  • Display apparatus and flexible substrate
    Patent number: 7414851
    Abstract: The present invention relates to a flexible substrate. More particularly, the present invention relates to a flexible substrate for a display apparatus. A display apparatus according to an embodiment of the present invention comprises a display panel in which an electrode is formed, a heat sink plate formed on a rear side of the display panel, a driving board formed on a rear side of the heat sink plate, and a flexible substrate for connecting the electrode and the driving board, wherein the flexible substrate is directly grounded to the heat sink plate. Accordingly, the noise of pulses supplied from the flexible substrate can be prevented and damage to the flexible substrate can be prohibited.
