Patent number: 11428986Abstract: A direct-type light source module including N-stage light sources and an optical sheet is provided. The optical sheet is disposed above the N-stage light sources, and an optical distance between the i-th-stage light source and the optical sheet is smaller than an optical distance between the i+1-th-stage light source and the optical sheet, where 1?i<N, and N is a positive integer greater than 1. A display device is also provided.Type: GrantFiled: August 2, 2021Date of Patent: August 30, 2022Assignee: Wistron CorporationInventors: Han-Jen Liang, Lei-Ken Hung, Ching-Hsuan Tsai, Wei-Chi Lin, Chih-Chou Chou

Patent number: 8485711Abstract: A light plate includes a light guide plate and four light source modules. The light source modules are disposed around the light guide plate. Each of the light source modules includes a first white light emitting element and a second white light emitting element. The first white light emitting element is capable of emitting a first white beam. The second white light emitting element disposed beside the first white light emitting element is capable of emitting a second white beam. The first white light emitting elements of the light source modules are mirror-symmetrical with respect to a first reference plane and a second reference plane. The second white light emitting elements of the light source modules are mirror-symmetrical with respect to the first reference plane and the second reference plane. The correlated color temperature (CCT) of the first white beam is greater than the CCT of the second white beam.Type: GrantFiled: May 18, 2010Date of Patent: July 16, 2013Assignee: Young Lighting Technology Inc.Inventors: Wei-Chih Wang, Wei-Chun Yang, Lei-Ken Hung

Patent number: 8449163Abstract: A backlight module includes at least one light emitting device capable of emitting a light beam, a light guide plate, and a thermal insulation light guide element. The light guide plate has two surfaces opposite to each other and a side surface connecting the two surfaces. The light emitting device is disposed beside the side surface. The light beam enters the light guide plate through the side surface. The thermal insulation light guide element has a light incident surface and a light emitting surface. The light incident surface having at least one first recess is located in a transmission path of the light beam and between the light emitting device and the side surface. The light emitting surface is disposed between the light incident surface and the side surface. The glass transition temperature of the thermal insulation light guide element is higher than that of the light guide plate.Type: GrantFiled: September 14, 2010Date of Patent: May 28, 2013Assignee: Young Lighting Technology Inc.Inventors: Chiao-Chih Yang, Lei-Ken Hung, Hsin-Tse Tsai, Yi-Yu Tsai

Publication number: 20110292314Abstract: A display apparatus and a backlight module are provided. The display apparatus includes a liquid crystal panel and a backlight module. The backlight module includes a frame, a plurality of latch members, and a backlight source. The frame has a receiving slot. The liquid crystal panel is disposed in the receiving slot. The latch members are disposed on the frame and located at an inner wall of the receiving slot. The latch members support the liquid crystal panel. A material of each latch member is a debris-resistant material. The backlight source is disposed on the frame and located at one side of the liquid crystal panel. The invention may prevent the producing of debris when the latch members and the liquid crystal panel are rubbed against each other.Type: ApplicationFiled: January 27, 2011Publication date: December 1, 2011Applicant: YOUNG LIGHTING TECHNOLOGY CORPORATIONInventors: Peng-Fang Chen, Shang-Chia Liu, Fan-Ti Cho, Lei-Ken Hung
