Patent ID: 8264827

Claim:
A liquid crystal display, comprising: a housing having a side wall for defining a receiving space; a liquid crystal display module disposed in the receiving space of the housing; a touch panel disposed on a surface of the liquid crystal display module and having a horizontal side surface and a vertical side edge, wherein both of the horizontal side surface and the vertical side edge are adjacent to an inner surface of the side wall of the housing; and at least one fastening device clipping the horizontal side surface and the vertical side edge of the touch panel to the side wall of the housing for fastening the touch panel on the housing, and the fastening device comprising: two positioning components, each of which is a screw having an enlarged end and an end for screw-connecting; a fixed plate fixed on an outer surface of the side wall of the housing and extended along a second direction perpendicular to the horizontal side surface of the touch panel; and a pressing plate extended along a first direction parallel to the horizontal side surface of the touch panel and positioned on the fixed plate by the positioning components, the pressing plate having two positioned portions and a retaining plate facing the fixed plate, wherein each of the positioned portions comprises a slot formed on the pressing plate and extended along the first direction, each of two opposite sides of each of the positioned portions has a recess for containing the enlarged end of one of the positioning components, and the retaining plate vertically extended downward from the pressing plate along the second direction abuts against the vertical side edge of the touch panel for preventing the touch panel from moving along the first direction, and wherein a surface of the fixed plate facing the pressing plate has two positioned holes, each of which is corresponding to one of the positioned portions and has an inner thread for being screw-connected to the end for screw-connecting of the corresponding positioning component, wherein the positioning components movably pass through the positioned portions along the second direction perpendicular to the horizontal side surface to allow the pressing plate to selectively move along the first direction for adjusting a distance between the retaining plate and the fixed plate before the ends for screw-connecting of the positioning components are inserted into and screwed to the positioned holes, and the ends for screw-connecting of the positioning components are for being inserted into and screwed to the positioned holes for positioning the pressing plate on a predetermined position of the fixed plate; and wherein a lower surface of at least one portion of the pressing plate abuts against the horizontal side surface of the touch panel for preventing the touch panel from moving along the second direction perpendicular to the horizontal side surface.
