  • Patent number: 8876358
    Abstract: Disclosed is a display apparatus which does not use some elements of cases and set cover members necessary for producing the display apparatus and thus can minimize a thickness and enhance a sense of beauty with an innovative design. The display apparatus includes a display panel, a panel supporting member, an adhesive member, a guide frame, and a cover member. The panel supporting member supports a rear edge of the display panel. The adhesive member is disposed at one side of the panel supporting member, and couples the display panel and the panel supporting member. The guide frame supports the panel supporting member. The cover member is disposed to overlap with the other side of the panel supporting member and surround a side surface of the guide frame, thereby enabling movement of the panel supporting member.

  • Patent number: 7993026
    Abstract: The invention disclosed a light source, comprising a light tube and a plurality of prism members disposed on an outer surface of the light tube for reducing amount of external lights entering the light tube. According to the invention, the prism members disposed on the outer surface of the light tube can not only focus the light emitting from the light tube, but also increase the possibility of total reflection of the incident light.

  • Patent number: 7726866
    Abstract: Disclosed is a backlight reflection plate and a backlight module using the reflection plate. The reflection plate encloses a light source. The reflection plate comprises a reflection substrate with a surface facing the light source. The reflection plate comprises a first region close to one end of the light source with a higher brightness and a second region close to the other end of the light source with a lower brightness. The reflectivity of the first region is smaller than that of the second region.
