Introduction

Yojiro Matsueda is a notable inventor based in Suwon-si, South Korea. He has made significant contributions to the field of display technology, holding a total of 3 patents. His work primarily focuses on light-emitting display devices, which are essential in modern electronic displays.

Latest Patents

Matsueda's latest patents include a variety of innovative technologies. One of his patents describes a light-emitting display device that incorporates data lines, signal lines, pixel circuits, a data driver, and a precharger. This device features pixel circuits that consist of a first switch, a transistor, a capacitor, and a light-emitting element. The precharger is designed to supply a precharge current that is a multiple of the data current to the corresponding data line, responding to a control signal. This allows for efficient charging of the capacitor, which subsequently supplies current to the light-emitting element, enabling it to emit light.

Another patent focuses on an emission display that includes data lines, select signal lines, emit signal lines, and pixel circuits. In this design, the first switch transmits a data current from the data line in response to a scan signal, allowing the capacitor to charge a voltage corresponding to the data current. During the display period, the second switch supplies current from the transistor to the emission element, while it is turned off during the non-display period, ensuring no current is supplied to the emission element.
