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
