Patent number: 11300723Abstract: Backlight module, light guide plate, and preparation method for conductive hydrogel thereof. Main body of light guide plate is optical-glass material. Cavity is provided in light guide plate, filled with conductive hydrogel. Either end of light guide plate is provided with electrode electrically connected to conductive hydrogel in cavity. When not electrified, conductive hydrogel is in liquid state, when electrified, conductive hydrogel in cavity changes to gel state. Microcrystal particles are added to conductive hydrogel to improve light refection function and light diffuse reflection function of light guide plate and backlight module, to allow more light rays to penetrate through light guide plate to improve luminous efficacy. Addition of quantum dots or fluorescent powder to conductive hydrogel can further increase color gamut of backlight, such that liquid crystal display device has better effect.Type: GrantFiled: December 20, 2019Date of Patent: April 12, 2022Assignee: Shenzhen TCL New Technology Co., Ltd.Inventors: Honglei Ji, Tianying Deng, Kewen Qiang, Xijun Chen

Patent number: 11181773Abstract: A backlight module. The backlight module comprises: an LED chip (1), a transparent support (2), and a packaging adhesive (3); an accommodating groove (21) is provided on the transparent support (2), and the LED chip (1) is provided at the bottom of the accommodating groove (21); the packaging adhesive (3) is located in the accommodating groove (21) and covers a light-exiting surface of the LED chip (1). The LED chip (1) and the packaging adhesive (3) are provided in the accommodating groove (21), so that the transparent support (2) and the packaging adhesive (3) enlarge a light-exiting angle of the LED chip (1), thereby reducing the number of the LED chips (1) in the backlight module and reducing the production costs.Type: GrantFiled: December 17, 2019Date of Patent: November 23, 2021Inventors: Zelong Li, Daiqing Wang, Kewen Qiang, Honglei Ji

Patent number: 10616659Abstract: Disclosed is a television color cast adjustment method, including: dividing a television display screen into a plurality of areas according to a predetermined manner; determining an adjustment coefficient of red light and an adjustment coefficient of blue light in each area according to a position of each area relative to a light bar for the television display screen; adjusting initial image in each area according to the adjustment coefficients of red light and blue light thereof, and displaying the adjusted image in each area on the television display screen. Disclosed is also a television color cast adjustment apparatus. The present disclosure may solve the problem that the color cast appears on television display screens which is caused by the glass light guide plate, thus the viewing effect of TVs is improved.Type: GrantFiled: December 27, 2016Date of Patent: April 7, 2020Assignee: SHENZHEN TCL NEW TECHNOLOGY CO., LTD.Inventors: Shubiao Liu, Jianyuan Lin, Honglei Ji, Dongcan Zhang, Erchao Yang, Jianshun Huang, Chonghui Luo

Patent number: 10378950Abstract: The invention relates to a measuring device for measuring the mass of a weight, comprising a main frame, a main beam supported on the main frame and comprising a central knife and two side knives parallel with the central knife; a balancing system loaded on one end of the main beam and comprising a set of counterweights; a weighting system loaded on the other end of the main beam; a weight transportation system capable of transporting and loading a standard weight or a test weight into the weighting system and capable of unloading and transporting them away from the weighting system; and a control system. The central knife and the two side knives are made from metal with a high temperature-cryogenic cycling process. The central knife and the two side knives are configured to be adjusted in parallelism with a three-coordinates measuring machine. The control system is adapted to control the balancing system and the weighting system to synchronously load or unload the balancing system and the weighting system.Type: GrantFiled: October 12, 2016Date of Patent: August 13, 2019Assignee: NATIONAL INSTITUTE OF METROLOGYInventors: Jian Wang, Changqing Cai, Xiaoping Ren, Tao Li, Manhong Hu, Xiaolei Wang, Honglei Ji, Xiang Wang, Ping Chen
