Latest Patents
One of his latest patents is a driver circuit for driving liquid-crystal displays. This driver circuit operates by inverting the voltage polarity, which results in reduced power consumption. It includes a driving voltage selector circuit that features positive and negative driving voltage selector circuits arranged alternately. The circuit conducts a change-over operation between two states, allowing for efficient signal output during different horizontal periods.
Another notable patent is a circuit for driving a liquid crystal device. In this design, the least significant half of a given image data is decoded by a sub decoder. A sub switch circuit selects one interpolating voltage from multiple options based on the decoded result. This voltage is then applied across a capacitor. The most significant half of the image data is decoded by a main decoder, which selects a main voltage from a variety of main voltages. This innovative approach allows for the generation of multiple output driving voltages corresponding to various gray scale levels, all while minimizing external voltage supplies and costs.
