Abstract:
1. A display device, comprising: a mold frame, including a series of optical sheets; a bottom chassis assembled to said mold frame, the bottom chassis defining a means for dissipating electromagnetic interference (EMI) coupled thereto; a top chassis assembled to said mold frame; a display panel positioned between said bottom chassis and said top chassis; a printed circuit board (PCB) having top and bottom major surfaces and being connected to said display panel, the PCB being disposed below the bottom chassis such that its bottom surface is closer to the bottom chassis than is the top surface of the PCB; and, one or more grounding protrusions formed to protrude from the bottom surface of said PCB and coupled to an electrical ground of the PCB, wherein the one or more grounding protrusions protrude beyond the bottom surface of the PCB by a protrusion distance that exceeds heights of any other components formed on the bottom surface of the PCB, and the one or more ground protrusions are disposed in contact with the bottom chassis so as to thereby couple at least some of EMI produced in the PCB to the bottom chassis.
