Latest Patents
One of Ohta's latest patents is a method of driving image displays. This invention includes a driving device that performs pulse width modulation drive, effectively restraining power consumption while producing a high-quality multi-tone display. The design ensures that the difference between the scan line voltage and the signal line voltage is equal during both positive and negative polarity writing. This innovation allows for AC-driven pixels, ensuring that the on-resistances of transistors remain equal. By determining the maximum pulse width and the size of switching elements to match positive polarity writing, Ohta's method eliminates the need for a high-frequency clock, thereby reducing power consumption.
Another notable patent involves a liquid crystal panel that includes scanning signal lines for supplying scanning signals to gate electrodes of thin-film transistors (TFTs) and data signal lines for supplying data signals to data electrodes of TFTs. This liquid crystal panel is designed to operate at a rewriting frequency of no more than 30 Hz, allowing it to maintain desirable display quality while consuming low power.
