Title: Hidetaka Kodama: Innovator in Liquid-Crystal Display Technology
Introduction
Hidetaka Kodama is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electronics, particularly in liquid-crystal display (LCD) technology. With a total of 9 patents to his name, Kodama continues to push the boundaries of innovation in his field.
Latest Patents
Kodama's latest patents include a liquid-crystal display driving circuit and method. This innovative driving circuit for an active-matrix liquid-crystal display short-circuits at least two of the signal lines during transitions of signal-line potentials. This design allows for the recycling of charge stored in the parasitic capacitances of the signal lines, thereby reducing the current consumption of the driving circuit. Additionally, when alternating-current driving is employed, current consumption can be minimized by lowering the frequency at which signal lines are driven from one side of a center potential to the other.
Another notable patent is an integrated circuit that comprises a circuit block whose power supply is controlled by a waiting operation. This integrated circuit is designed to prevent the occurrence of penetrating electricity caused by unstable signals output from the circuit block when the power supply is interrupted. In this design, a mask signal is set at 'L' level before the power in the circuit block is broken. A latch circuit formed by a NAND and an inverter maintains a node in 'L' state, ensuring that even if an unstable mask signal is output, the node remains in 'L' level, keeping gate circuits off.
