Patent number: 9964278Abstract: A reflecting surface of a reflector has a structure where a plurality of reflecting elements are arranged in rows in an up-and-down direction, and the reflecting elements are arranged as a plurality of sets in a left-and-right direction. The surface of each reflecting element is composed of a curved surface having a horizontal section curvature larger than a vertical section curvature. Thus, a horizontally long light distribution pattern may be easily formed by light reflecting from each reflecting element. Each reflecting element is connected to each of four reflecting elements which are adjacent thereto in the left-and-right direction and are shifted therefrom in the up-and-down direction, through a boundary line extending from a vertical plane in an inclined direction in the left-and-right direction. Thus, the horizontally long light distribution pattern formed by the light reflecting from each reflecting element becomes a bright light distribution pattern having four chipped corners.Type: GrantFiled: June 10, 2016Date of Patent: May 8, 2018Assignee: Koito Manufacturing Co., Ltd.Inventors: Masakazu Matsumoto, Takayuki Suzuki

Patent number: 9964683Abstract: The present disclosure discloses a light guide plate, a backlight module and a liquid crystal module. The light guide plate includes a plurality of light guide blocks; the light guide blocks are doped with scattering particles. Since the light guide plate includes a plurality of light guide blocks, this can simplify the cutting of the light guide plate and the making of grid points. The light guide blocks are doped with scattering particles, so that most of rays incident upon the light guide blocks are scattered in a preset direction and guided to a middle part and the light-far end of the backlight module to compensate the brightness of the middle part and the light-far end, thus making the brightness of the side light type backlight display uniform.Type: GrantFiled: July 24, 2014Date of Patent: May 8, 2018Assignees: BOE TECHNOLOGY GROUP CO., LTD., BEIJING BOE DISPLAY TECHNOLOGY CO., LTD.Inventors: Yu Zhang, Wenwen Ma, Lili Jia, Qing Ma, Daekeun Yoon
