Patent number: 7751017Abstract: A display apparatus includes a backlight assembly, a display assembly and a board combining member. The backlight assembly includes a light source generating light and a container receiving the light source. The display assembly includes a display panel received in the container and displaying an image, a driving printed circuit board (“DPCB”) disposed on an outer face of the container, and a flexible printed circuit board (“FPCB”) connecting the DPCB to the display panel. The board combining member combines the DPCB with the outer face of the container to be capable of moving corresponding to a thermal expansion of the container such that a position of the DPCB with respect to the FPCB is not substantially changed. Thus, the FPCB is prevented from warping due to the thermal expansion of the container.Type: GrantFiled: February 20, 2008Date of Patent: July 6, 2010Assignee: Samsung Electronics Co., Ltd.Inventor: Dong-Sung Im
