Patent number: 10473978Abstract: A light guide assembly for a backlight module is disclosed, comprising a metal element and a light guide element which are integrated together. At least a portion of at least a side surface of the light guide element is used to receive light emitted from a light source to generate backlight, and the metal element surrounds a side surface of the light guide element that is not used to receive light from the light source. In this way, the backlight module can omit the structures such as rubber frame, backplate, and the like, while the overall mechanical strength of the backlight module can be ensured, the thickness of the backlight module can be decreased to meet the requirement on thinning of the display device, and the production and maintenance costs can be reduced.Type: GrantFiled: August 19, 2016Date of Patent: November 12, 2019Assignees: BOE TECHNOLOGY GROUP CO., LTD., BOE OPTICAL SCIENCE AND TECHNOLOGY CO., LTD.Inventors: Xiaoli Xia, Xiaozeng Pei

Patent number: 10139553Abstract: A backlight module and a display device are provided. The backlight module comprises a light guide plate, a sealant frame enclosing edges of the light guide plate, and a light source disposed at an end of the light guide plate. The light guide plate has a near light end near the light source and a far light end further away from the light source. The light guide plate includes at least one first positioning structure at the far light end. The sealant frame includes at least a second positioning structure disposed at a position corresponding to the first positioning structure at the far light end. The first positioning structure and the second positioning structure are engaged with each other to position the light guide plate on a plane parallel to a light emitting surface of the light guide plate.Type: GrantFiled: July 16, 2015Date of Patent: November 27, 2018Assignees: BOE TECHNOLOGY GROUP CO., LTD., BOE OPTICAL SCIENCE AND TECHNOLOGY CO., LTD.Inventors: Jingdan Peng, Wenjun Li, Xiaozeng Pei

Publication number: 20180217314Abstract: A backlight module, a method for assembling the same and a display device are disclosed. The backlight module includes an optical film (11) and a light-shielding tape (12), wherein the light-shielding tape (12) is disposed on n sides of all four sides of the optical film (11), n being a positive integer smaller than 4. By reducing an area of regions covered by the light-shielding tape (12) on the optical film (11) of the backlight module, an area of the viewing region of the backlight module is increased.Type: ApplicationFiled: July 22, 2016Publication date: August 2, 2018Inventors: Xiaozeng PEI, Guangyue HU

Patent number: 9784909Abstract: The present invention discloses a backlight module and a display device, so as to improve the luminous effect of the backlight module. The backlight module includes: a backboard; a seal frame and a light guide plate arranged in the backboard; and a light source assembly located between the light guide plate and the seal frame. The light source assembly comprises a light source and a circuit board for controlling the light source. A bottom surface of the circuit board of the light source assembly abuts against an inner surface of the backboard. Since the bottom surface of the circuit board abuts against the inner surface of the backboard, the heat generated by the light source of the light source assembly may be transferred to the backboard through the circuit board and directly dissipated outside from the backboard.Type: GrantFiled: July 16, 2015Date of Patent: October 10, 2017Assignees: BOE TECHNOLOGY GROUP CO., LTD., BOE OPTICAL SCIENCE AND TECHNOLOGY CO., LTD.Inventors: Xiaozeng Pei, Wenjun Li
