Title: PCB FIXATION STRUCTURE AND LIQUID CRYSTAL DISPLAY APPARATUS
Abstract:
A PCB fixation structure and a liquid crystal display apparatus. The PCB fixation structure fixes a PCB (50) on a back board (10) via an annular conductive foam (30) a conductive adhesive (20), thereby enhancing the contact between the PCB (50) and the back board (10), and improving the grounding of the PCB; the annular conductive foam (30) is then squeezed through a PCB housing (40), ensuring that the annular conductive foam (30) has an adequate compression ratio and thus has a good electric conductivity, and the grounding of the PCB is further improved, thereby being able to conduct ESD interference timely and effectively, preventing static electricity damages, simplifying the process of fixing the PCB and saving working time. The liquid crystal display apparatus with the PCB fixing structure is capable of simplifying the process of fixing a PCB in the liquid crystal display apparatus, saving working time, improving the grounding of the PCB and preventing static electricity damages.
