The display hanging plate assembly comprises a hanging plate and a connector, one end of the connector pivotally connects with a connecting block, and the other end of the connector rotatably connects with the hanging plate. In the bracket in order to prevent the display on the hanging plate from inclining downwards with the hanging plate by its own weight, two torsion springs are generally mounted on pins of the hanging plate to increase the resistance to downward rotation of the hanging plate. However, in the case of adjusting the angle of downward rotation of the hanging plate, people need to overcome the elastic force of the torsion springs, and the larger the angle of downward rotation, the larger the force required. As a result, the adjusting of the angle of the hanging plate is labor-consuming and is inconvenient to operate, and the control of the rotation of the hanging plate is not flexible. Also, in the prior art, an opening is formed at the bottom of a cable clip on a rocker arm of a flat panel TV bracket, a cable is packed into the cavity of the cable clip through the opening, so that the cable is likely to fall out of the cable clip from the opening at the bottom of the cable clip, affecting normal use of the flat panel TV bracket.
