Title: The Innovative Mind of Yuuki Ohta

Introduction

Yuuki Ohta, an accomplished inventor based in Osaka, Japan, is recognized for his significant contributions in the field of display technology. With a total of three patents to his name, Ohta's work focuses primarily on enhancing the performance and reliability of liquid crystal display (LCD) devices.

Latest Patents

Among Yuuki Ohta's latest patents is a novel shift register and liquid crystal display device designed for detecting anomalous sync signals. This innovative display panel drive circuit includes a shift register made up of unit circuits arranged in sequences. These unit circuits are responsible for generating signal line selection signals, which become active for designated periods to form pulses that are sequentially output from the first stage to the last stage.

In one embodiment, each unit circuit receives clock signals created from an external sync signal, a start pulse signal based on the sync signal, or signal line selection signals from different stages. Notably, a clear signal becomes active if an anomaly is present in the sync signal, ensuring that no pulse is output from the shift register until the next vertical scanning period commences. This design effectively prevents display disorder and minimizes the load on power sources during sync anomalies.

Another noteworthy patent from Ohta is a display device aimed at reducing parasitic capacitance through the inclusion of a dummy scan line. This device comprises a gate driver with multiple shift register stages corresponding to each row, which generates the necessary gate signals to activate row switching elements. To optimize performance, a dummy line is utilized for the outermost row where scanning begins, driven by a gate start pulse fed into the shift register.
