Latest Patents
Mabuchi's latest patents include a light guide plate and a surface light source device, along with a display device utilizing these technologies. The surface light source device features a light guide plate positioned above a liquid crystal panel unit, with a linear light source extending parallel to the side surface of the light guide plate. This design incorporates a series of linear prisms on the upper surface of the light guide plate, which reflect light from the linear light source onto the liquid crystal panel below. The height of the reflecting surfaces of the prisms varies along their length, enhancing the device's performance. Additionally, the surface light source device allows light emitted from the linear light source to be incident on one side of the light guide plate, which then emits light from its upper surface. A display panel covers the light guide plate, featuring two display areas with different translucency rates, while a light-shielding sheet is placed between the light guide plate and the display area to manage light emission.
