Prize for inventing a high-brightness, high-image-quality projector using laser light source –
Seiko Epson Corporation (TSE: 6724, “Epson”) announced that, “The Invention of a High-Brightness, High-Image-Quality Projector using Monochromatic Laser Light Source (Japanese Patent No. 5928569)” has received the Prime Minister’s Prize at the National Commendation for Invention 2021 (sponsored by the Japan Institute of Invention and Innovation).
This is the second time that Epson has received this prize since 1974, when Epson received this prize for Japanese Utility Model Registration No. 957711 for “The Invention of a Device for Correcting the Date and Day of the Week of a Calendar Watch.”
A ceremony will be held on June 22 at The Okura Tokyo, Minato Ward, Tokyo. The National Commendation for Invention*1 are awarded by the Japanese Imperial Family*2 and are intended to contribute to the improvement of science and technology and the development of the industry.
The award honores those who have completed or implemented inventions in Japan and those who have contributed to the promotion of inventions. The winner of the best invention or design receives the Imperial Invention Prize, followed by the Prime Minister’s Prize.
The invention that was the subject of the prize this time is a technology that generates red, green, and blue projection light using laser light and the phosphor wheel. In addition, the laser light is digitally blinked to enable brightness adjustment while preventing flicker from appearing in the projection image. By adopting this technology, we have achieved high brightness and high image quality for laser projectors.

Commenting on the achievement, Takashi Toyooka it’s a great honor for him to have created a projector with high brightness and high image quality using this invention and other technologies, and to have been able to contribute to the development of new image expressions such as projection mapping and digital art.
“We believe this prize is recognition for the image technology developed by Epson through the effort of our many colleagues. We will continue to pursue value from large-screen images and the beauty of light, and we will continue to develop technology that enriches communities,” said Takashi Toyooka.
Another awardee Makoto Zakoji said it is a great honor to receive the Prime Minister’s Prize. “Creating a laser projector that includes the present invention meant we had to build a new product from the bottom up, from basic development through to the commercialization stages,” said Makoto Zakoji.
“It was tough overcoming some of the issues, but I think this prize acknowledges that laser projectors have now become more widespread worldwide. I’m delighted that the hard work of all our colleagues have been recognized in this way. We will continue to work to develop technology that will help bring projectors closer to people and make them more user-friendly,” said Makoto Zakoji
Compared with lamp light source models, laser projectors have higher brightness, longer operating life, and smaller size, thus reducing environmental impact. Illumination is instantaneous, and they can project from various angles so there are no restrictions on the installation angle meaning they are handy for projecting on the ceiling or floor. In addition, the use of this technology makes it easy to digitally adjust the brightness of the projected image, making it very convenient for various environments.
