Latest Patents

One of her latest patents is a liquid crystal display apparatus that allows for the accurate and effective adjustment of white balance based on the measurement of light emission luminance from a backlight. This innovative design includes a backlight luminance detection portion that measures the light emission luminance of an LED backlight while the optical shutter of the liquid crystal display panel is closed. The main control portion then adjusts the light emission luminance of the LED backlight according to the detected values. It compares the light emission luminance of RGB LEDs with pre-stored values for white balance adjustment, making necessary corrections to eliminate any discrepancies.

Another notable patent is for an illumination device and display device that incorporates a light source with multiple light-emitting elements. This device features a luminous intensity controller that manages the luminous intensities of these elements separately, based on a predetermined correction table that indicates temperature distribution characteristics. This innovation allows for precise control of luminous intensities according to the position information of the light-emitting elements.
