Patent ID: 8773610

Claim:
A liquid crystal display, comprising: a plastic frame; at least one printed circuit board having a first surface, a second surface, and at least one first hole penetrating through the printed circuit board, and an end of the first hole being located at the first surface and another end of the first hole being located at the second surface, wherein the first surface and the second surface are two opposite surfaces of the printed circuit board; at least one pin disposed on the plastic frame; at least one slot formed on the pin; at least one first constraining part disposed on the side surface of the pin for constraining the printed circuit board between the first constraining part and the plastic frame, wherein the first constraining part is configured to be against the first surface of the printed circuit board; at least one second constraining part against second surface of the printed circuit board at least one second hole passing through the plastic frame; and a metal back plate disposed inside the plastic frame; wherein the printed circuit board is disposed outside the plastic frame, the second constraining part is disposed on the metal back plate and passing through the second hole to be against a grounding position of the printed circuit board, and the material of the second constraining part is metal; and a liquid crystal panel held by the plastic frame and electrically connected to the printed circuit board.
