  • Patent number: 9341762
    Abstract: 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.

  • Publication number: 20160109989
    Abstract: A display device includes a display panel, an electromagnetic touch panel, and a backlight module overlapping one another. The backlight module has a light guide plate and a light source module consisting of a flexible circuit board strip. The flexible circuit board strip includes a light source section and a signal transmission section extending along a light entrance edge and a side edge adjacent to the light entrance edge of the light guide plate, respectively. Two ends of a connection section are connected to the light source section and the signal transmission section, respectively. The connection section includes at least one first fold making the light source disposing plane of the light source section and the wiring disposing plane of the signal transmission section be non-coplanar and also makes the wiring disposing plane be parallel to the plane of the side edge of the light guide plate.

  • Patent number: 8353614
    Abstract: 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.
