  • Publication number: 20130088844
    Abstract: The invention relates to a base of a display device, comprising a base body, a first wing connected to one side of the base body and a second wing connected to the other side of the base body. The base body comprises a pillar which supports the display device. The first wing and the second wing are hinged on base body in a swivelable manner so that the first wing and the second wing can swivel relative to the base body. Alternatively, the first wind and the second wing are detachably connected to the base body so that the first wing and the second wing can form different aspects relative to the base body. As a result, the first wing and the second wing can be adjusted relative to the base body in terms of positions and aspects according to requirements.
