an alarm signal. Separated or overlapped displays are used. The displays are driven by AC multiplexed voltage signals, with each display having a different duty cycle. A random access memory stores data for the scheduled alarm circuitry and display. For greater visibility, the scheduled display shows alarm times for twelve hours at one time, and an address decoder converts timekeeping signals into a memory address code for the alarm schedule. A conventional alarm is also provided, and distinctive audible signals identify different functional outputs.
