Introduction

Mari Funada is a notable inventor based in Kariya, Japan. She has made significant contributions to the field of light-emitting technology, holding a total of 3 patents. Her work focuses on enhancing the efficiency and brightness of light-emitting devices.

Latest Patents

One of her latest patents is a light-emitting apparatus and method for forming the same. In this bottom emission type light-emitting apparatus, the face of a substrate, which is opposite from a light-emitting device, features an uneven surface with multiple asperities. The mean spacing Sm of adjacent asperities or the mean spacing S of peaks of adjacent projections is designed to be no less than three times the longest wavelength of light generated by the light-emitting layer and no more than two hundred times the longest wavelength. The arithmetic mean slope of the uneven surface is maintained between 3° and 20°, resulting in higher extraction efficiency and increased brightness in a specific direction.

Another patent by Funada also pertains to a light-emitting apparatus, where the substrate's face on which the light-emitting device is formed has an uneven surface with numerous asperities. The mean spacing Sm or S is similarly defined, ensuring that it is no less than three times and no more than two hundred times the longest wavelength of light generated. The arithmetic mean slope of this uneven surface ranges between 4° and 30°, allowing the apparatus to emit a greater amount of light from the light extraction side while minimizing brightness unevenness compared to traditional light-emitting devices.
