Title: Innovations of Shiho Hiroshima
Introduction
Shiho Hiroshima is a notable inventor based in Tokyo, Japan. She has made significant contributions to the field of electronics, particularly in display technologies. With a total of 3 patents to her name, her work has garnered attention in the industry.
Latest Patents
One of her latest patents is the "Back to back pre-charge scheme," which describes a circuit for a flat panel display capable of displaying images. This circuit includes an image storage block for storing the images to be displayed, a display and timing controller block controlling the display operation, and an image pixel matrix containing a multitude of rows and columns arranged pixel elements. The circuit also features one or more controlled row driver blocks, one or more controlled column driver blocks, and a pixel pre-charge mechanism for pre-charging the pixel elements using a back to back pre-charge operation applied to a row and/or column drive activated pixel element display operation. The back to back pre-charge operation signifies that during every other operating sequence, a pre-charge operation is replaced by an activated pixel element display operation.
Another significant patent is the "Driver chip based OLED module connectivity test." This invention involves an anode driver chip and a cathode driver chip attached to an OLED device by means of anisotropic glue. The fine structure of the attachment requires inspection to determine any resulting open and short conditions. The anode driver circuits comprise an output current detection that allows open circuit testing of the contact between the OLED device and the anode driver chip. The cathode driver circuits include a voltage detection circuit that allows both open and short circuit detection between cathode driver pads.
