Latest Patents

Minoura’s latest listed patents focus on improving the performance and uniformity of display illumination.

“Lighting Device and Display Device” describes a backlight assembly with LEDs, a light guide plate, an LED board, and a light-blocking portion. The light guide plate receives light through an entrance surface and emits it through a plate surface. A portion of the LED board overlaps the plate near its light entrance, while the light-blocking portion is positioned between the overlapping board and the light guide plate’s edge. This arrangement manages light around the entrance area.

“Illuminating Device and Display Device Provided with Same” addresses uneven brightness in a backlight. A diffusion sheet covers both the bottom of an optical sheet and an area of the light guide plate between the LED flexible printed circuit board and the optical sheet. The sheet diffuses light that escapes from the light guide plate before it reaches the liquid crystal display panel, helping make screen brightness more uniform regardless of distance from an LED.

Career Highlights

Minoura’s listed inventions concern optical components used in display illumination. His work addresses how light enters, travels through, and exits a light guide plate, as well as how leaked light can be diffused to improve screen brightness.
