Patent number: 9341762Abstract: A reflective back cover made of plastic material having micro cellular structures is processed by compression molding and cutting so as to have a monolithical structure. The white material of the reflective back cover reflects lights such that the back cover can be an integral component featuring multiple functions of various components. With the thickness control of the reflective back cover, a concave can be formed at the side of the back cover where a light source is contained and the concave further retains the light source and its flexible printed circuit board. With the incorporation of the reflective back cover, the thickness of the backlight module can be reduced and a reliable and repetitive manufacturing of the backlight module can be introduced.Type: GrantFiled: July 18, 2014Date of Patent: May 17, 2016Assignee: AU Optronics Corp.Inventors: Yu-Yu Chen, Chih-Liang Pan, Yen-Po Yeh

Patent number: 8353614Abstract: A backlight unit includes a light guide plate and a plurality of light sources. A side of the light guide plate is provided with an optical microstructure including a plurality of convex lens members aligned along the side. The height-to-pitch ratios of the convex lens members in the central region of the optical microstructure are different from those of the convex lens members in the side regions of the optical microstructure. For example, the height-to-pitch ratios of the convex lens members in the central region of the optical microstructure are larger than the height-to-pitch ratios of the convex lens members in the side regions of the optical microstructure. The light sources may be light emitting diodes (LED) directed toward the optical microstructure.Type: GrantFiled: January 21, 2010Date of Patent: January 15, 2013Assignee: AU Optronics CorporationInventors: Chih Liang Pan, Shau Yu Tsai, Yen Po Yeh, Yu Hsiu Chang
