Latest Patents

Matsunami's latest patents include a driving method, drive IC, and drive circuit for liquid crystal displays. His innovations aim to provide a compact and inexpensive LCD by enhancing a drive method that compensates for crosstalk. This is achieved by adding a compensating pulse to the signal voltage, which reduces the size of the drive IC and the periphery of the LCD panel. The method involves adding either a positive or negative compensating pulse based on a predetermined period. Alternatively, two compensating pulses can be added at different times within one horizontal scanning period. The compensating pulse is designed to have a waveform that includes low-frequency components, and its width or height can vary depending on factors such as the location of the signal electrode and the display pattern.
