Abstract

Disclosed is an adjustable frame designed to secure a wide range of display screen sizes within a customer's "touch application" booth. Any existing PS/2* display can become touch sensitive when fitted in the frame. It overcomes the need for a special size-range of touch displays allowing users to select, fit and change the sizes of displays fitted to a standard touch application booth.

Multi Screen-Size Touch Display Frame for Booth Applications

      Disclosed is an adjustable frame designed to secure a wide
range of display screen sizes within a customer's "touch application"
booth.  Any existing PS/2* display can become touch sensitive when
fitted in the frame.  It overcomes the need for a special size-range
of touch displays allowing users to select, fit and change the sizes
of displays fitted to a standard touch application booth.

      Fig. 1 shows the basic mechanical structure of the frame 1.
Only one corner CRT support bracket 2 is shown; four are used.
Sliding mounts 3 on each corner allow for fitting of 12" to 17" CRT
displays 8 yet the frame 1 remains rigid enough for touch operation.
Each strain gauge 4 is attached to the cross bar 5 and to the display
attaching frame piece 2.  A flexi circuit 6 is used to allow the
movement of the strain gauge 4 on the sliding bar 5.  This circuit is
then fed along the frame down to a logic card that will perform all
the functions such as amplification of the signal, A/D conversion and
communications to a PC.  For neatness and space saving the components
could be part of the flexi-circuit 6.

      Fig. 2 shows in cross section how the display support bracket 2
attaches to the display edge 8 using the display front/rear bezel gap
7 as the main support point.  This allows for the fitting of all
sizes (8, 9 max & 10 min) of displays required.  The logic card can
be of the same design as an...
