Abstract
A touch screen mounting assembly for a liquid crystal display panel (LCD) and a method for fabricating a touch screen mounting assembly for use on a LCD panel are disclosed. The mounting assembly includes a bottom frame that has a plurality of attachment means mounted thereon, a backlight panel that has a plurality of pressure-sensitive transducers mounted thereon, a liquid crystal display panel, and a top frame for exerting pressure when mounted to the bottom frame such that a plurality of compressible springs biases the LCD panel towards the bottom frame when touched or contacted by a user. The pressure-sensitive transducers may be suitably piezoelectric transducers that produce a flow of electricity upon sensing a pressure.
Claims17
A touch screen mounting assembly for a liquid crystal display (LCD) panel comprising:
- a bottom frame having a substantially rectangular-shaped cavity therein for mounting a backlight panel thereto, said bottom frame being equipped with a plurality of attachment means each having a compressible spring and is situated on an outer periphery of the frame;
- a backlight panel for supplying illumination to said LCD panel and for mounting to said bottom frame, said backlight panel having a front surface opposite to a back surface that faces said bottom frame, said front surface having a plurality of pressure-sensitive transducers mounted thereto;
- a liquid crystal display panel positioned juxtaposed to said front surface of said backlight panel sandwiching said plurality of pressure-sensitive transducers therein between;
- and
- a top frame for compressing said compressible springs in said plurality of attachment means against said bottom frame by a plurality of tabs mounted peripherally on said top frame such that said plurality of compressible springs bias said LCD panel toward said bottom frame.
A method for fabricating a touch screen mounting assembly for use on a LCD panel comprising the steps of:
- providing a bottom frame having a substantially rectangular-shaped cavity therein for mounting a backlight panel thereto, said bottom frame being equipped, with a plurality of attachment means each having a compressible spring situated on an outer periphery of the frame;
- mounting a backlight panel for illuminating said LCD panel to said bottom frame, said backlight panel having a back surface and a front surface, said back surface intimately engages said bottom frame while said front surface having a plurality of pressure-sensitive transducers mounted at each distant corner of said backlight panel;
- positioning a LCD panel juxtaposed to said front surface of said backlight panel sandwiching said plurality of pressure-sensitive transducers therein between;
- mounting a top frame to said bottom frame with said backlight panel and said LCD panel sandwiched therein by fastening to said plurality of attachment means;
- and
- biasing said LCD panel toward said bottom frame by said plurality of compressible springs.
