Latest Patents
One of his latest patents is a power supply and reference voltage circuit for TFT LCD source drivers. This invention provides a liquid crystal power supply that generates a high-precision drive power supply voltage for a driver circuit using a low-precision reference voltage generating circuit. The power supply circuit includes a DC/DC converter that generates a voltage based on an oscillation signal from a power supply voltage. It outputs this generated voltage as a drive power supply voltage. Additionally, it features a stabilized power supply circuit that generates a highest-level reference potential for creating a gray-scale voltage in a driver circuit. The circuit also includes a comparison unit that outputs a difference voltage based on the difference between the drive power supply voltage and the highest-level reference potential, along with an internal reference voltage generating unit and an error amplifying unit.
Another significant patent involves a method of converting a linear value to an integer. In this method, a triangle is considered, consisting of the origin and two points. The conversion is accomplished by determining the y-coordinate value of a specific point based on integral lattice points positioned near one side of the triangle in the xy coordinate system.
