Latest Patents
One of his latest patents is a liquid crystal display with an in-cell touch panel that prevents display defects during touch detection. This invention includes a memory liquid crystal display featuring a liquid crystal panel with a built-in touch panel. It is equipped with a state control circuit that switches the state of a pixel electrode between a floating state and a non-floating state. A pulse signal for touch detection is supplied to a common electrode during the touch detection period. The state control circuit changes the pixel electrode's state from non-floating to floating before the touch detection period begins and reverts it back after the period ends.
Another notable patent is an electronic device equipped with a position detector and a touch position detection method. This invention allows for high-accuracy touch position detection, even as thickness reduction in devices progresses. The method includes several determination steps to analyze mutual capacitance detection data and correct it based on self-capacitance detection data, ultimately specifying the touch position accurately.
