Title: Innovations of Hiroyoshi Murata
Introduction
Hiroyoshi Murata is a prominent inventor based in Saitama-ken, Japan. He has made significant contributions to the field of display technology, holding a total of seven patents. His work focuses on enhancing the efficiency and quality of display devices.
Latest Patents
One of Murata's latest patents is a display device equipped with SRAM in pixel and the driving method of the same. This technology aims to reduce manufacturing costs by simplifying the constitution of a driver. The invention converts a write voltage equivalent to white or black, represented by a tone level of a normal display area, into a write voltage corresponding to the brightest white or darkest black display in the pixel. This write voltage is held in the SRAM of each pixel. For normal display, the display operates with the write voltage represented by the tone level of the normal display area. In the case of static image display, the display utilizes the write voltage corresponding to the brightest white or darkest black display, which is also held in the SRAM. This innovation allows both normal and static image displays to be carried out with a write voltage supplied from a single driver, thereby simplifying the driver's constitution.
Another notable patent is the multi-gray level display apparatus and method of displaying an image at many gray levels. This invention is designed to display multi-gray level images without flicker by using a small number of voltages. The display includes a first gray-level pattern generating circuit that acquires a gray level during m frame periods and a second gray-level pattern generating circuit that acquires another gray level during n frame periods, where n is a positive integer greater than m. A selection circuit is employed to select and output one of the preset voltages based on the output from either gray-level pattern generating circuit when the input multi-gray level display data corresponds to a gray level of either pattern.
