Abstract

The visual quality of an LCD monitor is maximised when there is no additional transparent plate interposed between the LCD and the viewer. However, some users require a touch function or simply the inclusion of a protective, toughened, glass plate. This requires the additional plate to be mounted in front of the LCD.

Touch-Enabled LCD Monitor

   The visual quality of an LCD monitor is maximised when
there is no additional transparent plate interposed between the LCD
and the viewer.  However, some users require a touch function or
simply the inclusion of a protective, toughened, glass plate.  This
requires the additional plate to be mounted in front of the LCD.

   Usually the additional thickness of the plate and its
means of attachment is accommodated by placing a gasket between the
front and the rear covers, which adversely impacts the design
quality of the touch-enabled monitor.

   Figure 1 shows a simple and effective means of
accommodating the additional plate whilst enabling the manufacturing
operation of installing the additional plate to be simplified and
cost reduced.

   Figure 1(a) shows the improved structure without the touch
facility, while Fig 1(b) shows the structure with the additional
plate P in place.

   The front (A) and rear (B) covers are designed to fit one
inside the other, rather that abut against each other.  The overlap
between the two covers is such that they can be separated by an
amount sufficient to accommodate the thickness of the additional
plate yet still remain overlapped.  The required increase in
separation is achieved by simply placing additional spacers (C) on
the screw bosses by which the front and rear covers are attached to
each other.
