Title: Innovations by Kunizo Ogoshi: A Pioneer in Display Technology

Introduction

Kunizo Ogoshi, an esteemed inventor based in Yonezawa, Japan, has made significant contributions to the field of display technology. With a remarkable portfolio of five patents, Ogoshi's work has focused on enhancing the functionality and efficiency of display apparatuses, particularly through innovative manufacturing methods involving piezoelectric elements and organic electroluminescent materials.

Latest Patents

One of Ogoshi's latest patents details a method for manufacturing a display apparatus equipped with a surface acoustic wave (SAW) touch sensor. This innovative technique involves patterning first electrodes in the form of stripes on a transparent substrate's first major surface. Following this, piezoelectric elements that function as the SAW touch sensor are formed on the substrate's second major surface. Ogoshi's method ensures that the formation of light-emitting elements occurs after the piezoelectric elements have been created, thereby protecting the light-emitting elements from heat damage during the manufacturing process.

Another notable patent is for an organic electroluminescent display device. This device comprises organic electroluminescent films, sandwiched between pairs of electrodes, forming various light-emitting elements above a substrate. Each pixel within the display is made up of two differently colored light-emitting elements. The chromaticity of the displayed colors can be controlled by adjusting the concentration of the organic materials or by incorporating additional materials. This capability allows for the production of high-quality quasi-color images through the effective mixing of colors, enhancing the overall display quality with a simplified manufacturing process.
