Patent number: 8780297Abstract: The present invention discloses a backlight module which has a plurality of light-emitting diodes. The light-emitting diodes are divided into a plurality of light groups according to pitches between the adjacent light-emitting diodes. The light-emitting diodes with respect to a display-area center line have a position center, and the light group having the light-emitting diodes with larger pitches therebetween is in a position relatively close to the position center and is in a higher bright bin; the light group having the light-emitting diodes with smaller pitches therebetween is in a position relatively away from the position center and is in a lower bright bin. Therefore, luminous conditions of the overall light-emitting diodes tend to correspondence, and proportion of usage of light-emitting diodes in different bright bins can be increased.Type: GrantFiled: November 9, 2010Date of Patent: July 15, 2014Assignee: Shenzhen China Star Optoelectronics Technology Co., Ltd.Inventors: Qian Cao, Poying Lin

Patent number: 8702293Abstract: The present invention provides a light guide plate and a backlight module, wherein the light guide plate comprises a bottom surface, a light incident surface and a light-emitting surface. The light-emitting surface and the bottom surface are positioned oppositely. The bottom surface comprises a plurality of screen dots. The screen dots comprise fluorescent powder and are selectively added with diffusion particles. The present invention prevents the phenomenon of color shift and the luminous efficiency degradation due to the fluorescent powder accelerated ageing because of closing to the LED chip.Type: GrantFiled: November 26, 2010Date of Patent: April 22, 2014Assignee: Shenzhen China Star Optoelectronics Technology Co., Ltd.Inventors: Jianfa Huang, Poying Lin

Publication number: 20130063927Abstract: The present invention discloses a LED backlight module and a LCD device, wherein said LED backlight module comprises a reflector, multiple LEDs arranged on the reflector and a diffuser plate arranged oppositely to the LEDs; said diffuser plate is provided with multiple uniform-lighting structures. Because the diffuser plate of the LED backlight module of the present invention is provided with the uniform-lighting structures, the distance of light mixing and the light diffusion effect are increased through the reflecting and scattering effects of the uniform-lighting structures. Thus, the direct light backlight module is thinned, the number of LEDs is reduced, and the mura phenomenon is reduced.Type: ApplicationFiled: September 23, 2011Publication date: March 14, 2013Inventors: Poying Lin, Jie Ren
