Patent number: 9004708Abstract: An apparatus to widen the light dispersion pattern of a light source shining through an overlay window from the viewing side of an electrical computer system. The overlay window is coupled to a panel of the system. The overlay window includes a transparent material, which has a first surface facing the light source and a second surface facing away from the light source to define a viewing side. An opaque material can be disposed on the first surface to partially cover the first surface to form a viewing window. A first diffusing mechanism is disposed on the first surface, and a second diffusing mechanism is disposed on the second surface. In response to the passage of the light output through the viewing window, the light dispersion pattern of the light output from the viewing side of the overlay window has a viewing angle of up to about 180 degrees.Type: GrantFiled: October 14, 2013Date of Patent: April 14, 2015Assignee: Cisco Technology, Inc.Inventors: Perry L. Hayden, Sr., Ronald D. Lutz, Jr., Charles Ingalz, Bill Hin Yi Fong

Patent number: 9004735Abstract: A backlight module includes a light guide plate and only one light source. The light guide plate has a main body and protrusions. The main body has a light emitting surface, a light incident surface, a first side surface, and a second side surface. The protrusions are positioned on the light incident surface, and face the light source. The protrusions diffuse the light rays from the only one light source and guides the light rays into the main body. The light emitting surface has a light emitting area and a marginal area surrounding the light emitting area. The marginal area has a light diffusion area adjacent to the light incident surface and the first side surface. An included angle between the light incident surface and the first side surface is an obtuse angle. An included angle between the light incident surface and the second side surface is an obtuse angle.Type: GrantFiled: April 24, 2013Date of Patent: April 14, 2015Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Po-Chou Chen
